Cynocephalus (Nycticea). Le Coute, McMiirtrie's Guvier, Animal 

 Kingdom, I, p. 432, 1831. This is a free-tailed bat, the common Nyc- 

 Uiiomus of the southeastern United States. 



Domesticus (Vespertilio). Green, Doughty's Gabinet of Natural His- 

 tory, il, p. 290, 1832. The description refers without much doubt to 

 Myotis lucifugus Le Gonte, named only one year previously. Type 

 locality a village in western Pennsylvania near a stream which enters 

 the Ohio a few miles from Pittsburg. 



Dutertreus (Vespertilio). Gervais, in Ramon de la Sagra's Hist, de I'De 

 de Guba, Mamm., i^. 6; Atlas, Tome II, 1840. This is Vespertilio fus- 

 cus cuhensis (Gray), as shown by the number of teeth, 32, and by the 

 size, forearm 47 mm. 



Erythrodactylus (Vespertilio). Temminck, Monographies de Mamm., 

 II, p. 238 (13me Monogr.), 1835-41. Temminck describes his Vesper- 

 tilio erythrodactylus as a bat with short, roundish ears, long tail, inter- 

 femoral membrane hairy on basal half above, four upper incisors, and 

 general reddish-brown color.^ 



This is a combination of characters normally possessed by no known 

 North American bat. The type is said to have come from the neighbor- 

 hood of Philadelphia. It is probably Pipistrellus suhflavus reddened 

 by alcohol (see p. 8). 



Evotis (Vespertilio). H. Allen, Monogr. North Am. Bats, p. 48, 1864. 

 Tliis is the first name for the large eared Myotis of the western United 

 States. 



Exilis (Vespertilio). II. Allen, Proc. Acad. Nat. Sci. Phila., p. 283, 

 1866. Vespertilio cxilis is a synonym of Myotis ealifoniicus. The type 

 came from Gape St. Lucas.

 Berlin (1870), p. 908, 1871. Peters's Atalapha frantzii from Gosta 

 Eica is the small, scantily furred soutliern race of Lasiiirus horealis.
