In the extreme northern end of the Egan Range Mr. Emmons* col-lected probable Carboniferous fossils. On the western front, about12 miles north of Cherry Creek, the following fossils were collected bythe writer and identified by Dr. Girty: Orbiculoidea missouriensis ?Marginifera splendens ?Prodiictus 11. catilloldes. Between Egan Canyon and Ely it is probable that the Carboniferousrocks cover a considerable area. Near Ely, Carboniferous limestonesare abundantly exposed. About 2 miles south of Summit Springs,on the road between Ely and Hamilton, massive semicrj^stalline lime-stones are found which carry a probablj^ Upper Carboniferous fossilthat was determined by Dr. Girty as Zaplirentis sp.
