NATIVE NAMES.—Kok, Canarese; Golatta-koku, Telegu of the Yanadees; Yea-kwet (?) Burmese.
HABITAT.—Southern India and Ceylon, probably Burmah, as one species is mentioned there by Blyth.
DESCRIPTION.—Head short and truncated, with a deep muzzle; ears nearly round, semi-nude, sparsely covered with minute hairs; eyes moderately large, half-way between snout and ear; feet largish; claws short and stout; tail nearly equalling length of head and body, semi-nude, ringed, and with short brown bristly hairs round the margin of the annuli; whiskers full and long; colour of the fur—which is harsh and long, as in the rest of the genus, and of the usual three kinds—is a brown, mixed with a tinge of fawn; the under-parts are whitish, with a yellowish tinge; the nose, ears, and feet are dark flesh-coloured or brownish, and the feet are covered with short brown hair. The incisors are orange yellow; the claws yellowish.
Sir Walter Elliot states that a variety found in red soil is much redder in colour than that inhabiting the black land. The skull is considerably smaller, according to Dr. Anderson, than that of the Bengal Nesokia, N. Blythiana, of the same age, from which it is also distinguished by its more outwardly arched malar process of the maxillary, by its considerably smaller teeth and long but less open anterior palatine foramina. The brain case is also relatively shorter and more globular than that of Nesokia Blythiana.
SIZE.—Head and body, about 7 inches; tail, 6½ inches.
The habits of this rat are similar to those of the Bengal species, to which I will allude further on, and it has the same way of taking to water when pursued.
Jerdon says that this rat is most destructive to tea-trees, biting the roots just below the surface, more, he believes, because they happen to come in the way of their burrows than to feed on them.
Sir Walter Elliot writes: "In its habits it is solitary, fierce, living secluded in spacious burrows, in which it stores up large quantities of grain during the harvest, and when that is consumed lives upon the huryale grass and other roots. The female produces from eight to ten at a birth, which she sends out of her burrow as soon as they are able to provide for themselves. When irritated it utters a low grunting cry, like the bandicoot. The race of people known by the name of Wuddurs, or tank-diggers, capture this animal in great numbers as an article of food, and during the harvest they plunder their earths of the grain stored up for their winter consumption, which in favourable localities they find in such quantities as to subsist almost entirely upon it during that season of the year. A single burrow will sometimes yield as much as half a seer (1 lb.) of grain, containing even whole ears of jowaree (Holchus sorghum)." Sir Walter Elliot goes on to give a most interesting account of the construction of the burrows of this animal.
