sixteenths of an inch broad where broken. Figures of the specimen are 
given to aid in its identification, although so highly imperfect. 
Formation and locality: In the upper layers of the Upper Green Marls 
at Shark River, New Jersey. From the collection at Rutgers College.

Shell large, heavy, and apparently ponderous. Spire elevated and 
strong, the apical angle on uncompressed specimens being about 45° or 
50°; volutions about seven, strong, subangular above the last one, which 
is biangular, the lower angle being concealed on the others by the volu- 
tion below; each volution marked by a series of twelve strong, rounded, 
node-like vertical ridges along the angle, and dying out below at the suture 
line; periphery of the last volution vertical between the angles, and rap- 
idly contracted in the lower part to form the long, comparatively strong 
anterior beak, which is nearly or quite as long as the height of the spire 
above the middle of the last volution; columella straight to near its extrem- 
ity. Only a single, rather slender, oblique fold has been observed on any 
of the many specimens examined. Aperture comparatively small, wider 
than high, subangular at the upper outer part and rapidly rounded inward 
to the beak and narrow canal below; surface, as indicated both by the casts 
and matrix, covered by low spiral strize, those crossing the tops of the 
nodes being the strongest and most distant; those on the lower part of the 
body volution are not distinct enough on any of the casts to reveal their 
true character. | 
This shell has been very closely related to some forms of the living 
shells referred to Fasciolaria trapezium Linn., and very closely resembles 
that known as F. Audouint Jonas, usually found in collections under the 
first nanied species. The spire is, however, somewhat more elevated than 
in that one, and the anterior beak somewhat more slender. The single
