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-grenlandicus of Chemnitz.

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. 
Scalaria multistriata. Say, Jour. Acad. Nat. Sciences, Vol. 5, p. 208. 
S. id. Ip. American Conchology, pl. 27. 
SS id. Gou.p, 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.
