The type specimen of this species (number 1038) was obtained by IVressrs. B. D Smith, J. W. Chew and the author, two miles east of Big- Hone Buttes, Wyoming-, September, 1872, and September, 1873. This specimen consists of a skull, and numerous parts of the skeleton. The geological horizon of this species is in the Bridger Beds of the Middle Eocene. The remains of this specimen are preserved in Yale College Museum. Dinoceras reflexiim, Marsh, n. s. Woodcut : 174, below. Figure 174.—Nasals at Dioceras reflexum, Marsh (No. 1229). a. side view; b. top view ; c. front view. One-fifth natural size. In the type of this species (number 1229), the nasal protuberances are small, but prominent, and are directed strongly upward. The nasal bones are completely united to the end, but are there terminated by sutural surfaces, looking nearly downward, and indicating the position of the prenasal bones, Avliich have fallen away.
