 form of an Erato. The specimens from Port Elizabeth 

 scarcely differ from the Australian. 



Marginella inconspicua Soiverby. — A small white sub- 

 pellucid species, somewhat like M. alabaster, but much 

 smaller. 



Columbella sagena Reeve. — A species of very wide distri- 

 bution, but seldom found on the South African coast. 



Natica imperforata Sowerby. — Reeve's JV. genuana belongs 

 to this species. 



Natica (Ruma) Simioe Chemnitz. — Not uncommon in the 

 Indian Ocean, but rare at the Cape.

Solarium (Torinia) variegatum Gmelin. — Common in the 

 Indian and Pacific Oceans. 



Terebra cingulifera Lamarck. — One small worn specimen. 

 Common on the Mauritian coast and in various other

 of each of the two striking varieties of this rare and in- 

 teresting species.

A characteristic species, spotted something like C. eburneus, 



and presenting some similarity to the West Indian C. leouinus 



and spurius. It is closely wave-striated towards the base, 



which is conspicuously tinged with brown. I have as yet 



seen only a single specimen of this species.
