Habitat. — In open country throughout India except 

 in Lower Bengal and Malabar. 



This animal is too well known to need much descrip- 

 tion. The colour of the old males is a deep blackish 

 brown — almost jet black in some — whence the popular 

 " Black-buck." The back of the head, nape and neck 

 are hoary yellowish and the underparts and inside of 

 limbs pure white. The females are yellowish brown 

 with a pale streak from the shoulder to the haunch, 

 pure white below — they are hornless but I have on 

 several occasions come across females with slender 

 smooth horns. I figured one head for the Bombay 

 Natural History Society — the horns were 12 inches 

 long — thin and smooth and curved downwards. 



The heads in this collection are above the average. 



No. 40. — Portax pictus. —The Nylgao— or Blue

Habitat. — India generally from the Himalayas to

 sula.
