pronounced, and ttie columella exhibits the same character, but 

 the denticulations there are not so rounded or prominent. 

 Specimens of this species, as of otliers, are sometimes found of 

 a creamy white with a narrow encircling brown band at the 

 suture. In dark coloured shells the white columella, mentioned 

 in Gaskoin's description as distinctive, is very rarely absent.

Obs. — Reeve remarks, "allied to C. puUa in form and general 

 appearance, but it will be found on examination to be obscurely 

 striped, while it has not the white columella distinctive of that 

 species." We think it probable that C. velata, Reeve, Conch. 

 Icon., vol. xi., pi. 28, f. 182, should be united with C. tenebrica, 

 but Reeve does not give the dimensions of C. velata, and the 

 other species figured on plate 28 are much enlarged, this fact is 

 not stated and the usual lines indicating the length of the shells 

 are omitted.
