I cannot separate this form from the subfossil ones from Celebes. The sculpture of these 

 latter seems to be sharper, but this may depend on its fossil state or on local influence. The 

 recent specimens are dark yellowish-brown, mottled with white, mixed with irregular patches of 

 crimson on the last whorl; the aperture especially the columella and canal is stained by the 

 same colour.

1 have omitted the quotation of Kiener's work, as his figure represents a shell from 

 Senegal described as C. punctahim by Bruguiere. Reeve and Tryon think they are synonyms, 

 Kobelt that they are different.
