Mountain (tabule, 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 tabulg, I have no hesitation in 
placing the latter in the same synonymy.

No recent localities are given, as doubt exists whether the shell, 
which has of late years been generally accepted as pinguwis, is in 
reality that species. von Martens’ record of Tette must also be 
viewed with distrust.
