510 EXTINCT AND VANISHING MAMMALS 



Family BOVIDAE: Cattle, Sheep, Goats, and Antelopes 



About 60 genera are recognized in this family. Lydekker (1913c) 

 and Lydekker and Elaine (1914) list approximately 485 species 

 and subspecies in their catalogues. The family is nearly worldwide 

 in distribution, but the West Indies, South America, Madagascar, 

 and the Papuan and Australian regions are lacking in indigenous 

 species. In the preceding volume Dr. Allen (1942) discusses 17 New 

 World forms. In the present volume there are full accounts of about 

 102 forms, with remarks on a number of additional forms. Thus 

 the total number of extinct or vanishing forms is considerably 

 greater in the Bovidae than in any other family of mammals. Man 

 has required the grazing grounds of many species for his domestic 

 flocks or his cultivated fields, and he has destroyed other species 

 for their flesh and hides. Since man has raised himself from sav- 

 agery to civilization primarily with the help of domesticated ani- 

 mals, his debt to certain members of the present family (cattle, 

 sheep, and goats) is immense.

The very recent discovery of this wild ox in Cambodia is com- 

 parable to that of the Okapi in the Belgian Congo a generation 

 previously. Its present population is estimated "at about a thou- 

 sand head." (Coolidge, 1940, pp. 424, 521.) 



The Kou Prey differs from both the Gaur and the Banteng. It 

 attains a shoulder height of 1.9 m. (6 feet 3 inches). The old bulls 

 are black, with whitish patches on shoulders and rump; the cows 

 and calves are gray; lower part of the limbs white; dewlap pro- 

 nounced; tail long; slender legs longer than in the Banteng; feet also 

 very slender. The horns are cylindrical, widely separated, recurved 

 in front in the bull and lyre-shaped in the cow; in some old males 

 they are curiously frayed near their tips. (Urbain, 1937a.) Greatest 

 spread of horns, 840 mm.; tip to tip, 460; length on outside curve, 

 810 (Coolidge, 1940, p. 442). 



i This name is perhaps antedated by one or more of the numerous names 

 proposed by Heude (Mem. Hist. Nat. Empire Chinois, vol. 5, pt. 1, pp. 2-11, 

 pis. 3-11, 1901) for the wild cattle of Indo-China.
