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, 
extending on one-third the length of the shaft. The shaft is moderately 
compressed at the middle, but transversely flattened below. It is nearly 
straight. The condyles are narrow, and the inner and outer tuberosities 
almost wanting ; their position marked by shallow concavities. The ex- 
ternal continues in a lateral crest which turns into the shaft below the 
lower third. The inner condyle is both the widest and most prominent ; 
the external has its carina at its middle, and its external trochlear face 
oblique and narrow; narrowest behind. The olecranar and coronoid 
fosse are deep and produce a small supra-condylar foramen. 
The ulna exhibits a large and obtuse olecranon, concave on the external 
face. Its glenoid cavity is narrowed and elevated behind; in front it 
widens, and there the ulna receives the transverse proximal end of the 
radius, which overhangs it on both sides, leaving the little elevations of 
the right and left coronoid processes about equal. The vertical diameters 
of the shaft of the ulna are about equal throughout, Its section is tri- 
angular, the base being next the radius for the proximal third. This is 
followed by an edge next the ulna, and the base of the section is on the 
outer inferior aspect, an account of the direction of an angle from a short
