The spiral ridges are crossed by oblique shallow sulci so as 

 to produce a somewhat beaded appearance.

C. contractum and C. tasn latum, regarded as species in 

 the 'Marine Shells of S. A.,' p. 35, are not, in my opinion, 

 worthy of even varietal rank. Both names were preoccupied, 

 the former by Bellardi for a fossil species, and the latter by 

 Quoy and Claim ard. The name C. crumena was proposed 

 by Bayle in 1880 for Sowerby^s C. contractum. 



The species has a wide range. Adams quoted it from the 

 Philippines, and there are specimens from Muscat and the 

 Persian Gulf in the British Museum.

Hab.— Port Alfred. 



The specimens quoted under Cerithiopsis purpurea 

 Angas (' Marine Shells S. A.,' p. 27) appear to belong to this 

 species. I am doubtful at present whether any constant dis- 

 tinctions between the two species can be pointed out.
