Eafinesque.— Annals of Nature, 1820, 2, 3. 



1. N. sp. AtaJuphafHscata. Ears lougcr than tbe head, auricnlated and h.lackish; 

 tail three-sevt^nths of total length, jutting only by an obtuse point; body brownish 

 above, grayish beneath ; shoulders and cheeks dark brown ; hind feet blackish, hairy 

 above; wings blackish brown. Found in the northern parts of the state of New 

 York and in Vermont. Total length three and an half inches. My genus Atalaplia 

 (Prec. dec.) contain all the Bats without fore teeth; there are 3 or 4 species of 

 them in the United States all blended under the name of respcrtilio (oi- Koctiiio) 

 novehoraceutiis by the writers. 



1. N. G. Eptesicus. Four acute fore-teeth to the upper jaw, in two equal pairs, 

 separated by a great interval and a large flat wart, each pair has two unequal teeth, 

 the outsi<1e tooth is much larger and unequally bitid, the outside one much larger,' 

 inside tooth small and entire. Six fore-teeth to the lower jaw, equal very small, 

 close and truncate. Canine teeth very sharp, curved and long. Grinders un- 

 equally triful. Snout plain, nose without appendages. Ears separated, auricn- 

 lated. Tail nnicronate.— This genus appears to differ from all those of Geoffroy 

 and Cuvier, among the extensive tribe of Bats. The name means house-flyer. 



2. Eptesicus mchniops. Fallowish brown above, pale beneath, fiice, ears, wings, 

 feet and tail blackish; ears oval, shorter than the head and Avrinkled; tail naked, 

 one-third of total length, niucroue one-sixth of the tail; posterior toes ciliate.— Not 

 uncommon in Kentucky, Indiana, &c., total length, four and an half inches. Iliad 

 noticed it under tlie head of VespertiUo phaiop8,m the American Magazine, vol. 3d. 

 It comes often in the house at night. 



3. Eptesicus mijdas. Fulvous above, grey beneath; wings, ears and tail, pale 

 brown, shafts whitish; ears double the length of the head; tail naked, slightly mn- 

 cronate, nearly as long as the body.— I have observed it in the barrens of Kentucky 

 flying in the houses. Total length three inches, of which the tail includes tive- 

 twelfths. Ears three-quarters of an inch long. I mentioned it under the name of 

 Vesp. midas in my account of the Bats of the Western States, (Am. Mag. v. 3). I 

 have since instituted two other genevawiththem, Hi/jjcrodon and Xi/cticeius (Prodr. 

 70 N. G. An) ; the others are probably Atalaphes. I know already tifteen species of 

 Bats in the United States, almost all new ones.

I. 



Tespertilio carolinensis, Geoff. Anterior upper fore-teeth sub-simple, larger than 

 the posterior. Remarkable for a strong odour resembling that of a Fox. 



F. lueifugus, L. C— Anterior upper fore-teeth bilobate; bo<ly above dark brown, 

 beneath cinereous; nose sub-bilobate; face with a nakedish prominence on each side; 

 ears oblong, naked, tragus sublinear, half as long as the ears; tail projecting a little 

 beyond the membrane; length to the insertion of the tail, two inches and a quarter; 

 tail, one inch and a quarter. 



V. noctivagans, L. C. Anterior upper fore-teeth bilobate, the posterior sub-simple ; 

 colour black or dusty cinereous ; hair on the back and belly tipped with grey ; ears 

 short, naked, roundish; tragus short and roundish ; nose sub-bilobate; tail project- 

 ing a little beyond the interfemoral membrane, which is hairy ; length two inches 

 and Ave eighths; tail one and three eighths. 



II. 



Add Plecotus macrotis, E.G. Upper fore teeth four, trilobate, distant by pairs, the 

 posterior smaller ; cars very long, pointing forwards ; tragus subulate, half the length 

 of the ears. (There is another species with equally long ears, which are not united 

 on the cranium; which of these is the Megaloiis, of Raffin., it is impossible to say.)
