Remarks.—Two bats of this subspecies were found in the quarry in Sarpy County on December 30, 1949. None was found on subsequent visits to the quarry, although three other species of bats have been found there in large numbers. These specimens appear to be the first actual records of M. l. lucifugus in the state, although Swenk (1915:854, and in subsequent lists) reported it as "uncommon eastwardly".
One of these bats, a male (KU 35076), possesses a peculiar dental abnormality. Both of the second upper premolars (P3) are lacking, although the mandibular dentition is normal. This condition has been reported previously for this species by Frum (1946:176) in specimens from West Virginia.

Distribution in Nebraska.—Northern and western Nebraska.
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.
