The atlas associated with skull No. 3335 is a decidedly heavy bone in all its proportions. The axis and the third cervical were associated with skull No. 3291x, and are likewise heavy bones. The following are typical measurements:

Atlas,greatest length86 mm.
Atlas,greatest width170 mm.
Axis,length of centrum and odontoid process 132 mm.
Axis,length of odontoid process34 mm.
Axis,width across anterior cotyles98 mm.
Cervical 3,length of centrum66 mm.
Cervical 3,width of posterior end of centrum55 mm.

While there are other vertebrae in the collection, which probably belong to this species, I have not cared to make the association without some evidence of a definite character. However, in the case of a fore limb, which was found fairly near one of the skulls, is of proper size, and because this humerus occurs with something like the frequency of the skulls, I have been convinced that it belonged to this species, and so described it under the genus. This specimen consists of the two humeri, the radius and the ulna, No. 3328.
