TUOPHON. 379 



slightly recurved beak, irregularly wriukled by the transverse ter- 

 minations of the ribs ; right lip thickened or sharp, according as 

 it is or is not terminated by a rib ; throat light chestnut-brown, 

 like the exterior of young shells. Length, one and three fourths 

 inches; breadth, four fifths of an inch; divergence, forty-five de- 

 grees. 



Of six specimens in my possession, four belong to Colonel Tot- 

 ten, who kindly sent them to me for description, one was from Dr. 

 J. B. Forsyth of Sandwich, all of which were from the Bank 

 Fisheries ; and one was taken from a fish caught in Massachu- 

 setts Bay by Mr. Coutliouy. Halifax ( Wil/is} ; fossil, Montreal 

 (^Dawson} ; whole coast of Greenland (^Hai/es) ; Belfast Bay. 



This shell is remarkable for its sharp elevated ribs, as if the sur- 

 face were raised by flakes arranged like the ribs on most species of 

 Scalaria. It is very much like the Fusus Bamffius^ but, on the 

 whole, I think it is different, inasmuch as we have that species with 

 its undou!)ted characters, and the two never seem to run into each 

 other. The large figure of Donovan ('' Brit. Shells," pi. 169, fig. 1), 

 given as Marex Bamffiiis^ represents our shell. 



It is allied to M. Magellariicus ; and the figure in " Encyc. 

 Meth." pi. 438, fig. 4, referred to as M. Ij/ratus, Lamarck, bears 

 a distant resemblance to it. 



Trophon muricatus. 



Shell slender, yellowish ; whorls very tumid, with about ten conspicuous folds 

 and elevated revolving lines; beak long and straight.

Fusus muricatus, Brown, Conch, of Great Brit. &e. 48, fig. 28. — Gould, Inv. 1st ed. 

 293. 



Shell elongated, slender, yellowish-white, or orange, composed of 

 seven very convex whorls, the suture deeply defined, forming an 

 elevated, pointed spire ; these are traversed by about ten broad, 

 rounded folds or undulations which are crossed by coarse, elevated, 

 revolving, glossy lines, producing a rough, granulated, almost tuber- 

 cular surface ; aperture broad oval, terminating in a long, straight 

 canal, which together equal half the length of the shell ; outer lip 

 rendered jagged by the revolving lines, and sometimes greatly thick-
