The head of this bat (_fig. 120._) is very peculiarly constructed; the nose is sunk in the front, and, contrary to all other animals, it has not its nostrils divided by a partition, but are placed on the sides of a kind of gutter entirely open from one end to the other; the exterior edges of them join above the upper lip, forming a cavity from thence to the front, where it terminates with a deep hole covered all round with long hairs. It has long narrow ears; the hair on the top and hind part of the head, along the neck, back, tail, and shoulders, is of a reddish brown, and all the remainder is of a yellowish white; the membrane of the wings and tail have a kind of mixture of black and reddish brown and its claws are yellow. Its body is about an inch and a half long, and its wings extend to about seven. _Engraved for Barr's Buffon._ [Illustration: FIG. 121. _Polatouch_] [Illustration: FIG. 120. _Bearded Bat_] [Illustration: FIG. 122. _Swiss Squirrel_] [Illustration: FIG. 123. _Palmist_] THE STRIPED BAT. This bat is very small, has a short nose and broad ears, bending forward; it is of a whitish yellow colour, excepting under its throat, breast, and belly, which is a light blue, with a yellow shade; the tail, and membrane of the wings are a mixture of yellow and brown. THE POLATOUCH. I have chosen to continue the name this animal bears in Russia, its native country, rather than to adopt those vague and uncertain ones since appropriated to it, such as, the Flying-rat, Flying-squirrel, &c.
