humerus. The humerus is distinguished by the prominent 

 greater tuberosity, which enters interiorly the prominent and 

 recurved deltoid ridge, extending far down upon the anterior 

 surface, two-thirds the length of the shaft. The characters of 

 this bone are best seen in No. 2780, an animal of the same size. 



The entepicondyle is a rugose tuberosity, the ectepicondyle is 

 more elevated on the shaft, and is marked by an anteverted 

 ridge. The forearm is perfectly preserved upon the right side. 

 The radius covers the front face of the humerus, and the distal 

 faces of the ulna and radius are placed obliquely to the transverse 

 axis of the body, facing upwards and throwing the fore feet and 

 toes outwards rather than forwards. In this specimen the cunei- 

 form does not articulate with the fifth metapodial, as observed in 

 certain other specimens. The manus, as above described, is sub- 

 digitigrade, the lower surfaces of the proximal ends of the meta- 

 podials being slightly raised above the ground. The position of 

 the metapodials in the forward step is, however, much more 

 oblique than in the manus of the Elephant, the lower surfaces 

 being nearer the ground. 



H\\Q pelvis is partly restored in this mount. Its characters are 

 better shown in No. 258. The ilia expand widely, but the antero- 

 inferior border is not extended very far down. The ischia and 

 pubes are strongly developed, and enclose, a wide obturator 

 notch. 



x\ very characteristic feature of the skeleton is the long and 

 rather slender form of the femur and the disproportion between 

 the femur and the tibia, which is much greater than that which 

 exists between the humerus and the radius. The great trochan- 

 ter does not rise to the level of the head. The third trochanter 

 is a long rather low crest, much less strongly marked than in 

 FantolamMa, placed on the upper third of the inner side of the 

 shaft. The lesser trochanter is very prominent, and lies slightly 

 below the middle of the shaft. The patella is a very character- 

 istic bone, but there is some doubt as to its position ; it appears 

 probable that the slender pointed spine of the patella faces up- 

 wards, as the long patella facet is thus made to correspond with 

 the long facet on the inner side of the front face of the trochlea of 

 the femur. 1'he tibia is a very stout bone with a rather low
