_Records of occurrence._--Specimens examined, 9, as follows: CHERRY CO.: Valentine, 1 (Univ. Nebr. Dept. Zool.). SHERIDAN CO.: Rushville, 1; 15 mi. N Rushville, 2. SIOUX CO.: Agate, 1 (Univ. Kansas Mus. Nat. Hist.); Monroe Canyon, 5-1/2 mi. N, 2-1/2 mi. W Harrison, 2 (Nebr. Game, Forestation and Parks Comm.); Warbonnet Canyon, 2 (Univ. Nebr. State Mus.). Additional records: DAKOTA CO.: Crystal Lake, 1 (Stephens, 1945:92). DAWES CO.: Chadron, 1 (Miller and Allen, 1928:169). SIOUX CO.: Antelope Township, 1 (Quay, 1948:181); Sugarloaf Township, 1 (Quay, 1948:181). _Remarks._--This bat is common along the Niobrara River in the northwestern part of the state. Stephens (_loc. cit._) reports taking a bat of this species in Dakota County in the northeastern corner of Nebraska. This specimen was sent to Swenk at the University of Nebraska for positive identification and was, according to Stephens, deposited in the Swenk collection. No trace of the specimen can be found at the present time. It is here assigned to _M. s. subulatus_. _M. s. subulatus_ has been observed frequently in the Pine Ridge area, generally in association with _Eptesicus fuscus pallidus_. Two specimens were shot by us from many that were seen flying over a small clearing in the pines in northern Sioux County on August 2, 1949. Several _Eptesicus_ were also obtained there. One of us (Webb) took two of these bats from their daytime retreat in a barn north of Rushville, Sheridan County, on September 5, 1951, where _Eptesicus_ was also found. They are known to inhabit hay barns at the Ft. Niobrara Game Reserve, Cherry County, also in association with _Eptesicus_. Swenk (1908:137) reports finding two of these bats under a loose strip of pine bark in Sioux County. ~Myotis volans interior~ Miller Hairy-winged Myotis _Myotis longricus interior_ Miller, Proc. Biol. Soc. Washington, 27:211, October 31, 1914, type from Twining, Taos Co., New Mexico. _Myotis volans interior_, Miller and Allen, Bull. U. S. Nat. Mus., 144:142, May 25, 1928. _Distribution in Nebraska._--Badlands area of extreme northwestern part of state. _Records of occurrence._--Specimens examined, 2, as follows: SIOUX CO.: Warbonnet Township, 8 mi. N Harrison, 2 (Cleveland Mus. Nat. Hist.). _Remarks._--Quay (1948:181) reported finding a colony of approximately 180 of these bats in northern Sioux County in the summer of 1944. They were found in a crevice in a dry creek bed. He examined several dozen, all females, two of which were saved as specimens. The authors, while engaged in field work in this approximate locality in the summers of 1948 and 1949, were unable to locate any of these bats. ~Lasionycteris noctivagans~ (Le Conte) Silver-haired Bat _V[espertilio], noctivagans_ Le Conte, McMurtrie's Cuvier, Animal Kingdom, 1:431, June, 1831, type from eastern United States.
