198 PALEONTOLOGY OF NEW JERSEY. 
side of the whorl, consisting of large ones with several smaller ones between. 
On the upper surface they appear to be more even. 
The cast presents every indication of being of the same species as the 
shells from Claiborne, Alabama, except that it is smaller in size. I see no 
reason, therefore, for separating it under a distinct name. 
Formation and locality: In the upper layer of the Upper Green Mazrls, 
at Shark River, New Jersey. In the collection at Rutgers College. 
Fusus (NEPTUNEA ?) EOCENICUS, n. sp. 
Plate xxv, Figs. 10-13. 
Shell of medium size, depressed-biturbinate in form, exclusive of the 
anterior beak; spire depressed-conical, probably somewhat changed in the 
casts by compression; apical angle about 90° or even more; volutions four 
in number, rapidly increasing in size, and sharply carinate on the periphery ; 
flattened or slightly convex on the upper surface and rather strongly convex 
below; coiled so as to leave the inner ones exposed for only a little distance 
below the carination; aperture large, transverse, angular in the middle and 
extended below in a narrow canal; anterior beak rather slender, its length 
unknown, but being at least as long as the height of the shell above; volu- 
tions marked on the periphery by a series of slight angular, transverse 
nodes, which do not appear below the angulation of the volution and are 
but slightly seen above, being confined principally to the periphery. Sur- 
face of the shell marked by fine spiral strize, those below the angle of the 
whorls being obscurely alternate in size, as seen on the casts. 
This species, as represented in the collection, does not appear to have 
reached a very large size, the largest cast scarcely exceeding an inch and a 
half in its greatest diameter, and the height, exclusive of the beak, has not 
been much greater. The nodes on the periphery are proportionally more 
distinct on the smaller volutions, and much more closely arranged than are 
those on the principal ones. None of the. specimens preserve the beak to 
its full extent; the species somewhat resemble Fusus stamineus Conrad, from 
the Claiborne sands, but the spire has been somewhat more elevated and 
the volution below the carina rounder and shorter, and the nodes smaller 
but more numerous, while the strize are very much finer.
