Dr. Buchanan's figure, in the India House Library, was the first, and is the best yet given of this species. 
The Jungly Gau, figured by M. F. Cuvier, is from a tracing made by M. Duvaucel from a drawing of 
General Hardwicke, taken from a specimen bred between a domestic Gayal and a Zebu ; it has a larger, 
deeper, and more waved dewlap than the wild specimen, and differently shaped horns. 
There was a specimen of this species, recently alive, in the Zoological Gardens, which was sold in Cal- 
cutta, when young, for the calf of a common Bull. 
** Forehead concave ; horns pale, rather depressed at the base. Back with a prominence over shoulder and over middle 
of back.
