The cup is unfortunately broken in the solitary specimen ; but 

 the attachment continues for įrds of the height of the shell, with a 

 very strong rauscular scar at its side. It is distinguished by the 

 close rounded ribs of the exterior and the rich Ariolet of the inner 

 surface.

This most abnormal specimen by itself would never be taken for 

 Cr. spinosum ; nevertheless the intermediate forms in the British 

 Museum Mazatlan Collection, betvveen this and the flat and spiny 

 states, are so gradual and numerous, that I feel compelled to affiliate 

 it to that most variable species.

The shell differs from the non-pitted forms of Cr. imbricatum, 

 Sow. (described as C. dentatum by Mke), in being very much thinner, 

 with the ribs much finer and more numerous. The cup also is not 

 fixed quite so far.

A beautiful young specimen, in the Cumiugian collection, differs 

 from the Pacific form (1) in being thinner, which may be a peculi- 

 arity of growth ; (2) in the want of corrugation of the surface, which 

 may be the result of acid ; (3) in a coloured stripe near the margiu 

 of the cup, which may be an individual idiosyncrasy.
