98 MARINE SHELLS OF SOUTH AFRICA. 
entum crassiusculum; cardo arcuatus, planulatus, latus; 
dentes 18, plus minusve elongati, rectiusculi; pagina interna 
alba ; impressiones musculares vivide rufo-fusco radiatim 
tincti ; marginibus valde crenulatis. 
Antero-post. 65, umbono-marg. 65 m.m. 
Hab. Durban. 
This shell is quite distinct from the Mediterranean 
species, and the vivid colouring of the muscular impressions 
appears to be characteristic, although having only seen one 
perfect specimen and two or three odd valves, I cannot with 
certainty pronounce the character invariable.
