 slightly wavy, brown stripes. "Whorls 8-9, rather convex, 

 rather coarsely granosely sculptured; suture between upper

 descending, smoother upon the lower part. Aperture sub-

"The granose surface of this species is the result of the 

 coarse raised lines of growth being crossed by transverse 

 impressed striae, which being somewhat remote from one an- 

 other cause the granules to assume a rather elongate form. 

 Mr. Alfred E. Craven informs me that the distinguished 

 name of Dr. Kirk has already last year been associated with 

 a species of this genus. Such being the case, I am com- 

 pelled to alter the designation originally applied to this 

 species; and therefore I have much pleasure in substituting 

 that of A. craveni' (Swilli).
