The same author, Rzaczynski, mentions another animal, called by the Russians _pouch_: it is larger than the domestic rat; its muzzle is long, it burrows, and commits depredations in the gardens, &c. There were such numbers near Suraz and Volhinia, that the inhabitants were obliged to abandon the culture of their gardens. This pouch is possibly the same as what Seba calls the _Norwegian rat_, of which he gives a figure and description. 7. THE PEROUASCA. There is also in Russia and Poland, especially in Volhinia, an animal which the Russians call _perewiazka_, and _przewiaska_ by the Polanders, a name we may translate the _girdled weasel_. This animal is not so big as the pole-cat; it is covered with a whitish hair, transversally striped with a yellowish red, which appears like so many girdles. It lives in the woods, and burrows in the earth; its skin is sought after and makes a very beautiful fur. 8. THE SOUSLIK. There is found at Casan, and in the provinces watered by the Wolga, and even in Austria, a small animal called _souslik_ in the Russian language, which furnishes a beautiful fur. In figure and shortness of tail, it greatly resembles the short-tailed-field-mouse; but what distinguishes it from the mouse or rat kind, is its coat, which is in every part sprinkled with small spots of a glossy and shining white; these spots are exceedingly small, and placed at a little distance from each other; they are more apparent upon the loins, than on the shoulders and head. Mr. Pennant, an English gentleman, thoroughly versed in Natural History, favoured me with one of these sousliks, which had been sent him from Austria, as an animal naturalists were not acquainted with. I soon recognised it to be the same as that of which I had a skin in my possession, and of which M. Sanchez had furnished me with the following account. "The rats called _sousliks_, are taken in great numbers in the salt vessels in the river _Kama_, which descends from Solikamski, where the salt pits are, and falls into the Wolga above the town of Casan. The Wolga from Simbuski to Somtof, is covered with these salt vessels, in which these animals are taken, as well as in the lands which border on those rivers. They have been named _souslik_, that is, dainty-mouthed, because they are very fond of salt." SUPPLEMENT.
