NOTES ON THE CRETACEOUS FOSSILS OF COALVILLE, UTAH, 



1. Ostrea soleniscus Meek. 



This remarkable oyster ranges through something more than the upper 

 half of the fossiliferous series that is exposed in the vicinity of Coalville. 

 So far as I am aware it has been found only in the region bordering the 

 eastern hank of the Wasatch Mountains. 



2. Ostrea coalvillensis Meek. 



This species is very much like the forms of 0. glabra which are found 

 at Point of Eocks Station and elsewhere in the Laramie Group, to which 

 Mr. Meek gave the name of 0. wyomingensis. It is assumed to be of a 

 different species because of its known difference of geological position, 

 but comparatively little is known concerning it, as only a few examples 

 have been found. 



3. Ostrea congesta Conrad? 



Numerous examples of a small oyster were found attached to the large
