AMERICAN BATS OF THE GENERA MYOTIS AND PIZONYX 23 



collected at Fort Mohave ("Majaor" in original description; see 

 Lyon and Osgood, Catal. Type-Sp. Mamm. U. S. Nat. Mus., Bull. 

 U. S. Nat. Mus., No. 62, p. 271, January 28, 1909) on the Colorado 

 River, western Arizona. The name is preoccupied by V. viacroj)tis 

 Gould, 1854, for an Australian bat. 



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

 33, p. 385, April 20, 1914. Though it has been regarded as a full 

 species, this bat is apparently nothing else than true Myotis nigricans. 

 Some of the specimens are less dark than usual, but we are unable to 

 define the form. The type locality is Maripa, Rio Caura, Venezuela. 



Melanorhinus (Vespertilio) Merriam, North Amer. Fauna, No. 3, 

 p. 46, September 11, 1890. This appears to be the valid name for the 

 form of Myotis subulatus Say (not of H. Allen and subsequent 

 writers) of the southwestern United States and Mexican border. 

 The type came from San Francisco Mountain, Arizona, and has been 

 generally regarded as a specimen of M. colifornieus. 



Mexicanus {Vespertilio) Saussure, Rev. et Mag. de Zool., ser. 2, 

 vol. 12, p. 282, 1860. This is the first name applied to the large 

 richly colored Mexican race of Myotis calif ornicus. The type was 

 said to have come from " les terres chaudes de la province de Mexico." 



Micronyx {Myotis) Nelson and Goldman, Proc. Biol. Soc. Wash- 

 ington, vol. 22, p. 28, March 10, 1909. A name based on the Lower 

 Californian form of Myotis evotis, apparently not distinguishable 

 from M. evotis chrysonotiis. 



Milleri {Myotis) Elliot, Publ. Field Columbian Mus., zool. ser., 

 vol. 3, p. 172, April, 1903. This is the only name applied to a 

 peculiar local form, related to Myotis evotis but apparently a distinct 

 species, known only from a few specimens taken in the San Pedro 

 Martir Mountains, Lower California. 



Mundus {Vespertilio) H. Allen, Proc. Acad. Nat. Sci. Philadelphia, 

 1866, p. 280. An examination of the specimen on which the descrip- 

 tion of this species was based, shows it to be an immature example of 

 Myotis albescens Geoffroy. It came from Maracaibo, Venezuela. 



Nesopolus {Myotis) Miller, Proc. Biol. Soc. Washington, vol. 13, 

 p. 123, April 6, 1900. This is the only name given to the form of 

 Myotis nigricans inhabiting the island of Curagao. 



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

 33, p. 384, April 20, 1914. A misprint for nesopolus. 



Nigricans {Vespertilio) Maximilian zu Wied, Beitr. z. Naturg. 

 Brasil, vol. 2, p. 266, 1826. This is the first valid name applied to 

 the common small blackish Myotis of tropical South America. The 

 type was from the Rio Iritiba, Espirito Santo, Brazil. 



Nitens {Vespertilio) Wagner, Schreber's Saugthiere, suppl., vol. 5, 

 p. 810, pi. 51, fig. 4, 1855. Referred by Trouessart to Myotis., and
