SOWERBY : MARINE SHELLS OF SOUTH AFRICA. 7 



long ; compared with M. hulbus it is of lighter growth, 

 the longitudinal lines are broader and more distant, and a 

 sharp prominent keel crosses the columella. 



Eburna papillaris Sowerby. — This very rare species has not 

 yet been discovered in perfect condition. 



Separatista grayi A. Adams. — A very curious shell, rarely 

 found. 



Ancillaria obtusa Swainson, — A very remarkable, and, when 

 in good condition, handsome species. 



A. obesa Sowerby. — This pretty little species seems to be 

 plentiful at Port Elizabeth, but as is the case with most of 

 the species, perfect specimens are not so common. 



A. lineolata A, Adams. — Not common. 



A. cinnamomea Lamarck. — Generally smaller than the Red 



Sea specimens. 

 Triton doliarius Lamarck. — A well-known, but curious 



species, having as much the appearance of a Dolium as of 



a Triton. 



T. africanus A. Adams. — Although of very different ap- 

 pearance, I strongly suspect that this belongs to the same 

 species as the last ; the upper whorls are identical, but the 

 last whorl is elongated and without spiral ribs. In one 

 specimen before me the strong raised spiral ribs reach a 

 varix just after the commencement of the last whorl, up to 

 which point anyone would pronounce the shell to be 

 Triton doliarius, after which its character is entirely 

 changed. 



T. klenei A. Adams. — A species allied to the AustraUan 

 T. exaratus (Reeve). 



T, nodiferus Lamarck. — Of rather more compressed form, 

 a,nd with more clouded markings than the Mediterranean 

 species. I think that to separate Reeve's T. saulice from 

 this species, is to draw too fine a distinction.
