GASTEROPODA OP THE EOCENE MAELS. 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 Grreen Marls, 

 at Shark River, New Jersey. Collection at Rutgers College. 



VOLUTID^. 



Genus VOLUTA Linnaeus. 



VOLUTA LELIA, n. Sp. 



Plate XXX, Figs. 1-3. 



Shell of moderate size, attaining a length of 2 J 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 entu'e 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 diff"ers 

 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. 



Formation and locality: In the upper layers of the Upper Green Marls, 

 at Shark River, New Jersey. From the collection at Rutgers College.
