336 CLAUSILIID^. 



as regards outline, it fits Blanford's figui'e (fig. 15) better than 

 Stoliczka's (fig. 15 a) but in the former the striae appear more 

 distant, and it shows rather more sinus at the upper parietal fold.

Original description : — " T. solida, sinistrorsa, vesppeformis, 

 deflecta, Isevis, intense rufa : anfr. 6, anteriori raptim attenuate, 

 proximo corpulento apicalibus cito descrescentibus ; sutura im-

 peritremate late reflexo, rufo.

Mr. Sykes, as already stated under C. stoliczJaina, has pointed 

 out that the shell described and figured by Stoliczka and Blanford 

 as 0. vespa — which he believes has been received by the British 

 Museum from Mr. Theobald — difiers in several respects from 

 Gould's species, and he regards it as a new form. On the other 

 hand a shell in the British Museum, from the Hungerford col- 

 lection, he believes to be the true vespa and adds a diagnosis, 

 based upon this specimen, to supplement the very brief description 

 by Gould. His diagnosis is as follows : — 



" CI. testa solida, sinistrorsa, fusiformis, medio inflata, apex 

 obtusiuscula, subtile et indistincte decussata, hand nitida, intense 

 rufa, ad apicem pallidior ; anfr. 6, apicales cito decrescentes, 

 penultimus et ante penultimus inflati, corpulenti ; sutura impressa 

 vix marginata ; apertura ovata, peritremate late et valde reflexo, 

 rufo ; lamella superior valida, obliqua, rufa, fere ad marginem 

 attingens, 1. inferior valida rufa subparallela ; plicoe palatales 5-6, 

 suprema (principalis) longa, secunda brevior, descendens, reliquie 

 parvae, subaequales descendentes. 



"Alt. 27 millim., lat. 8 millim. ; apert. alt. 7 millim., lat. 

 5 1 millim, 



'" CI. vespa, Gould, must be withdrawn from the Oospira 

 section both on the ground of shape and its sculpture (an indis- 

 tinct decussation) and CI. stoliczkana should take its place."

Through the courtesy of Dr. John M. Clarke, the Director of 

 the State Museum of Albany, N.T., I have been able to examine 

 one of the two specimens of Gould's C. vespa, and I am in a 

 position to confirm Mr. Sykes' surmise that the shell figured as 

 vespa by Stoliczka is quite different from Gould's species. The 

 specimen sent to me by Dr. Clarke is smaller than the one in the 

 Hungerford collection, figured by Mr. Sykes, measuring: length 25,
