with a female leopard, F’. leopardus. Also the female Mexican 
jaguar, F. hernandezi, has bred with the male of the common 
jaguar, F’. onca, in the gardens of the Zoological Society. 
(P.Z.S. 1861, p. 141). 
In the Proceedings of the Zoological Society for 1849 a 
hybrid was recorded as having been imported from India, and 
which appeared to be the produce of a zebu, Bos tawrus var. 
Indicus, mother, and a yak, B. grunniens, sire (p. 172). Mr 
Bartlett, before the same society in 1884, recorded some 
remarkable hybrids which he had reared in the gardens, a 
history of which will be found recorded by Mr Tegetmier in the 
Field. The zebu, or common Indian cattle, was the female 
employed for the first cross, and the gayal, Bos frontalis, the 
male: this latter being found wild to the east of the Brahma- 
putra, at the upper end of Assam, from whence it extends north 
and east to the borders of China, and downwards through 
portions of Burma. It breeds freely in captivity, and is of a 
gentle disposition. 
“ Several hybrids have been bred in the Gardens between 
this species and the male zebu. The first of these was born on 
October 29th, 1868. In due course she was mated with a zebu 
bull, and produced five three-quarter bred calves on the follow- 
ing dates :—The first on June 16th, 1872; the following on 
October 16th, 1873: January 5th, 1875; March 11th, 1876; 
and the fifth on November 2nd, 1878. She was then mated to 
an American bison, and on May 21st, 1881, gave birth to a 
female calf, which combined in itself the blood of the zebu, 
gayal, and American bison. This remarkable animal might 
almost pass muster for an ill-bred cow. Its head and horns are 
not unlike those of the gayal, and its withers are very high, the 
udder being small. In colour it is a dull brownish black, paler 
on the ears and around the eyes, and with a light muzzle. 
When two years old she was mated to a bison bull, and on 
March 12th, 1884, produced a female calf, which, according to 
one mode of stating the pedigree, is one-eighth gayal, one- 
eighth zebu, and six-eighths bison, and, as might be expected, 
showed very little trace of its cross-bred origin. It was, when
