Hab. Cape Colony, Bedford. 



An imperforate highly polished shell, with very blunt apex 

 and next to no sculpture ; very easily distinguishable from 

 any but the two succeeding species, both of which, however, 

 are larger. 



7. Euonyma platyacme, Melv. & Pons.

 7. Stenogyra beckeri, Fulton, Ann. & Mag. Nat. Hist. xix. p. 154. 



Hab. Cape Colony, Kei Road Bush {Miss Hickey) ; 

 Pondoland (Becker) ; Hog's Back Mountain, Queenstown 

 (Farquhar). 



A large, imperforate, smooth, and very glossy species, with 

 a remarkably obtuse apex, resembling cacuminata, M. & P., 

 but far exceeding it in all dimensions. It possibly attains 

 greater size than that of any specimen yet known to collectors. 



S. btckeri was described by Fulton from shells collected by 

 Dr. Becker in Pondoland, but as the description was published 

 some weeks after that of E. platyacme, it gives place to the 

 latter, which is the same species.

pi. x. fig. 75. 



Hab. Cape Colony, Houw Hoek, Caledon Div. (Purcell). 



Intermediate in size between cacuminata and platyacme, 

 but distinguishable from either by its more convex whorls 

 and the peculiar shape of its columella, which in most speci- 

 mens is very noticeably obliquely truncate at the base, nearly 

 approaching Subidina, though perhaps hardly sufficiently so 

 to cause it to be placed in that genus. It was described from 

 immature shells ; the largest specimen that I have seen
