Jur. Foss., p. 22; Fusus ? (Gabb) Geol. N. J., Newark, 1868, p. 730. 
Shell of medium size, ovately biturbinate, of nearly equal length above 
and below the point of greatest diameter; spire obtusely conical, giving an 
apical angle of about 50°; volutions probably about five in the shell, 
ventricose, with deep sutures, the last one subangular on the periphery 
and presenting a pyriform shape when considered without reference to those 
above, the lower part being somewhat attenuated; aperture large, elongate, 
subelliptical, more rounded externally than on the inner side; columella 
large and strong, as shown by the cavity left by the removal of its sub- 
stance in the cast, smooth, and probably pointed below; volutions marked 
by numerous obliquely vertical folds, strongest on the largest part; surface 
features unknown. 
This species is closely related to P. erraticus n. sp., herein described, 
but differs materially in its more distinctly ventricose and more pronounced 
volutions, and apparently in the greater number of vertical folds crossing 
them. Mr. Gabb’s type specimen had nearly the form and size of that 
here described, so nearly so that not the least doubt exists of their specific 
identity; but the generic relations appear to be undoubtedly with Pyrifusus. 
Formation and locality: Mr. Gabb’s type was from Mullica Hill, New 
Jersey, while our specimen is marked as coming from Freehold, New Jer- 
sey. Both specimens would appear to have come from the Lower Green 
Marls.

Shell below a medium size, short-conical or subglobose, shorter below
