SYKES : ON THE IDENTITY OF CLAUSILIA MOUHOTI. 



167 



The Hungerford specimen is from Hooden Koo, Salvvin Valley, 

 Burmah ; Gould's type from " Tavoy." 



CI. vespa, Gould, must be withdrawn from the Oospira section 

 both on the ground of shape and its sculpture (an indistinct decus- 

 sation) and CI. stoliczkana should take its place. 



ON THE SPECIFIC IDENTITY OF CLAUSILIA 

 MOUHOTI, PFR., AND C. MASSIEI, MORLET.

The late Com. Morlet has described * as a new species a shell 

 which I consider identical with C. mou/ioti, Pfr.f I have carefully 

 compared the descriptions and figures of the two species and have 

 also examined the types of C. mouhoti. The only differences which 

 appear to exist are that in C. massiei, Morlet mentions a "plica 

 columellaris" and does not mention the occurrence of any lamella 

 subcolumellaris. The only conclusion to be come to is that Morlet 

 was partly using the old nomenclature of Moquin-Tandon and 

 Dupuy ; if this is so the two are the same thing and the matter is 

 much simplified. It is to be regretted that authors will not use 

 modern terminology in such matters ; the most to be recommended 

 is that of Messrs. Smith and Woodward, | adapted from Boettger, 

 Westerlund and Moellendorff. The length and breadth of the shells 

 as given by Pfeiffer and Morlet are identical ; the whorls in both 

 cases are given as twelve ; they are both from Laos. Both have 

 a lamella, superior and inferior, and judging from the figure of 

 massiei both are similarly situated. C. massiei has a lamella inter-
