To this formidable list of synonyms, Dr. Gray adds C. protea 
of D’ Orb. and D’Orbigny adds C. unguiformis, Brod. These 
shells appear however more nearly related to C, nivea, C. B. Ad. 
and C. unguiformis, Lam., to which last, the West Indian 
specimens of C. protea (B. M. Cat. Cub. Moll. p. 33, no. 396) 
probably belong. Some of the specimens marked C. protea 
by D’Orb. are perhaps dead shells of C. onyx. It will be 
observed that this species is distributed under two subgenera
