 single intermediate lirse, in the middle of each whorl a few of the

Differs from the preceding species in its finer, more regular spiral 

 sculpture, variegated coloring, and absence of tubercles : it is possi- 

 bly only a variety of it. C. nitidum, Sowb. (fig. 54) = gentile, 

 Bayle, and fC. baccatum, Hombr. et Jacq. (fig. 59), are synonyms. 



Var. LUCTUOSUM, Hombr. et Jacq. Fig. 56.

Shell Avith rounded longitudinal jilications, varicose, slightly nod- 

 uled by spiral sculpture ; yellow'ish brown, with regular chestnut or 

 chocolate spiral lines. Length, 22 mill. 



Hub. unknown. 



C. rubrolineatum, Sowb. (figured), is precisely like Hanleyi, — 

 which was first described of the two on the same page of the 

 Thesaurus. Why Sowerby abandoned the latter name in favor of 

 the former, I cannot imagine.
