The first mention of bats in Nebraska possibly was by Harrison Allen, in his “Monograph of the Bats of North America” (1864:14, 20, 30, 35, 42), who listed _Nycticejus crepuscularis_ [= _Nycticeius humeralis_], _Lasiurus borealis_, _Scotophilus carolinensis_ and _Scotophilus fuscus_ [both = _Eptesicus fuscus_], and _Scotophilus noctivagans_ [= _Lasionycteris noctivagans_], as collected in “Nebraska” (then Nebraska Territory) by J. G. Cooper. Henry W. Setzer (in _litt._) reports that none of the bats collected by Cooper now exists in the United States National Museum and that no data pertaining to any of them are available except that a single specimen of _Nycticeius humeralis_ was traded to the British Museum in 1866. Cooper journeyed through parts of the present state of Nebraska in the summer and autumn of 1857 and, judging from Taylor’s (1919:72-80) report of Cooper’s travels, this was the only time he entered any part of Nebraska Territory. The writers are of the opinion that the specimens in question probably were collected in Nebraska; but since Allen listed no exact localities or dates of collection and since the specimens and data pertaining to them are not now available, we have not included them here as Nebraskan records.
