CoKULARiA NEWBEEit.Ti, Will. (Proc. A. N. S., Phil. July, 1805, p. 

 130.) From bed No. 4, Sciotoville, Ohio. 



This shell was probably as large as G. hyhlis. It has the form of a 

 quadrangular pyramid compressed in the direction of two opposite angles. 

 It differs from C. hyblis as follows : — Its form is much more distinctly 

 angulated ; the septa range from 17 to 44 to the inch, while in 0. hyhlis 

 they range from 50 to 128 to the inch ; it bears a deep V-shaped furrow 

 along each of the angles ; within this furroAv the septa are deflected ab- 

 ruptly toward the base of the shell, so that they meet froin 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 G. hyhlis the septa-margins also trend 

 toward the base, but they are more nearly straight from angle to centre. 

 The septa, like those in G. hyhlis 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 G. Neio- 

 berryi was originally described. 



Okthoceras Ikdianekse, Hall. (XIII. Rep. N. Y. Reg.) From New- 

 ark and from bed No. 4, Sciotoville, Ohio. One of the specimens from 

 the latter locality exhibits a broad constriction near the base of the outer 

 chamber. From Newark are also fragments of an Ortlwceras 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. 



Goniatites Marshallensis, Win. 



From Newark, Ohio. Differs from G. Lyoni, M. & W. (=(?. Byan, 

 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. 



GoKiATiTES Shumardianus, Will. (Am. Jour. Sci. [2] XXXIII, 0G4, 

 May, 1862. J From Newark, Ohio. 



The specimens of this species, though fragmentary, exhibit nearly all 

 the specific characters. 



To the description of G. SJmmardiccnus originally given, may be added 

 the foUoAving characters, drawn from the Newark specimens : Accessory 

 lobe concealed, same form as the lateral one, but only one-third 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, SJmmardianus and propinqmts, 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.
