Shell of medium size, ovately bituvbinate, of nearly equal length above 

 and below the point of greatest diameter; spire obtusely conical, giving an 

 apical angle <»f 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. erratieus 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. Grabb'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. Grabb'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.
