Peterson: Material Discovered in Uinta Basin. 



85 



O. C. Marsh saw the close rehilionship between these Uinta and Oligo- 

 cene genera and even referred one specimen to Agriocharus {A. 

 puniiliis)^'^ 



The present restoration is effected from the remains of the type 

 specimen No. 2962, with the exception of the posterior portion of the 

 tail, which is reproduced from the paratype No. 3020. The portions 

 on Plate XLI indicated in outlines are obtained from other individuals 

 and are thought to be approximately correct. 



In this, connection mention should be made of the fact that the 

 vertebral column was found dislocated at the first dorsal (see fig. 13),

 column in the original position as found in the field. 



and that one or possibly two vertebrae in this region are wanting. 

 The posterior dorsals and all the lumbars, the sacrum, and the pelvis 

 were found in position. The skull and atlas were in nearly their 

 proper position with reference to the location of the neck, while the 

 limbs and feet were more or less dislocated. 



From this it is plain that we cannot be positive in regard to the 

 number of the vertebrae in the dorsal region. Thirteen dorsals, the 

 same number as in Merycoidodon, are given in the illustration, which 

 may or may not be correct. On the other hand there is no doubt in 

 regard to the lumbar and the sacral series which are six and three
