Habits, 8c.—Pallas states that this ground-squirrel burrows in woody districts, in small hillocks, or near the ruls of trees; but never makes its nest in the trunks or branebes of trees, like the common squirrels, although, when frigh:ened from its hole, it climbs with ease, speedily making its way from branch to branch. The nest is reached by a winding tunnel, and there are generally two or three lateral chambers, for the stowage of winter food. It is allied in its habits to the hamster and citillus (Spermophilus), is 009nected with the latter by the convexity of its nose, and has cheek •pouches, but differs altogether in its manners frva the tree-squirrels. The head is longer than that of the common squirrel; the ears are rounded and without tufts: the roundish hairy tail is seldom turned up; the body is slender, the extremities are shorter than those of the common squirrel, and the fur is very short, and not so fine. Its habits are diurnal, it does not become torpid in winter, ard in these respects it approaches the true squirrels. It is ou easily tained.
Dr. Richardson remarks that the Sciurus (Tamias) Lys teri of Ray, the Hackee of the United States, Ohinoia of the Hurons, Striped Dormouse of Pennant, is considered by the author of the above description, and subsequent writers,
