308 MR. E. A. SMITH ON THE [Apr. 1 



general colour of the shell appears to be brown or reddish, but on 

 close examination it will be seen that the spiral striae are whitish, 

 and the interstices or lirae only are coloured. 



Pleurotoma (Mangilia) casta, Reeve. 



The single shell collected by Capt. Turton agrees in many re- 

 spects with the type of this species, which, unfortunately, is in rather 

 bad condition, and only exhibits faint indications of spiral striae. 

 The specimen from the " Sea-horn " is beautifully striated, is rather 

 shorter, and has one costa less than the type. Nevertheless, I have 

 a strong behef that it belongs to the same species. The locahty of 

 P. casta was unknown to Reeve.

This seems to be rather a common shell on the South-African 

 coast. C. fulminea was described from Simon's Bay, Krauss 

 cites the Cape Coast for it, and in the Museum there is a series 

 labelled Natal. Two specimens only, of a rather dark tint, were ob- 

 tained at St. Helena.

A sn:all shining pinkish-brown shell, exhibiting a few spiral pale 

 stripe. The penultimate and antepenultimate volutions show indi- 

 cations of longitudinal plication.

Hah. Cape of Good Hope and Natal coast {Krauss and others) ;

Only one voung sj ecimen of this common South-African species 

 was sent by Capt. Turton. The locality given by Reeve (Con. Icon, 

 sp. 48), " Tigre Bay, Abyssinia," requires confirmation. It may be 

 correct, but the number of species common to South Africa and the 

 Red Sea is not large.
