CREODONTA. 319 



The specimen above noted as No. 2 presents a good many parts of the 

 skeleton, from which I derive the following characters:

Length of centrum of a lumbar vertebra 025 



Length of centrum of a caudal vertebra 027 



Length of centrum of a caudal vertebra 030 



The dorsals measui'ed are depressed artificially, but their length, is not 

 apparently altered. The caudals are nearly perfect. Their neural arch is 

 complete, but is relatively shorter on the shorter centrum than on the longer 

 one; on the latter it has no spine. There are two transverse processes on 

 each side separated by a notch. On the shorter vertebra they are nearer 

 together, and the posterior is the larger. The inferior surface is regularly 

 convex medially; at the extremities it presents two tuberosities, of which 

 the anterior are the most prominent. 



The radio-carpal articular facet is short transversely. Surrounding it are 



four tuberosities. One of these forms the internal angle of the bone; the 



others are near the external end, one superior and one inferior; the fourth 



is at the superior side of the ulnar facet.

The head of the tibia is characterized by the failure of the internal 

 femoral facet to reach the posterior border. It thus leaves a free ledge. 



The anterior face of the distal extremity of the tibia is slightly con- 

 cave. The malleolar process is large and truncate, and is not grooved, but 

 rises into a low, wide tuberosity at the base. The fibular face is oblique to
