BOVINE 63 



which the colour of the hair is known may be conveniently 

 introduced here : — 



A. Both sexes dark; horns regularly curved in a, 



suboircular manner. 

 Size medium B. c. simpsoni. 



B. Adult bulls dark, young bulls and cows red or 



tawny ; horns more expanded laterally. 

 u,. Throat of bulls orange tawny. 



a'. Size large; throat of cows orange.... B. c. planiceros. 

 V . Size smaller ; throat of cows coloured 

 like neck ; horns mainly in one 

 plane ; ear-fringe of cows partly 



orange (some old bulls red) B. c. hunti. 



h. Apparently no orange on throat. 



Size medium; horns strongly bent 

 backwards ; ear-fringe of cows 

 mainly black B.C. hrachyceros. 



c. Adults of both sexes rufous or tawny ; horns 

 more or less ungulated and flattened. 

 a. Size small ; horns strongly ungulated ; 

 heavy ear-fringes ; apparently a dark 



dorsal stripe B. u. namis. 



i. Size apparently larger ; horns less strongly 

 ungulated; less abundant ear- fringes ; 

 no dark dorsal stripe B. c. heddingtoni. 



In the present race the horns, so far as can be determined, 

 are of the general type of those of planiceros, but with the 

 tips inclined more backwards and inwards, so that the 

 interval between them is less. Old bulls apparently black, 

 younger ones, like cows at all ages, rufous or tawny, with 

 black " points." Apparently no orange on throat.
