82 PALEONTOLOGY OF NEW JERSEY. 
TURBINELLA ? VERTICALIS, DL. Sp. 
Plate 111, Figs. L4, 15. 
Shell turbinate or subglobose, with a moderately elevated spire, which 
has an apical angle of about 90°, and consists of about three and a half 
volutions, which increase rather rapidly in size with the increased growth 
of the shell, especially the last one, which is also very ventricose in the 
upper part, but rapidly contracted below, and produced anteriorly in a 
more or less extended beak; aperture elliptical in form, pointed at the 
upper angle and prolonged below; columella strong, marked opposite the 
middle of the aperture by three slender, almost thread-like, oblique plica- 
tions; surface of the volutions, as shown by the casts, marked by strong, 
rounded, vertical plications or folds, which become obsolete a little below 
the swell of the volution and are also less distinet on the outer half of the 
last one; about eleven of the folds may be counted on the outer whorl. 
I find this species in collections marked. Pyropsis Alabamiensis Gabb; 
but on comparison with the type of that species it proves to be a very dis- 
tinct form, as may be readily seen by comparison with Mr. Gabb’s figure,' 
where it will be seen that that shell has more slender volutions which are 
nearly vertical on the sides or periphery, giving to the specimen a very dif- 
ferent form from the subglobose or subturbinate form of this one. It has 
more the general shape of P. octoliratus and P. septemtiratus of the New 
Jersey beds, but differs very materially in having vertical folds instead of 
revolving ridges, as in both of those species, and from all in the existence 
of the three columellar folds, which entirely removes it from that group 
of shells. 
Formation and locality: Ii the marls of the Lower Greensands at Upper 
Freehold, and in the brown marls of the same position near Burlington, 
New Jersey.
