ON SdUTH AFRICAlvf MARINE SMELLS, WITH 

 DESCRIPTIONS OF NEW SPECIES. 



By EDGAR A. SMITH. 



(Read before the Society, June i2tli, 1901). 



(Plate I.). 



It was proposed in a former paper^ to issue from time to time others 

 dealing with the marine mollusca of South Africa. Through the 

 energy of Mr. J. H. Ponsonby, who has got together from his South 

 African correspondents the material upon which the present paper is 

 based, I am enabled to make a first fulfilment of that proposal. Speci- 

 mens of nearly all the species described or referred to, are in the 

 British Museum, having been presented by Mr. Ponsonby.

Hab.y Mossel Bay, Cape Colony (J. Crawford). 



Quite distinct from Fissurella fimbriata of Reeve, with which it was 

 confounded in the " Marine Shells of South Africa." It is a longer 

 and narrower and more depressed species, with the foramen much 

 less central. The sculpture is very similar, although not absolutely 

 identical. The edge of the interior is much less deeply notched than 

 in F. fimbriata, which exhibits a fine radiating striation within, which 

 is less observable in the present species.
