GASTEROPODA OF THE EOCENE MARLS. 207 
form of the columella and canal can not be determined, as this part of 
the cast is imperfect; but the length as preserved is over 4 inches, with 
a diameter of the body volution of nearly 2? inches; but the imprint of 
the oblique folds is very strong, and for the size of the shell have been 
proportionally very large and heavy, broad and rounded. The specimen 
has been compressed in such a manner as to contract the aperture and pre- 
vent a satisfactory view of it being given in a figure; but the general 
form is so characteristic that there can be no difficulty in recognizing it. 
Formation and locality: In the upper layers of the Upper Green Marls, 
at Shark River, New Jersey. Collection at Rutgers College. 
VOLUTID. 
Genus VOLUTA Linnezus. 
VOLUTA LELIA, 0. sp. 
Plate xxx, Figs. 1-3. 
Shell of moderate size, attaining a length of 24 inches or more; ovate 
in general outline, with a low spire, moderately ventricose volutions and 
rather slender anterior beak and not strongly marked suture lines; body 
volution forming nearly or quite four-fifths of the entire length, largest 
near the upper end and rapidly contracted below the middle, becoming 
somewhat attenuated in front; aperture large, expanded above and nar- 
rowed below; columella of only moderate size and marked by at least three 
distinct and very oblique folds, enlarging from above downward; canal 
shallow; surface of the shell marked only by fine lines of growth parallel 
to the margin of the outer lip. ; 
This shell is of the same general form as V. Newcombiana, but is smaller 
and with a much lower spire, and is also more attenuated in front, while 
the body volution is not angular in the upper part like that one. It differs 
also from any of the others herein described in the comparative height of 
the spire and attenuation of the anterior end. It is a very neat and grace- 
ful species.
