The Seminole sandstone and conglomerate beds that run north- 

 ward through the Territory are, as a rule, barren of fossils, and no 

 collections of importance were made in them. 



Pawnee and Pawhuska Beds. — Collections of fossils from these 

 beds were made at ten different localities. These fossils were col- 

 lected from strata that apparently extend from the base of the Paw- 

 huska limestone to a horizon three hundred or four hundred feet 

 above that limestone. The first five lists of fossils come from strata 

 that appear to belong to the Pawhuska limestone. One to four 

 miles southwest of Arlington the following fossils were found in a 

 limestone bed.
