The two series of acute red nodules at once distinguish this species 

 from all the other South African forms. The pustules beneath the 

 suture and those upon the lower part of the body-whorl are quite small 

 and close-set, some being white and others red. The fine spiral sulci 

 and intervening lirae with which the entire surface is sculptured, are 

 visible even to the naked eye. The tigure of C. nigro-punctatum 

 Sowb. (Thes. Conch., vol. ii., p. 860, pi. clxxx., fig. 97) is very like 

 this species.
