DESCRIPTIONS OF NEW SPECIES OF SOUTH 

 AFRICAN MARINE SHELLS. 



By EDGAR A. SMITH. 



(Read before the Society, June 14, 18 

 (Plate V.). 



Several papers on the molluscan fauna of South Africa, by Mr. 

 G. B. Sowerby, which appeared in this Journal, 1 were subsequently 

 embodied in his separate publication, entitled " Marine Shells of 

 South Africa." The present short paper may be regarded as a 

 supplement to that work, and it is proposed to issue from time to 

 time further appendices referring to some omissions and errors 

 which have been noticed. Mr. Sowerby having through pressure of 

 business decided to abandon further work upon this subject, Mr. 

 J. H. Ponsonby very kindly placed the material received from his 

 correspondents at my disposal, and has also presented to the British 

 Museum a very valuable collection of South African shells got 

 together during recent years. To Mr. H. Burnup and Mr. F. 

 Quekett we are especially indebted for so energetically forwarding 

 the results of their collecting.

Nab., Table Bay, 10 fath. (Lightfoot). 



There is a very faint indication of a second pallid zone around 

 the upper part of the body-whorl and the middle of the upper volu- 

 tions. It is very closely allied to T. tristis Desh., but is rather 

 stouter, has stronger costas and natter whoris, the last being some- 

 what quadrate. The coloration also is different.

 nigris ad ?nedium anf /actus ultimi interruptis picta, infra suturam
