Cojje (Uintatherium aneeps.)—Proceedings of the American Philosophical Society, Vol. XIII, p. 61, 1873. The type specimen of this species was of small size, and evidently a female. The occiput is elevated, and has a median vertical I'idge. The lateral crests extend from the front nearly to the summit of the parietal protuberances. The latter are connected by a strong ridge passing directly over the brain-cavity. The post-glenoid processes are triangular in horizontal section, with the apex outward, A second specimen (number 1266) has the nasal protuberances of moderate size, and resembling those of Tinoeeras grande. The prenasal bones are firmly co-ossified with the nasals. The type specimen (number 1030) was discovered by Lieut. W. N. Wann, in September, 1870, on the Divide near Sage Creek, fifteen miles southeast of Fort Bridger, Wj^oming. The remains of this specimen consist of portions of the skull, cervical and dorsal vertebrae, and a tibia. The second specimen (number 1266) was found by Messrs. J. W. Chew and L. Lamotte, in August, 1874, in Wyoming. It consists of portions of a skull, and a few other bones. The geological horizon of this species is in the Dinoceras beds of the Middle Eocene. The known remains of this species are preserved in the Yale College Museum.
