broad chanael in the mug-like expansion of the lip. The longi- 

 tudinal ribs are nearly white, between which the brown coloui-iug 

 is partly disposed in transverse linear streaks.

 Hah. East Africa ? (ex coU. Keen). 



A prettily painted shell, with a smooth shining surface. The 

 ribs are ^^•hitish, crossed on the upper whorls with one and on the 

 body-whorl with two brown zones ; the interstices between the 

 ribs are entirely brown. The suture is covered with a whitish 

 callosity. 



It may be doubted whether this species is rightly placed in the 

 section or subgenus Surcula, but to judge only from the shell, and 

 to propose a new section for it, would be only to add to the already 

 far too numerous ill-defined subdivisions.

Hah. Hong Kong. 



A shell of simple character. I place it provisionally, but with 

 some doubt, in the section Clavus, which may or may not prove to 

 be clearly separable from Drillia.
