ond lateral lobe wanting. Dorsal saddle parabolic; lateral sad- 
dle siak 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 (82); dorso-ventral dimention -49 (48); 
distance from tip to tip of two dorsal lobes nearest the aperture 
‘23 (28); 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 G. Allei, but is laterally 
more compressed, with a sharper dorsum, and unlike that, has 
but one lateral lobe. 
GoNIATITES PROPINQUTS, N. sp. 
_ 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. rsal 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. : aoe
