Original Description (from Say, 1822, p. 231):

"Shell cancellate, ventricose, cinereous or pale reddish-brown, with two or three irregular, sometimes obsolete darker fascia; body whirl with twelve thick, prominent costa, and about as many revolving filiform lines, which are not much elevated, and but simply crenate the costa and lip; labrum incrassated, with about two more prominent teeth within; labium callous; spire short, rapidly attenuated to an acute tip.

Length three-fifths of an inch.

Inhabits the southern and middle coast.

Cabinet of the Academy and Philadelphia Museum.

Rather rare. I found but four specimens. For the locality of the coast of the middle states, I am indebted to my brother, Mr. B. Say, who brought me a specimen from the shores of New Jersey."
