10 M. A. Schmidt on a neiv species of Clausilia. 



II. — Description of a new Species of Clausilia fi-ojn the neigh- 

 bourhood of Cheltenham. By A. Schmidt. 



To the Editors of the Annals of Natural History. 



Gentlemen, 23 Chesham Place, Dec. 12, 1855. 



The following translation of a notice which I have just received 

 in Latin from the well-known German malacologist, Dr. Schmidt 

 of Aschersleben, the collaborateur of PfeifFer, Rossmassler, and 

 IMeuke, will, I think, not be unacceptable to the readers of your 

 Journal. At all events, it may direct the attention of British 

 conch ologists to an interesting subject of inquiry, and enable 

 us to decide whether the species in question is henceforth to be 

 considered as British or not. 



I am. Gentlemen, 



Your obedient servant, 



Wm. J. Hamilton. 



Amongst the shells which I have received from the neigh- 

 bourhood of the town of Cheltenham, I have found Clausilia 

 Mortilleti, Dumont. As this shell was published by the author 

 only about two years ago (Bulletin de la Societe d'Histoire 

 Naturelle de Savoie, 1853, p. 78, according to Charpentier), I 

 do not know whether it has yet been noticed by English mala- 

 cologists. The author's specimens, found in the district of Valen- 

 ciennes (Quenoy near Valenciennes, Departement du Nord), at 

 Lyons, at Lowenburg near Bonn, at Schieder near Pyrmont, and 

 at Wolfelsfall in Silesia, have been forwarded to me, as well as 

 the unique specimen from Cheltenham. It is not therefore 

 probable that this species is on the whole confined to a nari'ow 

 district, or that it should live in the single locality alone which 

 we have mentioned in England. In order that we may as soon 

 as possible know more about its distribution, I offer the follow- 

 ing description of it to the notice of English naturalists. 



Clausilia Mortilleti, Dumont. 



T. subrimata, ventroso-fusiformis, coufertim costulato-striata, corneo- 

 fusca, sericea ; anfr. 10-11, convexiusculi, ultimus basi distincte 

 carinatus ; apertura rhomboideo-pyriformis ; lamella iufera pro- 

 funda, ssepe antice ramosa, supera producta cum spiral! juncta ; 

 lunella arcuata ; plica palatalis 1 supera, subcolumellaris vix emersa ; 

 spatium iuterlamellare plerumque plicatulum ; peristoma conti- 

 nuum, breviter solutum. 



Long. 1-1, diam. 4 millim. Apert. 3|^ long., 2^ lata. 



This species is easily distinguished from all those forms which
