238 PALEONTOLOGY OF NEW JERSEY. 
inch in length, with a transverse diameter at its widest point equal to about 
one-half the length, the specimen being very slightly compressed. Spire 
elevated, three volutions being preserved in the cast above the body whorl, 
yolutions ventricose, rounded, the last one measuring about three-fifths of 
the entire length; aperture elongated, elliptical in outline; columella mod- 
erately long, curved, marked by a single fold in its lower part. Surface of 
the cast marked by proportionally strong impressed lines, leaving rounded 
ridges between; no evidence of puncte in the lines can be detected, either 
on the cast or in the matrix, although they may have existed on the shell. 
This species is rather uncommon in the marls of New Jersey, for 
among all the shells and casts of this formation which have come under 
my observation only a single specimen, and that the type used by Mr. 
Conrad, has been observed. It is readily distinguished from any of the 
Cretaceous species by its general form and height of spire. Mr. Conrad 
did not remove the specimen from the matrix, consequently did not find the 
fold on the columella, and referred it to his genus Acteonema. (See obser- 
vations on that genus.) 
Formation and locality: In the stony layers at the top of the Upper 
Green Marls (Eocene), at Shark River, New Jersey. Rutgers College col-

Shell of medium size, ventricose or broadly ovate in outline, spire 
short, the outer volution forming the principal part of the shell; volutions 
about four in the cast, rounded, with distinct sutures; aperture rather large, 
more than half as long as the entire shell; columella short, apparently 
straight and marked by two distinct and rather distant folds, one at the 
base, the other near its upper part; surface of the shell and cast marked by 
strong, impressed, spiral strize, with rounded ridges between. There appears 
to have been puncte in the depressed lines, but the evidence of this is not 
quite satisfactory.
