SOUTH AFIUCAN MAKINE MOLLUSCA. 205 



Hab. — Congella (H. Eurimp). 



After a careful comparison of South African .specimens 

 witli examples from I'ort Jackson (the types of pulcherrima) 

 I can pronounce with certainty that they all belong- to the 

 same species. It is one of the smallest known forms, and, 

 like some others in this genus, very variable in colour- 

 markings. It was originally described from New Caledonia.
