Zoology, Cambridge. Type of rhysodes in British Museum ; tabula 

 in Ecole des Mines, Paris. 



Hab. CAPE OF GOOD HOPE. Near Newlands (Benson). Table 

 Mountain (tabula, Chaper). ? Port Elizabeth (fide Sturany). Widely 

 distributed throughout the Cape Peninsula from Table Mountain to 

 ' Cape Point. 



The type of rhysodes, from the Layard collection, from an unknown 

 locality, is identical with perplicata, Bs. ; and after careful study of 

 Chaper's description and figure of tabula, I have no hesitation in 

 placing the latter in the same synonymy.

Hab. NATAL (Wahlberg). 



No recent localities are given, as doubt exists whether the shell, 

 which has of late years been generally accepted as pinguis, is in 

 reality that species, von Martens' record of Tette must also be 

 viewed with distrust.
