16 [365] A. Winchell on supposed New Cephalopods. 
ond lateral lobe wanting. Dorsal saddle parabolic; lateral sad¬ 
dle very broad, and extending one and one-fourth times as far 
forward as the dorsal, and having its umbilical branch much 
more abrupt than the lateral one. 
Greatest diameter of shell seen 1*02 (100); greatest transverse 
diameter of section *33 (32); dorso-ventral dimention *49 (48); 
distance from tip to tip of two dorsal lobes nearest the aperture 
*23 (23); greatest width of umbilicus *23 (23). 
Locality. From the gritstones in the vicinity of the quarries 
near Pt. aux Barques. 
This species is closely related to Or. Allei, but is laterally 
more compressed, with a sharper dorsum, and unlike that, has 
but one lateral lobe. 
Goniatites propinqtjus, n. sp. -kx w ■ .yc 
Shell of moderate size, closely involute, with a closed, slightly 
indented umbilicus; slightly compressed, with a well rounded 
dorsum, and moderately convex sides making with each other 
an angle of about 10°. Septa rather remote. Dorsal lobe of me¬ 
dium size, infundibuliform, obtuse; lateral lobe extending half 
its length behind the dorsal, infundibuliform, slightly rounded 
at the apex, and with a base equal to the height; second lateral 
lobe wanting. Dorsal saddle parabolic; lateral saddle somewhat 
semicircular, but most convex anteriorly. 
In the only specimen seen, the dorso-ventral dimension is *65; 
the greatest diameter of transverse section (close to umbilicus) 
is -43. 
Locality. From the gritstones in the vicinity of Pt. aux 
Barques with G. Shumardianus and G. Oweni. 
Closely related to G. Shumar dianus, but has a more broadly 
rounded dorsum, with sides more nearly parallel and wants the 
open umbilicus. The lateral lobe is also much more produced 
posteriorly and both lobes are probably a little less acute. 
A Goniatite having the general form and appearance of the 
three preceding species has been found at Marshall, in fragments 
which are marked by occasional sinuous transvere furrows, and 
while its single lateral lobe separates it from G. Allei, its more 
rounded dorsum differs from G. Shumardianus. Should it prove 
distinct it may appropriately be called G. sulciferus. 
Goniatites sinuosus ? 
Hall (Geol. Rep. 4th Dist. N. Y., p. 245). 
I have in my possession several specimens of an involutely 
coiled shell which cannot be distinguished by the aid of Prof. 
Hall’s figure and brief description from G. sinuosus. At the 
same time some doubt exists in reference to the Goniatitic char¬ 
acter of my specimens. The septa are very imperfectly shown, 
but by comparing different individuals, it appears that they form
