Miller (Proc. Acad. Nat. Sci. Philadelphia, 1902, p. 390, September 3,1902) based the name Pipistrellus cinnamomeus on a skin and skull of a vespertilionid bat obtained on May 4, 1900, at Montecristo, Tabasco, Mexico, by E. W. Nelson and E. A. Goldman. A single specimen was available to Miller when he proposed the name P. cinnamomeus . Dalquest and Hall (Jour. Mamm., 29:180, May 14, 1948) reported three additional specimens collected in 1946 by W. W. Dalquest on the Río Blanco, twenty kilometers west-northwest of Piedras Negras, Veracruz, Mexico. No other published information concerning this species is known to us, although the name has, of course, appeared in regional lists, for example in the List of North American Recent Mammals, 1923 (Bull. U. S. National Museum, 128:75, April 29, 1924) by Gerrit S. Miller, Jr.
Additional specimens, nevertheless, are known. Two collected on April 18 and 20, 1903, at Papayo, Guerrero, by Nelson and Goldman, are in the Biological Surveys Collection in the United States National Museum. A skin, probably of this species, for which the skull cannot now be found, was taken on October 27, 1904, at Esquinapa, Sinaloa, by J. H. Batty and is in the American Museum of Natural History. This is the skin referred by Miller and Allen (Bull. U. S. Nat. Mus., 144:100, May 25, 1928) to Myotis occultus . Three additional specimens, each a skin with skull, were collected twenty kilometers east-northeast of Jesús Carranza, at 200 feet elevation, Veracruz, by Walter W. Dalquest, two on April 13, 1949, and one on May 16 of the same year. These are in the Museum of Natural History of the University of Kansas, as also are the three previously reported by Dalquest and Hall ( loc. cit. ). A total of ten specimens, from five localities, all in Mexico, thus is accounted for.
