perfect, the shell is covered with a pilose yellowish or brownish

 striato-sulcate, with some concentric rugae ; the exterior red- 

 dish-white or pink ; the inside highly glossed, and reddish, or 

 yellowish, or white. Diameter about an inch, height three-

2. Capulus militaris. Military -Bonnet Capulus. 



Shell conoidal, rather thick, decussated with longi-

A small individual, only a twelfth of an inch in diameter, 

 found by me among shell sand, from Ugie-mouth, sent by Mr.

 form, suddenly tapering to a long slender point, which is in- 

 volute and turned considerably to the right ; the surface reticu-

 quus, sent from Banff, by Mr. John Clark, in the end of De-
