External Characters. Color above bluisli-black, lighter 

 on the sides and ventrally, thickly varied with small irregular 

 spots of whitish ; head and limbs nearly uniform black. Some- 

 times the light grayish- white tint prevails, varied with spots of 

 dark-brown or blackish. Length of full-grown male about 7^ 

 to 8 feet ; of full-grown female about 7 feet. The young are 

 born white, with a soft woolly pelage, but this is soon changed 

 for the harsh, stiff covering of the adults, and the color changes 

 to a uniform brownish, or more or less silvery-gray, lighter on 

 the sides, and whitish below. 



DeKay describes the male as ha^^ug the " Head small in pro- 

 portion to the body, with a moveable muscular bag on its sum- 

 mit, extending from the muzzle to about live inches behind the 

 eyes, and in certain positions nearly covering the internal canthi. 

 This sac is twelve inches long, and, when fully distended, nine 

 inches high, covered with short hairs, and with sHght trans- 

 verse wrinkles. The nostrils are round, each two inches in di- 

 ameter, and pierced in the anterior part of this hood. When 

 the hood or nasal sac is not inflated, the septum nasi can be 

 distinctly felt, elevated into a ridge about six inches high. . . . 

 Xasal sac bright brown or rufous." *
