Synonymy and History—This bat was described by Merriam 
(1890, pp. 31-32) from a specimen taken at Alhambra, Los Angeles 
County, California, under the name Molossus californicus. Miller 
(1906, p. 85) made Merriam’s Molossus californicus the type species 
of the new genus Humops, distinguished from the nearly related 
genera Molossus and Promops by reason of its arched rather than 
domed palate and less well-developed sagittal crest. 
Distribution.—Miller (1907, p. 256) figures the skull of a specimen 
taken at Tucson, Arizona, and Bailey (1905, p. 216) records the 
capture of a specimen of LZ. californicus at the bottom of Pump 
Cafion, near Langtry, Texas. J. Grinnell (1913b, p. 284) gives the 
range of this bat in California as follows: ‘‘Lower Sonoran zone of 
southern California; most numerous in the San Diegan district, but 
noted also on the Colorado Desert, and in the San Joaquin Valley, 
in Kern and Fresno counties (Mus. Vert. Zool.) ; northernmost station, 
Fresno.’’ The basis of the latter record was two specimens seen in 
a taxidermist’s shop in Fresno, and stated to have been caught in 
the courtyard of that city. (See map, text-fig. H.)
