large as that of the last molar. The premolars are separated by inter- 

 spaces; a character I have not seen in any species of Corypliodon. 



The transverse process of the atlas is rounded distally, and is about as 

 long as wide; the surface for the axis is directed obliquely inward. 



The apex of the scapula is a massive flattened acumination with trun- 

 cate extremity. The spine is elevated and truncate next the glenoid cavity, 

 which is a wide oval, much produced at the coracoid margin. 



In the humerus, the hook of the greater tuberosity is developed, but 

 is not much elevated above the proximal plane. It originates from an 

 external expansion of the greater tuberosity, which bears a shallow con- 

 cavity separated from the head by a low curved subtransverse ridge. As 

 pointed out under Coryphodon latipes, this expansion of the great tuberosity 

 is very large, its width equaling that of the articular surface of the head. 



An almost perfect femur of B. radians is preserved. The third tro- 

 chanter is not very prominent The little trochanter is little developed; 

 the great trochanter is large but does not equal the head. The latter is 

 subglobular, and the ligamentous fossa extends to its rim. The distal 

 rotular surface is prominent, the inner edge more so thaia the outer. Its 

 articular surface is broadly continuous with those of the condyles; a slight 

 emargination of the outlines only marking the usual constriction on each 

 side. In this it resembles Cervidce and some Antilopidce The inner con- 

 dyloid surface is cut ofi" by the emargination in Toxodon and Bos huhalus; 

 the emarginations are deep, but do not cut off either, in Equus, Camelopar- 

 dalis, and three species of Bos ; while they arfe so deep as to cut off both in 

 Bhinoceros, 5 sp.. Hippopotamus, Bos hrachycerus, B. sondaicus, and in 

 Catoblepas. 



The fihida has the inner sharp edge prolonged to the proximal end : the 

 form of the latter is much as in JEobasiletis. The astragalus is slightly con- 

 cave in both directions on the trochlear face, most so anteroposteriorly. 

 The anterior outline of the same is strongly and obliquely convex, and the 

 sui-face is produced sideways into a lateroanterior apex. The inner malle- 

 olar border is thiis very concave; the outer is gently convex with a long 

 fibular facet. The posterior margin is concave, the inner tuberosity pi'omi- 

 nent. The navicular facet is as broad as long, and nearly sessile, being
