THE MOLLUSCA OF SUFFOLK.

THE MOLLUSCA OF SUFFOLK. BY OUR CONOHOLOGICAL MEMBERS.

THE compilation of a comprehensive account of the Land and Fresh-water Snails, along with Marine Shell-fish, of the County has been a simple matter, excepting in the way of synonymy, on account of the paucity and completeness of earlier literature upon the subject. The very generai segregation of the two groups has ever appeared unnatural to the Hon. Editor and is not perpetuated here, as has been the case in all local notices hitherto. We are unusually fortunate in possessing a most valuable basis for the former group so early as 1825, when appeared ' Desscriptions of Seven new British Land and Fresh-water Shells, with Observations upon many other Species, including a List of such as have been found in the County of Suffolk ' by the Rev. Revett Sheppard, F.L.S., dated from Wrabness Parsonage, May 16, 1822. " I have (says he) been induced to lay before the Society a list of those Shells hitherto discovered in Suffolk, by which it will be seen that the eastern* parts of this island are fertile in those elegant productions of Nature." Follows a bare catalogue of seventy kinds in the order of Linn aus, Draparnaud and Lamarck, whereof thirty-six are later elaborated in articles. Among these figure Teilina Henslowana, Turbo Offtonensis, Helix Somershamiensis, Helix Kirbii ( ' I hope this species will be called after one of the best of men, and best of friends, the Rev. William Kirby of Barham ' ), all of which titles but the first are unfortunately lost by priority : some records are from the ' estate of John Sheppard, Esq., of Campsey Ash,' others indifferently from ' my brother's garden at Campsey Ash ' ; at times the Revd. Revett collected, as at Friston Wood in May 1821, with his ' son.' The whole displays an industry and knowledge of Nature that this Society has been too slow in recognising, mainly because his publications appeared in a serial not in every library. John Sheppard of Monewden in Suffolk married Mary daughter of John Revett of Brandeston there ; he inherited the Manor of Morehall Hall in Campsey Ash in 1747 on the death of his cousin John Sheppard ; and died in 1793. They had sons, John of Campsey Ash, who married Letitia Wilson in 1797, had lssue, and died in 1824 ; The Revd. Revett, F.L.S. ; and Lieut. Frederic, fifth son, born 1790-1, died 1812, aged 21 (Charles Partndge, *Fairly obviously, it was D r . W . G .

Census of L a n d and Freshwater Mollusca, by W . D . Roebuck (Journ. Conch. Soc.). British Snails, by A. E. Ellis ; Oxford. List of British Marine Mollusca, by R. Winkworth, M.A., President Conch. Soc. et seqq. Numerous records on Mollusca in Trans, butiolk Naturalists' Soc.

Besides these really excellent papers in various periodicals, rough lists of local species have been occasionally included in parish histories, though such are usually too indefinite to be included here. Thus Sir John Cullum's dear old 1784 (postLinnean) History of Hawstead near Bury specifies no Mollusca ; but in the appendix on its hamlet of Hardwick he thence records (p. 233) " the sharp snail (Helix [Helicigona] lapicida), the bristly snail (Helix [Trichia] hispida), and the Turbo bidens " [Penn. Marpessa laminata, post.], along with ' that very beautiful bird, and the smallest of any English one, the golden crested wren (Motacilla Regulus), a constant inhabitant of the same garden.' The Pagets in 1834 refer to Mollusca around Yarmouth, but instance none. The " shells and fossils " listed in Wake's 1839 ' Southwold,' page 216, are mainly referrable to the latter and too vague to be reliable. Greene in 1891 included work done by Dr. Babington of Cockfield who acquired King's collection at the sale of Sudbury Museum ; Mr. E. B. Skepper of Bury (whose collection seems to have disappeared from Moyses-hall Museum there : notes on it in M3 are from Revd. E. N. Bloomfield); Miss F. B. Powles of Ipswich ; Mr. Frank Norgate of Sandy Downham; and our Original Member, the late Mr. G. T . Rope. T h e following enumeration is uniform with former comital ones e.g. The Fishes of Suffolk (Trans, ii 104); but, unlike this Society's resumes of Vertebrata (I.e. ii, 13 & 209), FOSSIL species are omitted from the present paper, on account of their multiplicity. Recent Shells may be mistaken in washed-out Fossils: hence such modern records as those of Anomia ephippium, L., Cyprina Islandica, L. and Calyptraea Chinensis, L., occurring in 'both periods, are suspicious until verified. Also populär titles are omitted : " I strongly deprecate English names. Most Mollusca have none or at most English translations of their Latin names. Every one knows what a Red Admiral Butterfly is but who what a Grove Snail is ? Mammals, birds, and fishes are all given under their English names by Bell (Mammals) Yarrel, (Birds & Fishes) and Couch (Fishes) but neither ForbesandHanley or Jeffreys give English names to Mollusca. If we don't give them to lepidoptera as Ed. Newman and South do, we can surely leave them out for Mollusca," considers Mr. Doughty, 15 March 1938. T h e British species of Mollusca (excluding all doubtfully authenticated kinds, those occurring in only the Channel Isles, and all fossils ; but including such introduetions, like Cochliella elegans, as have gained a firm footing here) Mr. J. R. Le B. Tomlin

of the British Museum, M.A., F.E.S., considers to total 795, whereof 606 are marine (in lit. 10 April 1938). Among the odd 189, we boast the respectable proportion of 120 ; but among Sea Shells Suffolk must ever be weak, on account of the lack of all rocks off our coast, the best Substitutes for which are oleaginous London-clay at Bawdsey and adventitious concrete blocks. Hence it is improbable that the present total of 234 species will ever become materialy extended. PELECYPODA (Bivalves). 1.

*Our earliest record of this species is contained in a comparison with its fossil form in an anonymous letter printed in the Gentleman's Magazine of 1788, vol. lviii, p. 321, carefully extracted by our Member, Mr. Lingwood :—" Feb. 19. Mr. Urban.—I wish, among your many ingenious correspondents, the following phieonomenon could be explained. Upon the coast of Suffolk, from the high cliff (which we descend to Landguard Fort) to Baudsey Ferry, the cliff is a composition of marine shells, among which are found a great number of the Spiral wilk-shells. Time, and the want of an animated inhabitant, has given them a yellow coat ; but they are exactly the same, as to size and form, with the life-shell on the beach beneath, of which [but mainly of Buccinum undatum, one [guesses a cart might be filled in an hour, with this very Singular difference that every shell in the cliff has its Spiral turn contrary to that of the lifeshell. I have dug in the cliff, at times, for years, and never could find a Single shell in it that did not twist as in plate ii, fig. 4 [showing Form contraria, Gmel.], while all the life-shells are as in fig .5 [typical N. antiqua]. We call the yellow ones ante-diluvians ; but did the deiuge invert their nature, Mr. Urban ? Yours etc., A."—Ed.

RECENT BIRDS ROUND LOWESTOFT. BY FREDERICK C .

COOK.

1937 OCTOBER.—A small party of Lapwings arrived from the east on 3rd. A boisterous north-easter on 5th favoured the advent of a large number of Song-thrushes, several flocks of which came from eastward in early morning and one or two were washed ashore : it is difficult to judge how many small Birds perish while crossing the North Sea, owing to the ever-increasing hordes of Gulls that patrol the foreshore on the look out for any edible morsels. At night many Song-thrushes were audible passing over the town. The first Redwing was seen on 6th and, from 7th onwards, their call-notes could be heard nightly, as they crossed the coastline. Our Member, Mr. Jenner, to whom I am indebted for certain of these notes, reported on 12th a male Ringouzel on the north denes here. Düring 17th-31st persisted a steady immigration of Corvidoe, Starlings and Sky-larks. No spectacular rushes of migrants occurred, but one morning a Starling was seen to drop, from an incoming flock, into the waves ; it was washed ashore exhausted but, when an attempt was made to pick it up, enough strength was mustered to flutter
