~Artibeus hirsutus~ Andersen.--One specimen (25053, in preservative) of
a series from 1/4 mi. W Aduana (27 deg.02', 109 deg.03'), 1600 feet, Sonora,
was cited by Hall and Kelson (1959:136) and reproductive data from two
skins (24841-24842) were mentioned earlier by Cockrum (1955:490). In
addition to these three specimens the series includes 20 specimens in
preservative (25052, 25054-25072). All were collected on May 16, 1948,
by J. R. Alcorn. Number 25070, on deposit in the Institute of Biology
in Mexico City, and two others (25053-25054) are not on hand as I write
this, and have not been examined by me. _Artibeus hirsutus_ has
recently been found in northern Sinaloa and in southwestern Chihuahua.
Three males (75208-75210) from El Fuerte (26 deg.24', 108 deg.41'), Sinaloa,
were obtained on December 10, 1957, by William L. Cutter. Four
specimens (79441-79444, 2 males and 2 females) were captured in mist
nets on the north bank of the Rio Septentrion, 1-1/2 mi. SW Tocuina
(27 deg.07', 108 deg.22'), 1500 feet, Chihuahua, on July 18, 20, and 21, 1958,
by Kenneth E. Shain and me. I captured another (79445, a male) in a
hand net in an abandoned, horizontal mine shaft on the north side of
the Rio Batopilas, at about 3500 feet elevation, across the canyon from
the village of La Bufa (27 deg.09', 107 deg.33'), Chihuahua, on July 10, 1958.
Eight specimens (12406-12413) in the Museum of Natural History at the
University of Illinois were collected on July 22 and 23, 1956, in Santo
Domingo Mine (26 deg.55', 109 deg.05'), 7 mi. SW Alamos, Sonora, by W. Z.
Lidicker, W. H. Davis, and J. R. Winkelman. Eight specimens (9981-9988)
in the Los Angeles County Museum were collected on July 26, 1953, by
Kenneth E. Stager, 5 mi. W Alamos in an old mine tunnel at Aduana. One
(36581) of six specimens (36581-36586, 4 males and 2 pregnant females)
from 2 mi. ENE Tala (20 deg.39', 103 deg.40'), 4500 feet, Jalisco, was
reported by Hall and Kelson (1959:136); the locality being erroneously
cited as 8 mi. ENE Tala. These six specimens were collected by J. R.
Alcorn on February 28, 19
