of the tail is broadly black at the end, grizzled with gray, and rusty 

 toward the base. The ears are extremely large and thick, densely 

 coated with hairs on both surfaces, those of the concavity being long 

 and somewhat curly. In proportion to the size of the animal the 

 ears are nearly or quite as large as those of the mule deer. The 

 tail is short, full, and foxy, the white hairs not covering more than 

 the lower half of its surface. The metatarsal glands are smaller 

 than those of the mule deer, larger than in white-tailed deer. They 



are surrounded by a small 

 tuft of whitish hairs which 

 barely suffice to mark their 

 location. There are no 

 dusky hairs surrounding 

 the light ones. The tarsal 

 glands are also small, with 

 inconspicuous tufts. There 

 is nothing distinctive about 

 the form or size of the 

 hoofs or antlers ; their 

 measurements are given
