. Dinocerata : a monograph of an extinct order of gigantic mammals. Dinocerata; Mammals, Fossil; Paleontology; Paleontology. 214 DINOC'ERATA. The teeth preserved are but h'ttle worn, indicating a fully adnlt, but not old, animal. Another specimen (nnmber 1533) referred to this species is quite unlike any other in the collection in the form of the nasal bones so far as preserved, but, unfortunately, the specimen is considerably eroded. The snout, instead of tapering, expands forwaixl, and presents on each side a broadly rounded, horizontal protuberance, scarcely rising at all above the general level of the nasal bones. They, also, project forward, far beyond the end of those bones, Avhich were thoroughly consolidated, and directed somewhat downward, underneath the broad shelving- jn'otuberances. The left maxillary protuberance preserved with this specimen is of large size, and flattened on its outer side. This species, with Tiuoceras cornutum, forms a distinct sub-genus of Tinoceras, A^'hich may be called Plafoceras. The type of this species (number 1242) was obtained in September, 1873, by Mr. L. Lamotte and the author, near Spanish John's Meadow, Wyoming. The remains of this specimen consist of portions of the skull, and teeth. A second specimen (number 1533), apparently a very old individual of the same species, was found in Ma}^, 1875, by Messrs. S. Smith and S. Pearson, at Haystack Mountain, Wyoming. This specimen consists of portions of the skull. The extremity of the nasal bones is figured above. The geological horizon of these specimens is in the Bridger beds. The known remains of this species are preserved in Yale College Museum. Tinoceras longiceps, Marsh. Woodcuts: 38, p. 37; 48, p. 43; and 191, 192, below. Fig. 19-'..
