[Jan. 4, 
Corularia Newberry!, "Win. (Proc. A. N. S., Phil. July, 1865, p. 
130.) From bed No. 4, Sciotoville, Ohio. 
This shell was probably as large as O', byblis. It has the form of a 
quadrangular pyramid compressed in the direction of two opposite angles. 
It differs from C. byblis as follows :—Its form is much more distinctly 
angulated ; the septa range from 17 to 44 to the inch, while in C. byblis 
they range from 56 to 128 to the inch ; it bears a deep Y-shaped furrow 
along each of the angles ; within this furrow the septa are deflected ab¬ 
ruptly toward the base of the shell, so that they meet from opposite 
sides at about a right angle ; the septa also sweep toward the base with a 
gentle curve in their extension across the side of the pyramid, by which 
their centres are about two intervals lower than the portions in the ridge 
which bounds the angle-furrow. In O. byblis the septa-margins also trend 
toward the base, but they are more nearly straight from angle to centre. 
The septa, like those in C. byblis and many other species, are ornamented 
along their margins by delicate granulations. The species appears to 
have been at least three or four inches in length. 
The septa toward the upper end become more direct, and I have little 
doubt that it was the apical portion of this species from which C. New- 
berryi was originally described. 
Ortiioceras Irdiarerse, Hall. (XIII. Rep. N. Y. Reg.) From New¬ 
ark and from bed No. 4, Sciotoville, Ohio. One of the specimens from 
the latterdocality exhibits a broad constriction near the base of the outer 
chamber. From Newark are also fragments of an Ortiioceras having an 
elliptic section and oblique septa. 
Nautilus (Trematodiscus) trisulcatus, M. & W. (Proc. A. N. S., 
Phil., 1860, p. 470. J From bed No. 5, Rockville, Ohio. 
Goriatites Marsh abler sis, Win. 
From Newark, Ohio. Differs from G. Lyoni , M. & W. (AG. j Eyas, 
Hall), in having the transverse section regularly curved instead of broad¬ 
est near the umbilicus ; in having the first and second lateral lobes rounded 
instead of acuminate ; in having an additional accessory lobe and saddle, 
and in having the dorsal'lobe broader and relatively longer. 
Goriatites Shumardiarus, Win. (Am. Jour. Sci. [2] XXXIII, 364, 
May, 1862. J) From Newark, Ohio. 
The specimens of this species, though fragmentary, exhibit nearly all 
the specific characters. 
To the description of G. Shumardianus originally given, may be added 
the following characters, drawn from the Newark specimens : Accessory 
lobe concealed, same form as the lateral one, but only one-tliird its size, 
separated by a parallel-sided, circularly terminated saddle from a nar¬ 
row, elongated, parallel-sided ventral lobe. 
As the three species, G. Allei, Shumardianus and propmquus, are 
closely related in general aspect, their diagnostic characters may be here 
given in stronger contrast. 
G. Allei wants the dorsal lobe—unless we regard the two first-lateral 
together with the dorsal saddle, as a bifid dorsal lobe—and has a closed 
umbilicus.
