SOWERBY : MARINE SHEiLLS OP* SOUTH AFRICA, 151 



Marginella Savignyi Issel. A minute species hitherto only 



known to inhabit the Red Sea. 

 M. neglecta Sow. The original type is a worn colourless shell, 



but the South African specimens are subpellucid and banded 



with brown. I have had similar specimens from Mauritius. 

 M. cylindrica Sow. The type of this species is also a white 



worn shell. The South African specimens are subpellucid, 



and marked with pale brown peculiarly interrupted trans- 

 verse lines. 

 Columbella pulchella Sow. Only dead specimens of this 



well-known West Indian species have been found at Port 



Elizabeth. 

 C. cereal is Menke = C. Xraussii Sow. 

 C. flava Brug. Common in the Indian Ocean generally. Only 



a few worn specimens found at Port Elizabeth. 

 Natica didyma Philippi. This species seems almost universal, 



extending eastward to Australia, and northward to Japan. 



I have also seen specimens from the eastern Mediterranean 



mixed with JV. oUa. 

 Nerita sanguinolenta Menke. This species I have also had 



from Mauritius, but it does not seem very common either 



there or at the Cape. 

 Terebra pertusa Born. A young worn specimen is at present 



the only evidence of this species belonging to the Cape fauna. 

 Chemnitzia castanea Carp. Three specimens fairly perfect. 

 Cingulina circinata A. Adams. 

 Syrnola aciculata A. Adams. 

 Rissoa fenestrata Krauss. This species differs very slightly 



from the British and European R. calathus, of which I am 



inclined to think it a variety. 

 R. pinnas Krauss. Several specimens of this rather curious 



species have been found at Port Elizabeth. I have never 



seen it from any other locality. 

 Solarium cingulum Kiener. Of this species I have only 



seen one rather small but richly-coloured specimen.
