THE CONCHOLOGIST. 



A CORRESPONDENT writcs enquiring if our 

 paper is the organ of any society, and if 

 we vvill devote a page in each issue to the 

 reports of Conchological societies. We beg 

 to inform him and our readers that our 

 paper is connected with no society, nor is 

 it our intention of letting it become so. We 

 shall, however, always be pleased to receive 

 reports of societies, and, as for as it lies 

 within our power, to assist in any way in 

 the formation of such, believing, as we do, 

 that if well regulated and worked on practical 

 lines they are capable of being made centres 

 of great usefulness and interest. 



The only two Conchological societies we 

 are aware of are the Conchological Society of 

 Great Britain and Ireland, and the Manchester 

 Conchological Society, which is affiliated with 

 the former. If others exist we shall be pleased 

 to hear of them. 



We understand it is the intention of the 

 Council of the Conchological Society of Great 

 Britain and Ireland to issue very shortly a 

 new list of British Land and Freshwater 

 MoUusca. The Committee into whose hands 

 this important undertaking has been entrusted 

 are Messrs. J. W. Taylor, F.L.S., Wm. Nelson, 

 and W. Denison Roebuck, F.L.S. While no one 

 for a moment can question the ability or quali- 

 fications these gentlemen possess for such a 

 piece of work, a much larger committee 

 would, in our opinion, have ensured a better 

 list. A list of Land Freshwater and Marine 

 Mollusca compiled by the following gentlemen 

 is what is required: — T. D. A. Cockerell ; 

 the Rev. A. H. Cooke, M.A., F.L.S. ; 

 W. E. Hoyle, M.A., M.R.C.S., F.R.S.E. ; 

 J. T. Marshall; J. Cosmo Melvill, M.A., 

 F.L.S. ; William Nelson ; the Rev. Canon 

 Norman, M.A., D.C.L., F.R.S. ) W. Denison 



Roebuck, F.L.S. ; Edgar A. Smith, F.Z.S. ; 

 A. Somerville, B.Sc, F.L.S.; John W. Taylor, 

 F.L.S.; and the Rev. R. Boog Watson, B.A., 

 F.R.S.E., F.L.S. 



We are pleased to welcome an old friend in a 

 somewhat new guise — The British Naturalist 

 — in which our readers will find a Concho- 

 logical section under the able editorship of 

 Mr. T. D. A. Cockerell. 



ON THE SYNONYMY OF 



THE SO CALLED LIMAX ARBORUM AND 



AMALIA MARGINATA. 



lion. Li/irnyinii ami Assistant Curator to the Conchological 

 Society of Great Britain and Irelaml. 



I HAVE lately had some corres])ondence 

 with Mr. T. D. A. Cockerell with reference 

 to the above, and as the matter does not 

 seem to be clearly understood by all concho- 

 logists, I have undertaken, at Mr. Cockerell's 

 suggestion to place it in a little clearer light 

 than it has hitherto occupied. 



Limax marginatus, Miiller. 



= Limax /iiarginaiiis, Miiller, 1774. 



= Limax arborum, Bouch-Cli., 1838. 

 The form which we now term L. arboruiii, is, 

 in my opinion, identical with the L. f/iargi- 

 /latus of Miiller, a view which Mr. Cockerell 

 also takes. Of course this has nothing to 

 do with the L. marginatus of Drap., or the 

 one of British Authors, they both being Ainalia 

 as shown below. The Limax sylvestris, Scopoli, 

 1772, is also referable to Miiller's form, 

 Mr. Cockerell thinks, but his description is 

 too poor to admit of certainty.
