COPIOUS NOTICES OF THE NATURAL HISTORY OF THE DISTRICT. EDITED BY EDWARD DAY McNICOLL, HONORARY SURGEON TO THE SOUTHPORT INFIRMARY ; FORMERLY RESIDENT MEDICAL OFFICER TO THE SOUTHPORT CONVALESCENT HOSPITAL. TH I RD EDITION SOUTHPORT : ROBERT JOHNSON AND CO. LIMITED, " VISITER " OFFICE, LORD STREET. 1883. PREFACE. ^W^HE first edition of this little book was compiled by my father in 1859. The sale was rapid, and in 1861 another edition was called for and soon exhausted. That no work dealing with the same subject has equalled my father's in scope and completeness has been freely admitted. To obtain a copy although frequent attempts to do so have been made by the public has for many years been impossible. My father's long illness, followed by his lamented death in 1868, doubtless helped to prevent a re- newed issue. The approaching visit of the British Association to South- port is an event of importance so great, and is so likely to attract general attention to the town and its history, as well as to promote local interest in all pertaining to it, that a more fitting opportunity could hardly be found for now publishing a new edition. Although the form of the work remains the same, it is hoped that in substance it may lay some claim to be considered much improved. The re- markable, almost unexampled, progress and development 868701 vi. PREFACE. of Southport, during the last twenty years, has called for a total re-casting and re-writing of much that the former editions contained the portions, in particular, which are descriptive of the public buildings and institutions. Many of these have been founded or enlarged within the period named. The preface to my father's original work contained a paragraph, the re-printing of which, verbatim, will indicate why even increased space is given to the Natural History. " I need not apologise for the Natural History occupying so large a portion of the following pages. The motive has been to encourage useful and agreeable mental occupation on the part of visitors whose stay in Southport is more or less prolonged, and whose minds would, in the absence of some external object of thought, turn and prey upon themselves. This continual contemplation of their own condition the result of the depression dependent upon disease, and absence from the ordinary engagements of life needs to be carefully guarded against, and I have not thought it out of place in a work partly medical to suggest a substitute." With a view to promoting my father's excellent object in the best manner possible, I have sought the assistance, whilst preparing this new edition, of some of the gentlemen to whom he was himself indebted for help. In this connection it gives me pleasure to name Mr. Charles H. Brown, to whom my thanks are due for undertaking the chapters upon the Shells, the Zoophytes, and the Foraminifera ; and Mr. Leo Grindon, who has dealt with the Botany, and supervised the Natural History in general. Mr. Baxendell, the well-known meteorologist, has kindly supplied me with some Tables, which present, in the clearest manner, the results of the records daily made at the Ob- servatory in Hesketh Park, extending over a period of eleven years. These Tables have not before been published in the present form, and are a distinct and valuable feature of the volume. To Dr. Vernon, our valued Sanitary Medical Officer, my thanks are also due for placing at my disposal information which he had collected for independent purposes. E. D. McN. SOUTHPORT, AUGUST, 1883.

The animals, which are annulose or articulated, with jointed legs, possess a double or complete circulatory system, and respire by means of bronchise, or gills. The external shell, like that of insects, is composed of a dense horny substance called chitine, often strengthened, as in the crab and lobster, by the deposition of carbonate of lime. The body, being jointed, possesses considerable freedom of motion. The typical number of rings is twenty-one, but these are often soldered together, as we may observe in the crab, so that their relations are obscured. The animal has the power of casting the shell at intervals, and renewing it as the increased growth of the body requires. Otherwise, from the unyielding nature of the carapace, it could not grow. SPECIES OCCURRING AT SOUTHPORT. Long-legged Spider Crab (Stenorhynchus Phalangtum). This curious species is sometimes found on the sands near low water mark ; all the specimens we have found have been weakly and damaged, though living. Slender Spider Crab (Stenorhynchus lenuirostris). Bears con- siderable resemblance to the preceding, but is more slender in its parts, and has little pubescence on the legs. Less abundant than the former. Scorpion Spider Crab (Inachus Dorsettensis). In this species the rostrum is much shorter than in the two preceding, and the hue is much duller. Hyas araneus. A specimen was once found near where the Whitworth guns were placed. When the legs were extended it covered a space of four inches and a half 112 A HANDBOOK FOR SOUTHPORT. by three in width. The colours were not obscured, though it had various shells and zoophytes adhering to it. Harbour Crab (Carrinus Mcenas). This is the most abundant kind found on the shore ; sometimes eaten by the poor ; though small, the flavour is good. Portrtmnus variegatus. The shell of this species may be found on the sands, but we have not seen it in the living state. Velvet Swimming Crab (Portumnus puber). Rare ; only one specimen, and that in an exhausted state, has been found to my knowledge. Cleansing Swimming Crab (Portumnus Depurator). Common ; very active, and swims with great rapidity, burying itself in the sand as the water recedes. Common Pea Crab (PinnotJieres Pisum}. Resides in shells, oysters, scallops, cockles, &c. The sexes vary much in appearance, and have, until lately, been considered as distinct species ; the female is the P. varians of authors. Angular Crab (Gonoplax angulatd). This rare species was found by Mr. Graves beyond the end of the Pier. The colours were brighter than in most other kinds. Masked Crab (Corystes Cassivelaunus). A common species, and may be found at most seasons. In the female the front legs are less than half the length of those of the male. Common Hermit Crab (Pagurus Bernhardus). The most abundant species on our shore, generally inhabiting the shell of the common whelk ; when left dry it contrives to turn the mouth of the shell downwards. It is very THE CRUSTACEA. 113 pugnacious ; we are unacquainted with its enemies, but have met with great numbers with the abdomen and all the posterior parts eaten away. Pagurus ulidianus ? We name this species with some doubt, having met with numerous specimens inhabiting the shells of Natica monilifera, which have a strong resemblance to the figure of this species in Bell's " British Crustacea." Norway Lobster (Nephrops Norvegicus}. This beautiful species is given on the authority of Mr. James Glover. Common Shrimp {Crangon vulgaris). Common Prawn {Pandalus annulicornis). Occasionally taken by the shrimpers, but not common, and much smaller than on the south coasts. Minute Porcelain Crab Porcellana longicornis}. This minute species is often found on the sponge-like base of the Lobster's-horn Coralline ; it is obtained from the size of mustard seed to a quarter of an inch in diameter, and varies in colour from a dull pale red to a brilliant scarlet, intermixed with golden yellow. Mysis Chamceleon. A specimen was found in 1861. Pychnogonium littorale. A suctorial crustacean. J. G. CHAPTER VIII. I care not, Fortune, what you me deny ; You cannot rob me of free nature's grace ; You cannot shut the windows of the sky Through which Aurora shows her brightening face ; You cannot bar my constant feet to trace The lonely shore at dewy morn and eve. Let health my nerves and finer fibres brace, And I their toys to the great children leave ; Of nature, feeling, virtue, nought can me bereave. THOMSON. MOLLUSCA OF SOUTHPORT. HE Mollusca are destitute of internal skeleton, and have soft bodies, often protected by an external shell, as in the banded snail of our sandhills (Helix nemoralis}, and the common cockle. The shell cannot be regarded as essential; for of two species closely allied in structure, e.g., the snail and slug, it is often present in one, and absent or very imperfectly developed in the other. The Mollusca are further distinguished from the other great sections of the invertebrate division of the Animal Kingdom, the Articulata and Radiata, by the want of sym- THE MOLLUSCA. 115 metry in the two halves of the body, and the absence of joints or articulations, and lateral locomotive appendages. The majority of our Shells are divided into two classes Bivalves and Univalves. The Bivalve is a shell in two parts, a right and left valve, connected by a hinge. The Univalve is a conical or spiral shell, often closed by an operculum, which is a plate attached to the foot of the animal, corres- ponding in shape to the mouth of the shell. " The Mollusca, though nearly all sedentary in their habits, are in their earlier stages swimming animals, being provided with cilia which enable them to move freely about. Aided by these and the ocean currents, they are dispersed, sometimes to immense distances, until they meet with conditions suitable to their growth. It is a remarkable fact that the Bivalves, at this period of their lives, have eyes, to aid them in their movements." Thus there is a natural means by which their over accumulation in any particular part is prevented. After a few days of this free and sportive life, they begin to settle down to the conditions and localities each is destined to occupy. The limpet attaches itself to the rock, between high and low water mark ; the cockle, the mya, and the razor-fish bury themselves in the sand and mud ; the Teredines attack and burrow into the sides of ships or the hardest wood, and by their silent and ceaseless operations undermine some of the most important works of man ; the Pholas excavates itself a home in the rocks and cliffs, by what means science has failed to discover ; the mussel forms itself a byssus or cable, by which it is attached to rocks and timber, and one species spins itself a silken nest. Some tribes retain the power of moving about ; the Pecten and the Pinna take flying leaps Il6 A HANDBOOK FOR SOUTHPORT. through the water by rapidly opening and closing their valves, the large river mussel pushes itself along with its foot, and the cockle jumps along the sand. The Univalves are provided with a large muscular foot, by which they crawl along the bottom of the sea, or upon aquatic plants and sea-weeds. They have a head, eyes, a mouth armed with jaws, and a tongue, called a lingual ribbon, which is covered with a variable number of minute siliceous teeth. They feed upon confervas, sea-weeds, and zoophytes ; many of them are carni- vorous, attacking each other, and also the quiet bivalves. With their file-like tongue they rasp a small hole through the shell, and then devour the helpless inmate ; this will explain to the shell-gatherer why so many of the shells he picks up on the shore have little round holes drilled through them. The Bivalves live upon the animalcula and microscopic vegetable matter in the surrounding water; it is carried into the digestive cavities of the animal by currents caused by the action of their ciliary apparatus. A stranger coming to Southport from one of the inland counties for the purpose of collecting shells, would probably be very much disappointed on his first visit to the shore, as there are certainly very few shells to be found in the imme- diate vicinity of the town. The best collecting ground is from Birkdale to Formby, at high-water mark, and on the banks near low-water at high-water mark during the period of the highest tides, especially after heavy west or south-west gales, and near low- water on the slopes of banks during low tides. It is also well to examine the shore at extreme low-water during the times of the highest tides of the year, as at those parts which are not often left uncovered by the water, Mya THE MOLLUSCA. 117 truncata is occasionally found, with its long and curious syphonal tube, alive and perfect. Several minute species may be found by collecting the broken shell and sand from the ripple marks and the slopes of banks, and examining a small quantity at a time in a shallow dish of water, at home. Dredging, unless at a very considerable distance out, is un- productive; scarcely anything can be obtained but species which may be commonly found on the shore. A collector may make a very pleasant excursion by taking the train to Formby, crossing the sandhills to the shore, about a mile distant, and walking back to Southport, in all from eight to nine miles. A great many shells and other marine curiosities may be found during the walk, and it avoids an otherwise fatiguing return journey. The Mollusca which have been found on this coast up to the present time, number 146 species. Of these 104 are marine, 7 of them being naked Mollusca (3 Nudibranchs and 4 Sepiadae); and 42 are land and fresh water shells. The latter not being migratory to any extent, or not so subject to causes of removal, are, of course, actually native, or indige- nous to the district. Of the marine species, judging from a lengthened period of observation, 43 may be considered common, or native to the immediate coast ; 35 are occasional visitors, living, say within a radius of fifty or sixty miles ; and 26 species occur so rarely, live at probably such a distance, and require such conditions, as to oblige us to consider them quite foreign to our shore. These 146 species have been found in a space of seven or eight miles along the shore, and extending about two miles inland. In so small a space, and considering how barren non-observers might suppose the Il8 A HANDBOOK FOR SOUTHPORT. district to be, the collection may be considered a very fair proportion of the whole British Conchology, which comprises about 600 species. MARINE SHELLS (BIVALVES). ACEPHALA LAMELLIBRANCHIATA. PHOLADIDjE. Pholas crispata. Rare; small living specimens have been found in pieces of rotten wood washed up by the tides, and large single valves occasionally. The nearest habitat for this species is Hilbre Island, at the mouth of the Dee, where fine living specimens may be found burrow- ing in the red sandstone rock at extreme low water. Pholas Candida. Occasionally washed up alive, during very heavy gales ; single valves common at all times. GASTROCH/ENID/E. Saxicava rugosa. Very rare ; has been found burrowing in pieces of the zoophyte Alcyonium digitahtm, and also attached to Modiola Modiolus when brought up from deep water by the fishermen. MYAD/E. Mya truncata. Not uncommon. Fine specimens may some- times be taken at extreme low water, during high spring tides. Mya arenaria. Single valves are not uncommon ; perfect shells very rare. CORBULID/E. Corbula nucleus (the little basket). Occasionally found at high water mark, and on slopes of banks nearer low water. One valve is larger than the other ; the smaller THE MOLLUSCA. 119 one has the appearance of being pressed into the larger, a feature by which the species may be instantly recognised. ANATINID^E. Thraria phaseolina. One of our most beautiful shells ; rather abundant after high tides, and very fine. Thracia convexa. Very rare, and single valves only. SOLENID^E. Solen marginatus (Sword Shell). Rare, and generally single valves ; the shell is from four to six inches long, three- quarters of an inch broad, with a groove indented at the hinder margin. Solen Siliqua (Razor Shell). Good perfect shells have been found, but rarely ; single valves occasionally. This species sometimes attains a great size, nine or ten inches long, and an inch and a half broad. In many parts of the kingdom it is used as an article of food, and considered very delicate eating ; it lives buried in the sand at low water, from one to two feet deep. The creatures are caught by pushing crooked wires down the hole and hauling them up, or a little salt is dropped down the hole, which rather incommodes the animal. It rises up to see what is the matter, and is seized ; but if thrown upon the sand will very quickly work its way down again with its powerful muscular foot. Solen Ensis (the Scymitar). Very abundant and fine. Three to four inches long, and curved like a bow. Solen Ensis (Var. magna). Double the size of the preceding, and very rare. 120 A HANDBOOK FOR SOUTHPORT. Solen pelluridus. Found attached to bunches of coralline ; rather scarce; from an inch and a half to two inches long, and a quarter broad ; the hinge margin straight, the outer margin bowed. A novice would perhaps mistake the young Ceratisolen Legumen for this species; the difference is easily known by the position of the hinge ; in all the Solens it is near one end ; in C. legumen it is in the centre of the hinge margin. Solen coarcticus. Solen candidus. Single valves of these two latter species, fine and in good condition, have been found. SOLECURTIDJE. Ceratisolen Legumen (the Peas Pod). This one has a long flat shell, as the name denotes ; it lives buried in the sand at extreme low water ; rather common. TELLINID^E. Psammobia ferroensis (Sunset Shell). A flat elongated oval shell, rounded at one end, and squarish at the other end, and prettily rayed with pink from the hinge to the front margin. Common as a British species, but rare at South- port. Sometimes found perfect, attached to bunches of corallines. Tellina tenuis. Common. A very pretty species, the shell variously coloured, rose, pink, yellow, white, etc. ; flat or compressed, rounded in front, attenuated behind, about one inch long and five-eighths wide. Tellina fabula. Abundant ; one valve of this species is smooth, the other, upon close examination, will be found to be marked with very fine concentric lines, which cause it to be slightly iridescent. They are mostly about three THE MOLLUSCA. 121 quarters of an inch long, and half an inch wide, very much compressed, rounded in front, attenuated behind, much more so than Tellina tennis, and nearly white. Tellina donacina. An elegant oval shell, radiant with the colours of the setting sun ; single valves only have been found. Tellina solidula, one of our commonest shells, varying in colour through all the shades from crimson to yellow. Roundish and solid, from one quarter to three quarters of an inch in diameter. Syndosmia alba. A pretty oval, shining, rather pellucid, white shell, moderately plentiful. Scrobicularia piperata. Not uncommon ; found in the greatest numbers opposite the Promenade, especially after a heavy sea, when it is washed up from the mud in which it burrows. Very flat, round, white, and varies in size from half an inch to an inch and a half in diameter. DONACID^E. Donax anatinus (Wedge Shell). Common about low-water mark, and often very fine. Although one of our com- monest shells it is not the least handsome, being a light olive colour outside, and frequently a brilliant clouded violet within. MACTRID^E. Mactra subtruncata. Rather common, and generally small. White, solid, and somewhat triangular in shape. Mactra elliptica. I have found one good perfect specimen only of this shell. 122 A HANDBOOK FOR SOUTHPORT. Mactra stultorum. Very common and fine. Sometimes at low-water, lying in groups of hundreds together, within spaces of a few yards. The gulls break immense numbers to get at the animals. Mactra solida. A few single valves have been found. Lutraria elliptica. Single valves are occasionally met with : perfect shells very rarely. It is a large, oblong, rather flat shell, gaping or open at the extremities. Tapes pullastra. Artemis liruta. A few single valves of the two latter species have been found. Species that are so rarely picked up, and then only in single valves, are, as a rule, found attached to corallines. VENERID^E. Venus striatula. Common. Triangular. Looking at the shell edgeways, it is heart-shaped, has highly raised concentric lines, and is sometimes handsomely marked with rich brown rays. Venus ovata. Very rare. Similar in shape to a cockle, but small and white, and the sculpture much finer. Ludnopsis undata. Moderately common. A roundish shell, white, slightly tinged with rust colour ; varies from a quarter to three quarters of an inch in length and breadth. CYPRINID;E. Cyprina Islandica. Perfect shells of this fine species are rarely to be met with ; single valves not uncommon. CARDIAD.E. Cardium echinatum. A large species of the Cockle tribe, with thick radiating ribs, bristling with tuberculous spines. THE MOLLUSCA. 123 Single valves are common ; perfect double specimens may sometimes be met with after high tides. Cardium edule (Common Cockle). A very common shellfish about Southport at all times. In 1858, a cockle-bed or " scour," as it is locally termed, was discovered about five miles north-east of the town, where the cockles were so numerous as to be literally shovelled up with spades ; the yield for several months was from ten to fifteen tons a-week. It is scarcely possible to realize the prodigious numbers taken from the bank, as a ton contains about 80,000 individual cockles. Cardium Norvegicum. A small delicate-looking shell ; single valves found upon corallines. LUCINID^E. Lucina leucoma. Extremely rare ; one or two single valves only found. KELLIAD^E. Montacuta ferruginosa. Very rare, and single valves. A small white, oval, semi-transparent shell, about three- sixteenths of an inch long, generally stained with rust- colour. This and the following species are found by collecting and washing the sand and broken shell from the ripple-marks and slopes of banks. Montacuta bidentata. Moderately common A minute white, oval, almost transparent shell; about one-eighth of an inch long. Mytilus edulis (Common Mussel). Common. Sometimes in great numbers attached to pieces of wood or sea-weed. I 24 A HANDBOOK FOR SOUTHPORT. Modiola modiolus (Horse Mussel). Sometimes brought up by the fishermen, and frequently very large, from five to six inches in length. Modiola tulipa. This is a pretty translucent radiated shell. Good living examples have been found at low water, opposite Birkdale. Crenella discors. Rare. Has been found at low water, burrowing in A. digitatum. Nucula nucleus. Not common. Generally single valves attached to bunches of coralline. A small dull olive- coloured shell, the inside pearly white, and about twenty minute teeth on the margin at one side of the hinge, and ten at the other side. Leda caudata. Several specimens have been found on the Birkdale shore. OSTREAD/E. Pecten maximus (the Great Scallop). Great numbers of this, our largest British bivalve, are brought up by the fishermen. Pecten opercularis (the Common Scallop, or Fan Shell). Not uncommon, but generally small ; a handsome species, varying much in colour, being sometimes yellow, orange, crimson, brown, purple, white, or mottled. Pecten varius. Not commonly found, but on one occasion ten or a dozen were picked up. Ostrea edulis (the Oyster). Not common on the shore ; occasionally brought up by the fishermen. THE MOLLUSCA. 125 Anomia ephippium. Occasionally found upon Modiola modiolus. This curious mollusk is attached to shells, rocks, and stones by a muscle projected through an orifice in the lower valve, near the hinge ; it is a lustrous, pearly shell, and adapts itself to the shape of the body to which it is attached. Anomia patellaformis. Anomia aculeata. Like the ephippium, these two latter have been found on Modiola modiolus. UNIVALVES. GASTEROPODA NUDIBRA NCHIA TA . EOLIDID^E. CEolis coronata. (Eolis papillosa. DOR1DID.&. Doris Johnstoni. The Nudibranchiata are the naked mollusks or sea-slugs. They are curious, and some of them beautiful animals. We owe their presence to the construction of the Pier, as they are found on its timbers and on the stones heaped round their foundations. GASTEROPODA PR OSOBRA NCHIA TA . PATELLID^E. Patella vulgata (Common Limpet). Rare, and when found very much worn. Patella athletica. Like the above, very rare. DENTALIAD^E. Dentalium entalis (Tooth Shell). Some years ago this was a common shell, but now is only occasionally found, and 126 A HANDBOOK FOR SOUTHPORT. generally attached to corallines. Fine specimens are about an inch and a half long, tubular, tapering to the posterior end, and slightly curved ; perfectly white. Dentalium Tarentinum. The same remarks apply to this species as to D. entalis, with the exception of the specific differences. It is a thicker and straighter shell, the posterior end marked with very fine raised lines, length- wise, so fine as to require the aid of a microscope to discover them ; they are the principal characteristic mark of the species. Pileopsis Hungaricus. Shaped like the conventional cap of Liberty. Many years ago, when tides were deep on the foreshore, this was sometimes found, but is now ex- tremely rare. Alterations in channels and sandbanks influence the occurrence of shells. FISSURELLID^E. Emarginula reticulata. Rare. Found at high-water mark, and amongst corallines. In shape like a cap of Liberty, with a slit in the front margin. TROCHIADjE. Trochus zizyphinus (Top Shell). Moderately common. A cone-shaped shell, granulated in narrow spiral bands. LITTORINID^. Littorina littorea (Periwinkle). One of the most abundant shells on rocky coasts. Formerly uncommon at Southport, but since the construction of the Pier may be found in abundance. Littorina rudis. Rare. A smaller and lighter coloured shell than the last. THE MOLLUSCA. 127 Littorina littoralis. Good fresh specimens have been found. Rissoa vitrea. Rare. Minute, shining white. Found by col- lecting and washing sand, as previously stated. Rissoa ulvcK. Very common. In walking along the shore we frequently see patches of what the stranger would suppose to be black sand ; if a portion of it be taken up it will be found to be a mass of these small shells. Rissoa castanca. Rather rare. Found amongst R. ulvcz, and similar in shape and colour, but very much larger. I named this shell what I believed it to be ; Jeffries has examined it, and says it is an unrecognised variety oiulvce. TURRITELLID^E. Turritella communis (the Common Cockspur). Very common on most parts of the shore. Ccecum glabrum. A minute shell found in the fine shell debris and sand which I have taken home to dry in order to search for Foraminifera. CERITHIADyE. Apporhais pes-pelecani (the Bird's-foot Shell). A handsome and not uncommon species. The lip is extended out in such a way as to resemble a bird's webbed foot, from which its specific name is derived. Cerithium reticulatum. A rather worn specimen found when searching for Foraminifera SCALARIAD/E. Scalaria Turtonis (Wentle-trap, or Double Cockspur). Not uncommon. A handsome shell, turreted in shape, the whorls round and distinct, and crossed lengthwise with rather flat, pale brown, moderately close ribs. 128 A HANDBOOK FOR SOUTHPORT. Scalaria communis (Common Wentle-trap). Moderately- common. Same shape as the preceding, but the whorls more distinct, and the ribs thicker and more prominent. PYRAMIDELLID^E. Aclis supranitida. Rare. A pretty but very small shell, from one-tenth to three-tenths of an inch long, conical or turreted in shape. Good specimens are ornamented with raised spiral lines or ridges. It is considered rather rare as a British species. Found by collecting and washing the sand as previously stated. Aclis ascaris. Also one of the rare minute species, and found with the above. Eulima polita. Very rare. Lanceolate or tapering in shape, being about five-eighths of an inch long and one-eighth broad at the base ; colour, a shining porcelain white. Eulima subulata. Not uncommon. Very narrow, finely tapering, light brown, with spiral bands of a darker shade. Chemnitzia elegantissima. Very rare. A minute, white, spiral shell, with elevated oblique ribs on the whorls. Some- times found along with A. supranitida. Chemnitzia rufa. Found with the above. Odostonna interstincta. Rare. Found with the above. A minute species, requiring the aid of the microscope for identification. It is perfectly white, with longitudinal ribs upon the whorls. Odostomia indistincta. Odostomia rissoides var. dubia. These, like previous minute species, are rare, not only on the Southport shore, but generally ; they are found when searching for Foraminifera, most of them being difficult THE MOLLUSCA. 129 to identify with certainty. Were named for me by our great authority, Mr. Jeffries. NATICID.*. Natica monilifera. Common. A handsome shell, being glob- ular in shape, highly polished, and ornamented with a spiral band of brown spots. Natica nitida. Not common. Similar to N. monilifera, but smaller, about a quarter of an inch in diameter, and not quite so globular, the spiral a little more produced. MURICIDjE. Murex erinaceus (Sting Winkle). Not uncommon, though generally rather small. Nassa incrassata (Dog Whelk). Rare, though common as a British species. In shape it is similar to the common whelk, about half an inch long, with thick longitudinal ribs. Purpura lapillus. Not common. Being naturally an inhabit- ant of rocky localities, the specimens are often much worn when they arrive upon the Southport shore. It is fusiform in shape, very solid, and about an inch long. The animal secretes a milky fluid, which in former times was used in the production of a rich purple dye. Buccinum undatum (Common Whelk). Moderately plentiful ; very fine specimens may sometimes be found after storms. This is a common shell all round the British coasts. In many parts it is taken in great numbers, and used for bait ; and quantities are sent to the London markets, where they are boiled and eaten. FUSHS Islandicus. Very rare : generally weather-worn. 130 A HANDBOOK FOR SOUTHPORT. Fusus antiquus. Common after heavy gales, in company with the whelks, from which it may be known by the canal being more elongated, and the shell generally smoother and more tapering. The fishermen sometimes bring up splendid specimens from deep water, measuring six to seven inches long, and perfectly white. Trophon muricatus. Very uncommon. I have only found one good specimen. CONID.*. Mangelia gracilis. Very rare ; one or two specimens have been found near low water. Cypraa Europoea (Cowrie). Not common. It is about the size and shape of a coffee berry, with raised lines or ribs across ; a pale flesh colour. GASTEROPODA O PISTHOBRANCHIATA. The Mollusks of this order may be termed sea-slugs, since the shell, when it exists, is usually small and thin, and wholly or partially concealed by the animal. Cylichna cylindracea (the Paper Roll). So named from its shape. Rare on the Southport coast. About half an inch long, and three-sixteenths of an inch wide ; white and shining. Cylichna obtusa. Similar to the above, but half the length. A few years ago this shell was plentiful close to the town; THE MOLLUSCA. 131 it is now more abundant four or five miles to the west, at high-water mark. Tornatella fasciata. Very abundant. Not unlike a shuttle in shape, but broader in proportion, and beautifully coloured with bands of pink and white. Scaphander lignarius. Many years ago this was not an un- common shell on our shore ; it is now extremely rare. Philine aperia. Common. An extremely thin, white, trans- lucent shell, without spire, and a wide open mouth. CEPHALOPODA DIBRANCHIA TA. SEPIADjE. Sepia officinalis (the Common Cuttle-fish). The internal shell of this mollusk is occasionally washed up in considerable numbers during heavy gales in the winter. It is six to eight inches long, three inches in width, oval, and ex- tremely light in proportion to the bulk. The class Cepha- lopoda ranks the highest in the mollusca, as in the complexity of its organisation it approaches most nearly to the vertebrated animals. It is named from the loco- motive organs being arranged round the head ; when in the water, or crawling amongst rocks or on the strand, the animal has the appearance of being head downwards. The Sepiadae have eight short lanceolate, and two long tentacular arms. The large and prominent eyes are situated underneath the arms, one on each side ; above, in the centre of the circle of arms, is a strong horny beak. The arms and tentacula, besides being organs of loco- motion, serve to catch and hold their prey ; and, as they 132 A HANDBOOK FOR SOUTHPORT. are covered with small suckers, they are enabled to maintain so tenacious a hold that any unfortunate crab or fish with which they come in contact is left without escape. Whilst possessing such powers of offence, they are gifted with most singular means of defence. Like the chameleon, they have the power of changing their colour to delude their foes ; they also possess a bag, from which, when pursued, they eject a quantity of inky fluid, which envelopes them in a black cloud, and covers their escape. The contents of the ink-bag supply the brown pigment called sepia, used by artists. Sepia biserialis. A single specimen of the internal shell or bone of this rare species has been found on the Southport shore. It is much smaller than S. officinalis, lanceolate in shape, the point curved a little outwards, and the base slightly inwards. Sepiola Atlantica. A much smaller animal than the common Cuttle. I have seen only one good specimen found on the shore. Voligo vulgaris. A fine specimen has been taken at the end of the Pier. LAND AND FRESH-WATER SHELLS. ACEPHALA LAMELLTBRANCHIATA. CYCLADIDyE. Cydas rivicola (River Cycle or Fresh-water" Cockle). Found in many of the streams and ditches about Southport, but small ; in the canal at Burscough Bridge, abundant and fine. In shape this shell is similar to a young cockle, but more compressed ; finely striated, greenish THE MOLLUSCA. 133 brown in colour, with a narrow yellow band round the margin. Cyclas cornea (Horny Cycle). In almost any ditch. A round and dumpy shell, generally dark brown, varying in size from one-eighth to half an inch in diameter. Cyclas calyculata (Capped Cycle). Found sparingly in a stream by the first bridge beyond Churchtown, along the road to Martin Mere. A very transparent shell, about a quarter of an inch long ; the umbones the parts above the hinge very prominent. Pisidium amnicum (River Pera). Not uncommon in ditches on the Moss, and on the Martin Mere road, beyond Churchtown, but very small, rarely measuring more than one-eighth of an inch long; common and very fine in the canal at Burscough Bridge. In shape obliquely oval, with minute raised ribs. UNIONID.
