Typical locality mountains at mouth of Copper Eiver, 

 opposite Kyak Island, Alaska. 



Differs from three preceding races by concavity of fronto- 

 parietal region ; the concavity of inner surface of horn-cores ; 

 and the length, slenderness, and great divergence of the 

 horns, so that while their length is nearly equal to that of the 

 longest known pair of all the preceding races, the tip-to-tip 

 interval is nearly double. 



The range is stated to extend along Pacific coast of 

 Alaska from the Copper Eiver nearly to Cook's Inlet. 



No specimen in collection. 



Subfamily iv.— OVIBOVIN^. 



Although the musk-ox, as was suggested Ijy Gray in 

 1872, may be nearly related to Budorcas, it is considered by 

 Lonn1)erg that it should be referred to a subfamily apart from 

 the Rupicaprinm, and with this opinion Pocock provisionally 

 concurs. 



The subfamily may be provisionally characterised by the 

 caprine type of cheek-dentition, the peculiar form and 

 structure of the horns, which are relatively large in females, 

 the rudimentary tail, the unsymmetrical main hoofs, the 

 retention of lateral hoofs, and the general presence of 

 four teats.
