SOWERBY : MARINE SHELLS OF S. AFRICA. 7 



first thought it might be specifically distinct, but there 

 seems to be no character besides the grooves by which to 

 distinguish it, so I propose to call it variety sulcata. 



Pleurotoma Fultoni Soiverby, Proc. Zool. Socy., 1888.— 

 This species, described and figured for the first time this 

 year, has long been known to me, but the specimens were 

 so defective that I thought it best to wait for a more nearly 

 perfect one before attempting to describe the species. It 

 is about an inch long.

Purpura (Vexilla) vexillum Chemnitz. — This species, the 

 type of the little group for which Swainson proposed the 

 generic name of Vexilla, is very rare at Port Elizabeth, but 

 not uncommon on the Mauritian coast; it is also said to be 

 found among the Pacific Islands. 



Triton (Epidromus) nitidulus var. Sotuerby. — A single 

 specimen of this species has been sent to me by Mr. 

 Bairstow, from Port Elizabeth. It differs from the typical 

 form found on the Mauritian coast in being more distinctly 

 granulated. I was at first inclined to consider it distinct, 

 but find the species liable to considerable variation. 



Ranella granifera Lamarck. — One small specimen.
