MAMMALS— (JEEVID^E— CAEIACUS VIRGINIAN US VAR. 73 



The horns, still in the velvet, but beginning to polish, and probably 

 about full grown, are like those of C. virginianus, in showing a strongly 

 curved main beam, with the tines springing from its upper border, instead 

 of the doubly dichotomous construction witnessed in G. macrotis and colum- 

 bianus. The first tine, 2£ inches long-, springs about the same distance 

 above the burr ; the next, and main tine, 6 inches long, springs midway 

 between the first and the forking 1 of the beam. This forking results from 

 the approximately equal size of the main beam and distal tine (4 or 5 

 inches); but its lower prong is clearly seen to be the main shaft of the horn, 

 thus carrying out completely the pattern characteristic of C. virginianus. 

 The ends of the horns are only 4 J inches apart, and about lh inches dis- 

 tant each from the burr of its own side. The ends of the main tines are 

 10 inches apart; the width of the horns across at the broadest point is only 

 about 13 inches. 



The tail is like that of G virginianus in form and color, but much 

 smaller. It is broad, flat, lanceolate, and somewhat distichous. The verte- 

 bras are only about 5 inches long (as well as can be judged from the state 

 of the specimen), beyond which the hairs project 3 inches. The ears are 

 shaped as in G. virginianus, but are smaller and only very scantily pilous 

 outside, where the skin is in plain view ; inside, they are better clothed with 

 long flocculent hairs on the concavity itself, and a closer pilous coat on the 

 edge and flat terminal part. 



The distance from the end of the metacarpal bone to the tips ot the 

 hoof is a short 11 inches. The sole of the fore hoof is 2 inches long by 

 If broad. The distance from the heel to the end of the hind hoofs is 151 

 inches, of which the calcaneal portion is about 3 inches, and the digital 

 portion 4. The hind hoofs are shorter and especially narrower than the 

 fore. Both hoofs are black, as are also the false hoofs. As well as can be 

 determined in the dried state, the metatarsal glands are small and like those 

 of C. virginianus. 



The prevailing coloration of this animal, taken in September, which is 

 still " summer" in Arizona, is a pale, dull fawn color, with a peculiar ochreous 

 shade, brightening into clearer tawny or reddish-brown all around where 

 the color of the upper parts joins the white, of the under portions, and on
