2. Cdpulus militaris. Military-Bonnet Capulus. 



Shell conoidal, rather thick, decussated with longi-

A small individual, only a twelfth cf 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- 

 lated, white, glossy on the apex ; the inside also white.

A small individual, two-twelfths of an inch in height, and 

 nearly the same in the diameter of the aperture, was found by 

 me in a cavity among Serpula?, on a dead shell of Fusus anti-
