type probably came from the Far East rather than, as supposed, 

 from Montevideo, Uruguay. 



Polythrix {Vespertilio) I. Geoffroy, Ann. des Sci. Nat., ser. 1, vol. 3, 

 p. 443, 1824. There is little in the original description that would 

 certainly identify this bat, which in size is said to be slightly larger 

 than the common pipistrelle of Europe, its color " brun-marron 

 tres f once " above ; below, the same with a slight touch of grayish ; 

 forearm 38 mm. The original specimens were sent from southern 

 Brazil with others from Rio Grande do Sul and Minas Geraes. 

 Gervais examined the types in 1855 and referred them to Myotis 

 (as a subgenus) since they appeared to have teeth back of the 

 canines. He describes their pelage as " brun, legerement nuance de 

 roussatre." The color and size indicate that they are specimens o* 

 Myotis ruber, to the synonymy of which the name poJythiiic may 

 therefore be referred. 



Punensis {Myotis) J. A. Allen, Bull. Amer. Mus. Nat. Hist., vol. 

 33, p. 383, July 9, 1914. Four specimens of Myotis, two from Puna 

 Island, Ecuador, and two from Daule on the neighboring mainland 

 were regarded by J. A. Allen as distinct from M. nigricans. Their 

 somewhat pale color appears to us to be within the limits of indi- 

 vidual variation in true nigricans. 



ftuercinus {Myotis californicus) H. W. Grinnell, Univ. California 

 Publ. ZooL, vol. 12, p. 317, December 4, 1914. Mrs. Grinnell en- 

 deavored to restrict the name M. californicus to the form of the 

 small-footed brown bat occurring in "that portion of California 

 north of about latitude 36 degrees and west of the desert divides," 

 and applied the new term quercinus to the form of southern and 

 southwestern California. Unfortunately, however, Audubon and 

 Bachman's original characterization of the color of californicus as 

 "light yellowish brown" hardly applies to those specimens north 

 and west of 36° so well as to those south of it, and Miller in 1897 

 had already described the darker northwestern animal as caurinus. 

 It seems best therefore to regard quercinus as a synonym of cali- 

 fornicus. The type locality is Seven Oaks, San Bernardino County, 

 Calif. 



Ruber {Vespertilio) E. Geoffroy, Ann. Mus. d'Hist. Nat. Paris, 

 vol. 8, p. 204, 1806. This is the first name applied to the large russet 

 or reddish-brown Myotis of South America, the " chauve-souris 

 onzieme " of Azara. It is assumed that Azara's description, on which 

 the name is based, was taken from Paraguayan specimens. 



Salarii {Vespertilio) F. Cuvier, Nouv. Ann. Mus. d'Hist. Nat. Paris, 

 vol. 1, p. 15. 1832. The original description of this bat, based on a 

 specimen sent by Milbert from the vicinity of New York, is not 

 sufficient for a clear determination. Apparently, however, it applies 

 to Myotis lucifugus.
