G. Shumardianus has a simple dorsal lobe and an open umbilicus. 
G. propinquus has a shorter and narrower dorsal lobe than G. Shumar- 
dianus , with a closed umbilicus.

Goniatites Ohiensis, n. sp. 
Compressed-globoid, deeply and broadly umbilicate. Dorsum rounded, 
sides considerably and somewhat obliquely flattened, so as to give the 
widest transverse section near the borders of the umbilicus, this diameter 
being to the dorso-ventral as 4 to 3. Dorsal lobe oblong, parallel-sided, 
obtuse, separated, by a broader and longer, obtusely rounded dorsal sad¬ 
dle, from a subclavate, acute lateral lobe, which reaches half its length be¬ 
hind the dorsal one. This lobe is followed by a very broad shallow saddle 
having its apex turned obliquely toward the dorsum. Second lateral lobe 
small, equilaterally triangular, situated on the brink of the umbilicus. 
Greatest transverse diameter, fifteen-sixteenths of an inch ; dorso-ven¬ 
tral diameter, twelve-sixteenths; diameter of umbilicus, seven-sixteenths. 
Differs from G. Shumardianus in it's parallel-sided, obtuse dorsal, and 
linguiform, acuminate lirst lateral lobe ; also, in the oblique position of 
the lateral saddle. There is no species likely to be confounded with it 
unless it be G. Andrew si , which has the sides more convex, and differs 
also in its acuminate-clavate dorsal lobe. 
From Newark, Ohio. Collected by Rev. II. Herzer. 
Goniatites Andrewsi, n. sp. 
Compressed-globoid; deeply, broadly and abruptly umbilicate. Rounded 
on the sides, and more rapidly on the dorsum; greatest width close to the 
umbilicus; transverse diameter to the dorso-ventral as 4 to 3. Dorsal 
lobe long, clavate, acuminate, separated by a sub-clavate broadly rounded 
saddle from the first lateral lobe, which is also clavate-acuminate, but a 
little broader than the dorsal, and a trifle shorter. This is followed by a 
very broad, obliquely situated saddle, having its dorsal side concave in 
the middle, and its umbilical side gently convex. The whorls are marked 
each by about four constrictions. In one specimen, which seems to pre¬ 
serve a portion of the shell, it is seen to present somewhat uniform, close¬ 
ly-set, transverse wrinkles in the region near the umbilicus. Casts of the 
umbilicus retain the impression of every whorl to the very apex, and show 
that this species attained seven or eight volutions, the later of which in¬ 
creased in transverse diameter more rapidly than the earlier. 
From Newark, Ohio. Collected by Rev. H. Herzer. 
Cythere crassimarginata, Win. (Proc. A. N. S., Phil., Sep.. 1802.). 
From bed No. 5, Rockville, Ohio. Some of the specimens attain twice 
the dimensions of the types of the species. 
• Piiillipsia Missotjriensis, Shum. sp. 
From Newark, Ohio. Collected by Rev. H. Herzer. 
All the known characters of the species are exhibited, except the gran¬ 
ulations of the surface, which the state of preservation of the specimens 
renders it impossible to detect.
