eastern half of Arizona, together with those of Texas, New Mexico, 

 and the adjacent parts of Mexico, under the name of O vis canadensis 

 tnexicanus. 



The general color of the Kocky Mountain Bighorn is grayish 

 brown, or, as Professor Baird says, " perhaps ashy plumbeous broAvn 

 would express the tint more nearly." A mixture of burnt umber and 

 sepia mixed with more or less white will approximate to most of the 

 dark shades of its coloring. The rump, belly, and posterior surface 

 of the limbs are white. The head, and especially the ears, are paler, 

 and the muzzle is whitish. The tail is colored like the back, and con- 

 nected with it by a narrow line of 

 the same color. The horns are yel- 

 lowish brown. The feet, which are 

 elastic cushions, are plumbeous 

 black. The horn figured herewith 

 (fig. 34} is that of an adult male, 

 killed on a little hill beside the 

 ranch house, at Dog Spring, (ilrant 

 County, New Mexico, September 

 11, 1893, and agrees in size and 

 shajje with others from the 

 Dog Mountains, in the same region, 

 collected by our party in 1892. 

 Two of the horns (Nos. 631G1 and 

 36332, U.S.N.M.) measured, re- 

 spectively, 390 and 360 mm. in cir- 

 cumference at base, and 900 and 800 

 in length, following the outer curve. Horns from the Verde Valley, 

 in central Arizona, are also quite "similar, as are those from San Fran- 

 cisco Mountain."
