112 PALEONTOLOGY OF NEW JERSEY. 
This species, known from internal casts only, differs from all the other 
forms from New Jersey in its greater size; greater angle of the spire; short, 
ventricose volutions, which are strongly rounded with deep sutures; and in 
the proportionally short, compact body v« lution. There are very faint 
indieations of vertical folds on the upper volutions, but too indistinet to fio- 
ure or count. Casts apparently identical with this occur in the Cretaceous 
in Texas, but have not been deseribed. 
Formation and locality: This species is found at Mullica Hill, New 
Jersey, and a very imperfect cast appears to have come from F reehold, New 
Jersey. Both are from the Lower Marls of the Cretaceous. Those from 
Mullica Hill are from the highly ferruginous beds below the true marls.

The only New Jersey example of this species which T have seen is the 
type specimen. Among all the collections examined none have appeared 
that will satisfactorily agree with it. The specimen is a very imperfect 
east, and shows but indifferently the features of the species. It has been 
a rather strong and robust form of about 2 inches in length, with strongly 
rounded volutions, probably four and a half or five in number, and rapidly 
decreasing in size upward; sutures very strongly marked; aperture nar- 
row, but the lip is unknown and the rostrum apparently quite short; volu- 
tious marked by ten or twelve vertical plications or folds which are strongly 
marked on the largest part, but become obsolete at the sutures above and 
below, while on the body whorl they are not visible below the upper two- 
thirds, the lower third being destitute of markings; on outer half of the 
last yolution the folds indistinet or obsolete; the folds appear to have
