 The general aspect and sculpture of this shell apjn-oaches 



nearest to that of C. cnnaliculaia, from which it diifers in 



not having the deep broad channelled groove around the 



sutures, whilst the coloured squares arc more (bstant, 



darker, and more defined.

The tuberous Helmet. Shell large, triangularly ovate, 

 very hump-backed, spire flatly convex, sharp at the 

 apex ; whorls one-varicose, angulated roiiiul the 



uppei- part, tubercied, central dorsal tuljercle more 

 prominent than the rest, witii three obsoletely tuber- 

 cied callous belts, interstices transversely grooved 

 and longitudinally very closely lineated in a some-

This species is mainly distinguished by its swarthy liue 

 and solid triangular growth, the back of tlie shell being 

 peculiarly gibbous and strongly tubercied.
