APPENDIX. Y3 



Total length, 4i inches. I had noticed it under the head of V. phaiops, in 

 the American Magazine, vol. III. It comes often in the house at night. 



3. Eptisecus mydas. — Fulvous above, gray beneath ; wings, ears, and tail 

 pale brown; shafts whitish ; ears double the length of head; tail naked, 

 slightly mucronate, nearly as long as the body. — I have observed it in the 

 barrens of Kentucky, flying in the houses. Total length three inches, of 

 the tail includes five-twelfths. Ears three-quarters of an inch long. I 

 mentioned it under the name of V. midas, in my account of the Bats of the 

 Western States (Ann. Mag. vol. Ill), I have since substituted two other 

 genera of them, Hypexodon and Nynticpjus (Prod. 70, N. G. An.) ; the 

 others are probably Atalnphes. I know already fifteen species of bats in 

 the United States — almost all new ones.

Major Leconte. — Cuv. An. Kingdom (McMurtrie's ed.), 431. 



I. 



Vespertilio carolinensis, Geof. — Anterior upper fore teeth sub-simple, 

 larger than the posterior. Remarkable for a strong odor resembling that 

 of a fox. 



V. lucifugus, L.C. — Anterior upper fore teeth bilobate ; body 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, 2^ inches ; tail 1^ inches. 



V. noctivagnns, L.C. — Anterior upper fore teeth bilobate, the posterior 

 sub-simple ; color black or dusty cinereous ; hair on the back and belly 

 tipped with gray ; ears short, naked, roundish ; tragus short and roundish ; 

 «ose sub-bilobate ; tail projecting a little beyond the interfemoral mem- 

 brane, which is hairy. Length, 2^ inches ; tail, 1| inches. 



II. 



Add Plecotus macrotis, L.C. — Upper fore teeth four, trilobate, distant 

 by pairs, the posterior smaller ; ears very long, pointing forwards ; tragus 

 subulate, half the length of ears. 



III. 



Nycticejus noveboracensis. — Easily known by its short and round ears, 

 and by the interfemoral membrane being hairy and including the whole 

 of the tail. There is a white spot at the insertion of the wing, and another 

 at the base of the thumb ; these marks are constant. This species varies 

 much in color, and has been called V. lasiurus, Schreb., V. monachns by 

 some, and is figured in Wils. Orn. VI, pi. 4, whence it has been quoted by 

 M. Cuvier as the Taphozous.
