162 PALEONTOLOGY OF NEW JERSEY. 
Formation and locality: In the Lower Marl beds in Monmouth County. 
Mr. Gabb’s specimens were from Mullica Hill, New Jersey, and there are 
specimens in the collection Acad. Nat. Sei, Phila., from near Burlington, 
New Jersey. 
CINULIA OVOIDEA.

Acton ovoidea Gabb: Proc. Acad. Nat. Sci., Phila., 1861, p. 319; Meek, Check 
List Cret. and Jur. Foss., p. 17; Geol., N. J., Newark, 1868, p. 728. 
Shell rather large, broadly ovoid or subglobose in general form, with a 
moderately elevated spire, which is rounded rather than pointed; volutions 
about four or perhaps four and a half, with distinctly marked sutures in the 
cast; body volution large, forming almost the entire bulk, and about nine- 
tenths of the entire height of the shell, quite convex in the middle and 
slightly pointed below, with a broad depressed, obscure furrow below the 
top; aperture large, rather more than three-fourths as long as the principal 
volution on the apertural side of the shell, pointed at the upper end, and 
moderately increasing to below the middle of its length; obtusely pointed 
below but wider than above. The columella has been strong, judging from 
the size of the perforation left by its removal, and furnished with a single 
moderately strong tooth near the middle, with an indistinct line below just 
above the margin of the aperture; surface of the shell marked, as obscurely 
indicated on the cast, by a few rather broad spiral lines, the upper one on 
one specimen haying quite a distinct depression below the upper margin, 
except on the outer half of the last volution, and is probably the result of 
accident. 
This species is most nearly related to Solidula bullata — Tornatella? bul- 
lata Morton, in size and general form. It is, however, somewhat more 
erect, has a rather higher spire, coarser surface markings; is somewhat less 
ventricose, has a stronger columella, which is marked by only a single spiral 
ridge of less size than on that species. There is also no indication of the 
extension upward of the last volution near the aperture, as shown on speci- 
mens of that species, nor of any thickening of the outer lip. It is readily 
distinguished from any of the others from New Jersey except A. cretacea
