The three known forms may be thus distinguished :-— 



A. No white caudal disk ; dorsal ridge high. Females dark umber or sepia- 

 brown. 



a. Forehead very concave ; a high ridge, the upper border of which 



is very convex, between the horns. Horns curving much, the 

 points turned inwards. Bos gaurus (the Gaur). 



b. Forehead nearly flat, no elevated ridge between the horns. Horns 

 curving but little, points not turned inwards. Bos frontalis 

 (the Gayal or Mithan). 



B. A white caudal disk. Females reddish-brown approaching chestnut. 

 Dorsal ridge much lower, termination inconspicuous. Forehead narrower 

 and skull longer than in the other species Horns smaller and more 

 curved than in either, the points turned in. Bos Sonduicus (the Banteug). 



Coloured figures of the Gayal have already appeared in the So- 

 ciety's Proceedings' ( $ , 1866, pi. i., $ and young, 1882, pi. x., p. 

 233). Excellent coloured representations of the Banteng are to be 

 found in Sal Miiller and Schlegel's ' Verhandelingen Nat. Gesch. 

 Ned. overz. Bez.' The accompanying figure* (Plate XLIX.) of the 

 young male of Bos gaums, now in the Gardens, is probably the first 

 taken from a living example, though many figures have been given 

 in illustration of Indian sporting and Zoological works.f Not one 

 of these, however, appears to me to be a really good representation 

 of the animal, and I am doubtful whether the portrait of the young 

 tame bull now published will convey a correct idea of an adult Gaur 

 in his native haunts. The photograph of a dead Gaur (apparently a 

 bull just mature), which I now exhibit (see woodcut, p. 594), affords 

 a better conception of the animal than any drawing I have ever 

 seen*. 



A figure of the bull Gayal (Bos frontalis), which serves to shew 

 the proportions, and to some extent the differences of the type, is 

 given in another photograph, kindly lent to me for the purpose 



* This figure is copied from photographs taken in the Gardens by Major J. 

 Fortune Nott, F.Z.S., who has very kindly allowed them to be used for the Plate. 



f The most spirited and artistic is that by \\ elf in Col. Walter Campbell's 'My 

 Indian Journal,' but it is incorrect in several points. Figures of it are given in 

 Forsyth's ' Highlands of Central India,' Sanderson's ' Thirteen years among the 

 Wild Beasts of India/ Storndale's - Seonee,' the same author's ' Natural History of 

 the Mammalia of India and Ceylon,' and Hornaday's ' Two years in the Jungle.'
