The ribs are long and slender, the first but little expanded distally and 

 united with the manubrium sterni a little behind its middle. They num- 

 ber eighteen, but as the last is quite long, there may have been another 

 pair of shorter ones not yet exposed in the matrix.

There are four sternal segments preserved, with a fragment of another. 

 They are distinct, and the first is the largest. It is a longitudinal plate, 

 placed on edge, with the anterior border strongly excavated. The in- 

 ferior margins of the succeeding segments are thickened, but the com- 

 pressed form remains, the section being triangular. 



The scapula is large for the size of the animal. It has an approxi- 

 mately triangular form, the base being superior. The posterior angle is 

 right, but the anterior regularly rounded. The apex supports the glenoid 

 cavity on a neck which is contracted by a shallow excavation of the 

 anterior margin. The latter is bounded next the glenoid cavity by the 

 short obtuse coracoid, which stands a short distance above the articula- 

 tion. The spine is long, rather elevated, with a regular convex border 

 curved backwards.

Humerus. The head is directed a little inside of directly backwards. 

 The bicipital groove is very deep and the inner tuberosity large and 

 directed forwards. The external tuberosity is much larger, as usual in 

 this group of ungulates, and rises in a hook-like apex above the level of 

 the head. The external bicipital ridge is -lateral, and not very prominent,
