SOWERBY: marine shells of south AFRICA. 373 



A simple conical shell with an obtusely-keeled margin. 

 It somewhat resembles G. capensis, but is much more ele- 

 vately conical,

Unfortunately I have only the shell of this species, so 

 that it is impossible with certainty to establish its generic 

 position ; the form of the shell, however, leaves little room 

 for doubt that it is a true Voivatella. Compared with V. 

 aaningii it is much smaller, less abruptly truncated and 

 produced posteriorly, and proportionately wider anteriorly; 

 it is also less cylindrical in form than V. cincta of Neville, 

 and shows no sign of the transverse bands characteristic of 

 that species.
