The post-glenoid process is large and strong, and the zygomatic process of the squamosal presents a pit for the end of the malar bone jnst in front of the glenoid cavity. The occipital crest shows a median keel on its posterior surface. A cervical centrum, from which tlie epiphyses have nearly separated, shows that these vertebme were proportionally shorter than in number 1255. The vertical diameter is to the longitudinal as 1 to .55, while in number 1255

The post-glenoid process is large and strong, and the zygomatic process of the squamosal presents a pit for the end of the malar bone jnst in front of the glenoid cavity. The occipital crest shows a median keel on its posterior surface. A cervical centrum, from which tlie epiphyses have nearly separated, shows that these vertebme were proportionally shorter than in number 1255. The vertical diameter is to the longitudinal as 1 to .55, while in number 1255 these dimensions are about as 1 to .6. A pyramidal bone, accompanying these specimens, has the face for the fifth metacarpal confluent with that for the unciform, as in figures 117 and 118, page 108, instead of distinct, as on Plate XXXII, figure 6. The specimen (number 1229) upon which the species is based was collected in October, 1873, by Messrs. J. W. Chew and S. Smith, at Tule Springs, Wyoming. This specimen consists of fragments of the skull, limb bones, etc. The geological horizon of this species is in the Bridger beds of the Middle Eocene. The known remains are preserved in Yale College Museum. TINOCERAS," Marsh, 1872. Tiiioceras aiiceps, Marsh.
