126 NEW-YORK FAUNA MOLLUSCA. 



This species was first detected by Mr. Couthouy in the stomachs of fishes off the coast of 

 Massachusetts, and subsequently along the shores. It is a boreal species, which will proba- 

 bly be found on our own coast. On the authority of Mr. Sowerby, this species has been 

 referred to the Turbo clathrus-grcenlandicus of Chemnitz.

•S. id. Godld, Invertebrata of Mass. p. 250. 



Description. Shell elongated, conical. Whorls seven or eight, rounded ; body-whorl with 

 an elevated revolving line, which is lost in the sutures above ; from sixteen to eighteen robust 

 obtuse ribs. Aperture subcircular, with a strong rounded lip, which is more dilated at the 

 base. No umbilicus. 



Color. White or brownish, with one or more revolving bands on the body-whorl. 



Length, 0"5. Width, 0'2. 



This species, together with the following, have been found from the coast of the Southern 

 States to Massachusetts. I am not aware that it has yet been observed on our own coast. 

 The northern specimens appear to be less robust, and with more delicate ribs than those 

 noticed by Mr. Say. 



Scalaria multistriata.

5. id. Id. American Conchoiogy, pi. 27. 



6. id. Gould, Invertebrata of Mass. p. 251. 



Description. Shell solid, tapering to an acute apex. Whorls eight, very convex : suture 

 distinct; ribs regular, equidistant, varying from fourteen to twenty in number, and obsolete 

 on the three terminal whorls : the spaces between the ribs with numerous fine revolving lines. 

 Aperture oval, margined by a rib. Umbilicus none. 



Length, 0'5. Width, 0"15. 



The northern and southern specimens of this shell exhibit some differences, but scarcely 

 sufficient to warrant the creation of a new species.
