MIOCENE MOLLUSCA AND CRUSTACEA. Lil? 
~ 
This shell somewhat resembles Pleurotoma flecuosa Emmons, Geol. Surv. 
N. Carolina, 1858, p. 265, fig. 148, but is much more slender in proportion 
to the entire length, besides being covered with spiral lines, of which there 
is no mention in the description of that species. 
Formation and locality: In the gray Miocene marls at Shiloh, N. J. 
From the collections of the National Museum.

“Shell subfusiform, transversely striated, with oblique longitudinal ribs; 
upper part of the whorls concave and plain.” 
A single imperfect individual, referred with some doubt to this species, 
is among the collections from Jericho, N. J. The shell is quite small, still 
somewhat larger than the figure given by Mr. Conrad; the spire has been 
acute, the volutions somewhat convex, with a strong concave constriction 
at the upper part, and are longitudinally plicated; plications about eleven, 
rounded and distinct. Aperture elongated and narrow; beak moderately 
long; inner lip not callous; entire surface of the shell below the constric- 
tion marked by fine, rather even, raised, spiral lines with flat interspaces. 
Formation and locality: In the gray sandy marls of the Miocene at 
Jericho, N. J. From the collection of the National Museum.
