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

 striae, 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 ovate-conic, ventricose, thin ; whorls six or eight, tome- 

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

 clouded with brown ; epidermis hispid.

Tritonium ciliatum, O. FABR. ; Fauna Grcenl., 401. 



Buccinum ventricosum, 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 very oblique, obscure fold. 

 Length 2 inches, breadth 1 T \ 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, " ciliatus pilis brevibus" as he describesjt. Nor is 

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

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