form, which is more or less inflated, sometimes the folds, then the 

 strife, and then both, disappearing. And were specific names to be 

 given to every considerable variety, the nomenclature would be most 

 unscientifically burdened. 



The figure of Kiener, and the wood-cut in Drummond's " Let- 

 ters," &c., are accurate representations of our shell. 



Bu/CCINUM CILIATUM. ^ 



Shell ovote-conic, rentricose, thin ; whorls six or eight, some- 

 times folded at the suture ; sjnrally striated, ash-colored, or 

 clouded with broivn ; epidermis hispid.

Tritonium ciliatum, O. Fabr. ; Fauna Grainl., 401. 



Buccinum ventricosuin, Kiener ; Species, (Buccinum,) pi. 3, f. 7. 



Shell similar to B. undatum, but thin, paper-like, and destitute 

 of folds, except short ones near the suture, so as to give that part 

 a crenated appearance. The whorls are more convexly rounded, 

 so as to be nearly cylindrical ; surface with minute and close re- 

 volving lines, color yellowish, or livid, most specimens with 

 blotches, or dashes of brown ; epidermis fawn-colored, and hispid 

 with short hairs, arranged for the most part along the lines of 

 increase. Aperture short, rounded, lip very thin ; throat pure 

 white, or yellowish. The pillar has a vfery oblique, obscure fold. 

 Length 2 inches, breadth lj\ inch, divergence 58°. 



Taken from fishes caught, for the most part, at the Banks. 



The thin structure, inflated form, and want of undulations, distin- 

 guish this species from the preceding. It agrees very accurately 

 with the description of Fabricius ; and Dr. Loven assures me that 

 there can be no doubt of its being his T. ciliatum. As the epidermis 

 is often removed, or rubbed, however, we do not always find it fringed 

 with short hairs, " c.iliatus fills hrevihtis,'''' as he describes it. Nor is 

 it less doubtfully the B. venfricdsiim of Kiener, although we do not 

 often find it clouded with blotches, or zigzag stripes, as he figures it.
