Jlab. Senegal. 



Of precisely the same typical character as C. cancellata, 



from which species it difi'ers specifically by its uniformly 



smaller size antl finer sculpture.

Hab. Island of Ticao, Philippines (dredged from sandy 

 mud, at the depth of six fathoms) ; Cuming. 

 This fine species differs from the G. asperella, to which 

 M. Deshayes refers it, in being of a more acuminately fusi- 

 form growth, more elegantly sculptured, and in not being 

 excavatclv cliaiiiielled at the suture.

 ovate, somewhat fusiform, imperforated, here and 

 there varicose, twisted at the base, spire rather short, 

 sharp, whorls convex, obliquely ribbed, cancellated 

 with narrow spiral ridges ; whitish, variegated with
