ilers unequally trlfid. Snout plain, nose williout appendatjcs. Ears separated, 
auriculated. "rail nnioronate.— This genus appears to differ from all those of 
GeofProy and Cuvier, among the extensive tribe of Bats. The name means house- 
flyer. 
'2. Kptesicus melanops. Fallowisn brown above, pale beneath, face, ears, wings, 
feet and tail blackish ; ears oval, shorter than the head and wrinkled ; tail naked, 
one-third of total length, mucronc one-sixth of the tail ; posterior toes ciliate,-Not 
uncommon in Kentucky, Indiana, <^c. total length four and an half inches. I 
bad noticed it under the name of Vespertilio phuiops in the American Magazine, 
vol. 3d. It comes often iii tlie house at night. 
3. Eptesicus myda-i. Fulvous above, grey beneath; wings, ears and tail, pale 
brown, sliafts whitish ; ears double the length of tlie head; tail naked, slightly 
mucronate, neaiiy as long as the body. — 1 have observed it in the barrens ot Ken- 
tucky flying in the houses. Total length three inches, of which tiie tail includes 
five-twelfths. Ears three-quarters of an inch long. I mentioned it under the 
name of Vesp. mydas in my account of the Bats of the western states, (Am. Mag. 
v. 3). I have .since instituted two other genera with tliem, Hi/pexodon and J^'iicti- 
ceius (Prodr. 70 N. (;. An) ; the others are probably Atalaphes. I know already 
fifteen species of Bats in the United Stales, almost uU new ones. 
4. Mrphiiiainierrnpla. Brown, with two short parallel white streaks on the 
head, and eight on tlie back, the four anterior ones equal and parallel, and the 
four posterior ones rectangular, angles in opposite directions. — .\ rare species, a- 
bout one foot long, inhabiting Louisiana. Tiie four rectangular streaks of the 
rump are very singular ; the anterior pair begins on eacii side towards the middle 
of the dorsal streaks, and reaching beyond them in a parallel line, become trans- 
versaily angular, forming an unequal right angle facing the dorsal streaks ; while 
the posterior pair forms two complete right angles facing the sides of the rump, 
their anterior lines being parallel and longitudinal. 
5. Spalax vittattn. Fallow above with three longitudinal, broad and brown 
streaks, white beneath. — It lives in the barrens and woods of Kentucky, where it 
is called mole-rat : length seven inches, it has no tail whatever ; back bent, head

7. Gerbillus leoiiurus. Entirely of a fine fallow; ears eUiptic, aa long as the 
head, white inside ; tail as long as the body, black, tipt with a fallow tuft— It 
lives in the woods of Kentucky, Indiana, &c." Eyes small. It rather jumps than 
runs, while the foregoing species is oftencr seen running than jumping. 
8. CricetusfascialHs. Ilufous, with about ten transversal black streaks over 
the back, legs with some similar streaks; tiil rather shorter ilian the body, slen- 
der and with black rings: pouches external, flaccid. — This is tlie Hamster of the 
barrens of Kentucky and the western states ; it has a tlilck body, the head 
like a dog, small eyes and ear.s, these oval and acute, the forehead rounded and 
the pouches hanging like bags. 
9. Lt'inmusviitatus. liufous, with five longitudinal v.'h.ite streaks on the back,

while in the winter it burrows under the snow, at the surface of the ground, to 
feed on tender grass.
