DORIS JOHNSTONI. I met with one specimen at Hilbre, 1851. DORIS BILAMELLATA. Rocks at Hilbre Island, where the large brown variety is sometimes plentiful. At New Brighton, also, occasionally. A smaller and lighter coloured variety is abundant on the dock wall at Woodside, and along the Cheshire side of the Mersey. DORIS DEPRESSA. I once met with a specimen of this small species at Hilbre Island. DORIS PROXIMA. This species was extremely common on the shore between Egremont and New Brighton in August this year. There is an account of it in the "Annals of Natural History," for August, 1854, by Messrs. Alder and Hancock. Mr. Alder, to whom specimens were sent, writes, "it was first discovered on Birkenhead shore by Mr. Price. The Doris is so like Aspera' that it requires a critical eye to distinguish it, but when the tongue of each is examined they are quite different." White and yellow varieties are met with. I have taken it freely at Hilbre Island also. DORIS PILOSA. At Hilbre Island, Caldy Blacks, and other rocky places round our shores. A deep purplish black variety has been met with at Hilbre, and I believe also on the Mersey shore. DORIS SUBQUADRATA. The single specimen from which the figure in Alder and Hancock's work was drawn was taken at Torquay. During a visit to Caldy Blacks, Mr. Webster and myself were fortunate enough to find a second, which was sent to Mr. Alder, by whom the species was confirmed; it was in company with "Doris Pilosa." POLYCERA LESSONI. Genus POLYCERA. One dredged north of Wirral, 1852.-I. B. POLYCERA OCELLATA. Frequently taken at Hilbre, Egremont, and elsewhere. ANCULA CRISTATA. Genus ANCULA. Taken frequently at Hilbre. Dredged north of Wirral. Estuary of the Mersey. Mr. Price. Egremont shore. TRITONIA HOMBERGI. Family TRITONIDÆ. Genus TRITONIA. One specimen found at Hilbre by Mr. S. Archer. It has also been met with upon the western shore of the Mersey, near the entrance of the river. Its presence in these localities is rather remarkable, as it is a deep water species. TRITONIA PLEBEIA. Taken in the dredge at the north of Wirral. Family EOLIDID.E. Genus DENDRONOTUS. DENDRONOTUS ARBORESCENS. Very common at Hilbre until 1853, when it was seldom found. Plentiful about Woodside slip, and the adjoining stony ground.-Mr. Price. Pale yellow, and the more ordinary brown varieties are met with. Taken at New Brighton, 1854. Specimens small.-Mr. Price. It is by no means abundant as in former years. SO DOTO CORONATA. Genus DOTO. Taken once at Woodside.-Mr. Price. Genus EOLIS. EOLIS PAPILLOSA. Rocky places round the neighbouring shores. Hilbre, Caldy Blacks, New Brighton, &c. A small variety, not a third part of the ordinary size, and of lighter colour, taken at Hilbre, and on the Egremont shore, 1854. This was published formerly by Messrs. Alder and Hancock, under the title of "Eolis Obtusalis," "but," Mr. Alder writes, we have given it up as a species, and have united it with 'Papillosa.'" EOLIS CORONATA. 66 Stony ground. Hilbre and elsewhere. Some of the specimens found on the Egremont shore, which were sent to Mr. Alder, were the darkest coloured that he had seen from any locality. EOLIS DRUMMONDI. The most common species of Eolis about the neighbourhood. Always to be obtained at Hilbre. EOLIS LANDSBURGI. Until 1849, when I was so fortunate as to find one of this species at Hilbre, only a single specimen had been discovered at Saltcoats. In June, 1853, I found, as I considered, another in the same locality, which tallied in every respect with the former, size excepted, being nearly double the length. It was forwarded to Mr. Alder, but did not get into his possession until it was partially decomposed. Mr. Alder writes, "From an examination of the remains and the tongue it might be E. Landsburgi.'" EOLIS AURANTIACA. At Hilbre once or twice. Mr. Price has taken it at Woodside and New Brighton. EOLIS PICTA. Found at Hilbre twice or thrice. Egremont shore, 1854. EMBLETONIA Pallida. Genus EMBLETONIA. Discovered by Mr. Price upon Birkenhead shore. See "Annals of Natural History," August, 1854, where it is described by Messrs. Alder and Hancock. It differs from other British species in having a double row of papillæ at the sides. ANTIOPA HYALINA. Genus ANTIOPA. In July, 1851, in company with Mr. Price, we each picked up a specimen of this new species at Hilbre Island. One was sent to Mr. Alder, but did not arrive in a living state. In August, this year, I found a very fine one within a few yards of the same locality, which fortunately got into Mr. Alder's possession alive. Messrs. Alder and Hancock's description of the animal, in the "Annals of Natural History," for August, 1854, runs thus, "Pellucid, yellowish, with brown markings down the middle of the back, branchia elliptical, tuberculated, hyaline, with the central vessel fulvous; dorsal tentacles obtuse, obscurely laminated, united by a crest; oral tentacles united by a narrow veil." The second specimen, Mr. Alder remarks, "was more mature, and in better condition than the first, and differs from it in the greater length and more pointed character of the dorsal tentacles. The papillæ are much attenuated and elongated above, with the point enlarged and obtuse. The gland is darker and a little branched. The tail is also more produced. Length, 4-inch." Mr. Hancock has kindly furnished & drawing of the animal with his usual high finish and faithfulness of nature, which, it is hoped, will be engraved for the present volume. Not uncommon in gardens, cellars, and damp situations. LIMAX ARBORUM. Numerous at Upton in 1852, upon beech trees. They have not been seen since, though tracks have been observed upon the bark of the trees. LIMAX FLAVUS. In damp cellars not uncommon. Often found in publican's vaults.-Mr. Cameron. VITRINA PELLUCIDA. Family HELICIDE. Genus VITRINA. Amongst moss, under stones, and at the roots of grass, in woods and hedges. Generally distributed. More readily found in spring. ZONITES CELLARIUS. Genus ZONITES. Common in damp cellars, also amongst decaying wood, leaves, or other rubbish; in fields and hedges where there is moisture. General. |
