136 On Dr. Grard’s collection of Spiti fossils. [No. 2, 
cula. Allowing for the distortion of the specimens, the form so 
closely resembles that of WV. cwneiformis from the Cutch Oolites that 
I cannot hesitate to regard them as specifically identical.

The specimens of this shell are much crushed, so that their form 
is not accurately determinable, but it appears to be identical with 
the Cutch species, and is characterised by similar sharp radiating 
ribs, with lines of growth strongly marked towards the margins. 
23. InocERAMUS? 
A large concentrically-undulated shell, in bad preservation, ap- 
pears to belong to this genus. Also a smaller fragment, marked 
with deep broad concentric furrows distinct from the above. The 
specimens are insufficient to admit of specific description.

margine cardinali recta ; concentricé striata, superné angusté incisa.

In form, and in the sculpturing of the left valve, much resembling 
Inoceramus concentricus of the Gault. The right valve resembling 
that of an Anomia in form, with a deep linear notch just under the 
hinge line. The specimens are not very perfect. They are embed- 
ded in a black siliceous stone, similar to that of the nodules in which 
the Ammonites are enclosed, They are associated with Belemnites 
Sulcatus.
