This may possibly be a small variety of the preceding 

 species. 



18. Cyclostoma anceps, Martens? 



Hab. Hlali, Htoni Hiranza, Hkata, Kirassa. 



None of the specimens from the above localities are quite 

 so large as the shell figured by Martens (Monatsb. Akad. 

 Wiss. Berlin, 1878, pi. i. fig. 4). In other respects they 

 appear to agree with the description. The largest specimen 

 has a greatest diameter of 22 millim. 



19. Cyclostoma, sp. 



Hab. Kidete [Emin)] Usagara [Hanmngton) . 



A small species, about 12 millim. in diameter, with a few 

 lir£e in the umbilicus and others upon the spire and upper 

 part of the last whorl. Of about the same shape as the pre- 

 ceding species.

Hab. ? [Emm) ; Lake Nyassa and between it and the 



east coast [T1iompso7i). 



The precise locality where this species was collected is not
