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.

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.
