Patula (Endodonta) perarmata, sp. nov. 



Testa auguste perforata, depresse conoidea, albida, superne 

 rufo macuiata, sub tics rufo irregulariter strigata; an fr act us 6, con- 

 vexi, sub lente accrescentes, costulis tenuibus nutnerosis 

 leviter obliquis instruct/, ultimus hand desce/utens, 

 ad pcripheriam subrotundaius ; apertura obliqua, 

 luuata, tutus /a/net/is circiter decern (tribus subce- 

 qualibus parietalibus prominentibus, una dentifortne 

 supra columellari, circa sex incequalibus palatalibus) 

 instructa; peristoma ieuue, margine columellari 

 dilatato, intus valde incrassato. Diam. mag. 

 3 millim., min. 2§ / alt. 2. 

 Habitat : Diana's Peak (Cutter). 



There are two specimens of this species in the Cumingian 

 collection. They agree in all respects excepting the spire, which in 

 one specimen is considerably less elevated than the other. The 

 three parietal lamella? are about equal, but of the palatal, three or 

 four are larger than two intermediate ones. 



ON CLAUSILIA VESPA, GOULD, AND ITS ALLIES. 



By E. R. SYKES, B.A., F.Z.S., 



Weymouth. 



In the "Journal of the Asiatic Society of Bengal" (vol. xli., p. 205), 

 Dr. W. T. Blandford created the section Oospira to contain Clausilia 

 pliilippiana, Pfr. (as the type), vespa, Gould, bulbus, Benson, and 

 ovata, Blandfd. ; and he also expressed his sense of the difficulty of 

 identifying Gould's species. Mr. F. Stoliczka, in his supplement, 

 redescribed (p. 209) C. vespa, and both he and Dr. Blandford gave 

 figures of what they believed to be that species (pi. ix., fig. 15 and 

 15a). The specimen figured by Mr. Stoliczka is, I believe, one 

 which has been since received by the British Museum from 

 Mr. Theobald. There are two species in the British Museum under 

 the name of vespa, Gould ; one which I regard as really that species 

 from the Hungerford Collection, and the other from Mr. Theobald, 

 which I regard as the species and specimen described and figured by 

 Mr. Stoliczka. What the shell is which is figured by Dr. Blandford 

 as vespa is, the absence of description makes it hard to say ; 

 Dr. Blandford himself says it is hard to separate from philippiana, 

 and it is probably only an elongated specimen of that species. 

 Gould's original description* is very brief;
