THE COPPER RIVER WHITE GOAT 



[Orcamnus montaniis kenuedyi) 



The skull and scalp of a white goat obtained in the autumn of 1899 

 by Mr. V. S. Kennedy, of Chicago, from the mountains at the mouth of 

 Copper River, opposite Kyak Island, have been regarded by Dr. D. G. 

 Elliot ^ as sufficiently distinct from the ordinary form to entitle them to be 

 described as a species apart. In addition to certain details in the con- 

 formation ot the skull which need not be repeated here, this specimen is 

 distinguished by the form and curvature of the horns. These are much 

 more slender than in the ordinary white goat, and instead of curving 

 regularly backwards till near their tips, bend widely outwards from their 

 bases. Their length is nearly equal to that of the longest pair of the 

 ordinary form hitherto recorded, while the tip -to -tip interval is nearly 

 double that of any other known specimen. 



Whether these peculiarities are constant or merely individual must be 

 decided by the acquisition of other specimens from the same region. In 

 any case the variation can scarcely be regarded as indicating a difference of 

 higher than racial value.

( Antilocapra amej'icanci) 



(Plate VII. Fig. 4) 



In America this ruminant is almost universally called an antelope ; 

 but, although it is of course possible to make any term as elastic as may be 

 desired, the use of that name for such an aberrant creature is much to be
