LEONTINIA GAUDRYI 



IIQ 



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. 329 ix, and are 

 likewise heavy bones. The following are typical meas- 

 urements: 



Atlas, greatest length 



Atlas, greatest width 



Axis, length of centrum and odontoid process 



Axis, length of odontoid process 



Axis, width across anterior cotyles 



Cervical 3, length of centrum

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 char- 

 acter. 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 fre- 

 quency 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.

The ulna lacks some 60 mm. in the middle of the shaft, 

 but when fitted to the radius its length can readily be ob-
