Hah. The Island St. Thomas {%werlnj) ; Mossamedes, 

 Angola [in colJ. J. R. Le B. Tomlin). 



This, the largest s[)ecies and the type ot" the genus, is 

 distinguishable at a glance by the whorls being flattened or 

 ciiannelled above in such a remarkable manner. 



The geographical distribution of tliis species has hitherto 

 been uncertain, since the only localities quoted were "The 

 Island St. Thomas" (Soioerb//) and Japan {Kobelt*). 

 Mr. Tomlin has a specimen, with the operculum, from 

 Mossamedes in Angola, which he obtained direct from that 

 place. It therefore seems fairly certain that Sowerby's locality 

 was the St. Thomas Island in the Gulf of Guinea, and that 

 Kobelt was wrong in quoting Japan. 



In the third edition of Argenville's * Conchyliologie ' 

 (1780), pi. xl. fig. J 3, this species is figured, with forms of 

 Terebra, Cerithium, &c., merely under the general term 

 " Vis'-' (screw-shells).
