He commences by observing, that "the Gayal was mentioned in an early volume of the 'Researches of the Asiatic Society,' (vol. ii, p. 188, 1790,) by its Indian name, which was explained by the phrase "Cattle of the mountains." It had been obscurely noticed (if indeed the same species of Ox be meant) by Knox, in his historical relation of Ceylon (p. 21), and it has been imperfectly described by Captain Turner, in his journey through Bootan, ('Embassy to Tibet,' p. 160).
"Herds of this species of cattle have been long kept by many gentlemen in the eastern districts of Bengal, and also in other parts of this province; but no detailed account of the animal and of its habits has been yet published in India. To remedy this deficiency, Dr. Roxburgh undertook, at my solicitation, to describe the Gayal, from those seen by him in a herd belonging to the Governor-General. Dr. Buchanan has also obligingly communicated his observations on the same cattle; with information obtained from several gentlemen at Tipura, Sylhet, and Chatgaon, relative to the habits of the animal. The original drawing from which the plate has been taken was drawn by a native artist."
Reduced copy of the Plate just referred to.
This representation does not appear to have been taken from a specimen of the animals here described: it bears a much stronger resemblance to our figure of the Gaur, which was taken from the stuffed specimen in the British Museum (see p. 97), than it does to the Gyall (Bos frontalis of Lambert, see p. 51), or to the Gayal, which died in the Zoological Gardens in 1846, from which our figure was taken, which is given on p. 68.
Dr. Roxburgh, who undertook, at the solicitation of Mr. Colebrooke, to describe the Gayal, appears to have done so by the very simple method of copying Mr. Macrae's description of the Gyall, which appeared in the 'Linnean Transactions,' in 1804, to which he has added, that the dewlap is deep and pendant; and this, according to every other account, is not the fact.
With respect to the account given by Dr. Buchanan, I have thought it best to quote it in full; because (although it repeats several of the characteristics already given,) it appears to flow from the pen of one who really observed what he describes.
He says: "The Gayal generally carries its head with the mouth projecting forward, like that of a Buffalo. The head, at the upper part, is very broad and flat, and is contracted suddenly towards the nose, which is naked, like that of the common cow. From the upper angle of the forehead proceed two thick, short, horizontal processes of bone, which are covered with hair; on these are placed the horns, which are smooth, shorter than the head, and lie nearly in the plane of the forehead. They diverge outward, and turn upward with a gentle curve. At the bases they are very thick, and are slightly compressed, the flat side being toward the front and the tail. The edge next the ear is rather the thinnest, so that a transverse section would be somewhat ovate. Toward their tips the horns are rounded, and end in a sharp point. The eyes resemble those of the common Ox; the ears are much longer, broader, and blunter than those of that animal.
"The neck is very slender near the head, at some distance from which a dewlap commences, but this is not so deep, nor so much undulated as in the Zebu or Indian Ox. The dewlap is covered with strong longish hairs, so as to form a kind of mane on the lower part of the neck; but this is not very conspicuous, especially when the animal is young.
"In place of the hump (which is situated between the shoulders of the Zebu) the Gayal has a sharp ridge, which commences on the hinder part of the neck, slopes gradually up till it comes over the shoulder-joint, then runs horizontally almost a third part of the length of the back, where it terminates with a very sudden slope. The height of this ridge makes the neck appear much depressed, and also adds greatly to the clumsiness of the chest, which, although narrow, is very deep. The sternum is covered by a continuation of the dewlap. The rump, or os sacrum, has a more considerable declivity than that of the European Ox, but less than that of the Zebu.
