CONDYLAETHRA. ' 431 



well developed as in tapiroids. The condyle has no intertrochlear ridge, but 

 the cylindrical part is swollen, as in Oreodon, Anoplotheriwn, and Mesonyx. 

 The epitrochlear foramen is a peculiar feature already mentioned. The head 

 of the i-adius is transversely oval, without inferior interlocking angle. The 

 distal extremity is truncate, and the scaphoid and lunar facets are not dis- 

 tinctly separated. The distal extremity of the ulna is a compressed tuber- 

 osity which is produced beyond the radius, ta which it is oblique. 



The scaphoid is rather larger than the lunar, and has a considerable pos- 

 terior tuberosity. Its radial facet is transverse and anterior, and the median 

 part of the bone is concave. The inferior face is one large facet for the trape- 

 zoides. The facet for the trapezium is small and lateral. The facet for the 

 magnum is small and is entirely lateral. The radial face of the lunar is 

 larger, and the rest of the superior side of the bone slopes downwards and 

 is less concave. The inferior face is occupied in front almost exclusively 

 by the facet for the magnum. A narrow facet for the unciform forms a 

 narrow band along the external part of the inferior face. The cuneiform 

 has considerable transverse extent. Much of its superior face is occupied 

 by a concave facet for the ulna; the external part is contracted, and termi- 

 nates acutely. The inferior face is nearly flat. The trapezoides is a shallow 

 disciform bone, entirely supporting the scaphoid, and not joining the lunar. 

 The magnum has a resemblance to that of Goryphodon. It has an anterior 

 face, a posterior tuberosity, .and an elevated smaller superior tuberosity. 

 It is narrow, and the inferior facet is simple and concave. The unciform is 

 a good deal like that of Tapirus, but has a small posterior tuberosity. 

 Viewed from before it is subtriangular, the cuneiform face being the hypoth- 

 enuse. There is no distinct facet for the lunar articulation, as is seen in 

 CoryphodoH and Bhinocerus. It has two inferior facets. The trapezium is 

 lost from the specimens of both species. 



The distal keels of the metapodial bones are distinct, but are quite short, 

 and entirely posterior. 



The pelvis is of normal proportions. The ilium is not much expanded, 

 but its posterior superior border is thinned out. The anterior border is de- 

 curved in front. The peduncle is distinct and rather short, and has a trian- 

 gular section, the narrower face being anterior and only apparent near the
