County, Idaho (Davis, 1939:117).

Pipestrellus hesperus hesperus (H. Allen). Western Pipistrelle.—Heretofore, the northernmost known specimens of this bat from Utah were from Old Lincoln Highway, 18 miles southwest of Orr's Ranch, Tooele County. Specimen Number 7531 is now available from cliffs NE [3 mi.] Ogden, Weber County, and extends the known range of this species in Utah approximately 100 miles northeastward. This pipistrelle probably inhabits all of northern and northwestern Utah in suitable habitats. This probability is supported by Davis' (1939:120) report of a specimen from Salmon Creek, eight miles west of Rogerson, Twin Falls County, Idaho. See also Krutzsch and Heppenstall (1955:127) who record a specimen from, eastern Utah as far north as, Desert Springs which is 10 mi. SW Ouray, Uintah County.

Corynorhinus rafinesquii pallescens Miller. Long-eared Bat.—Formerly, the northernmost record of the long-eared bat in Utah was from east of Springville, Utah County. Specimens are now available from Goldhill, Tooele County, and from South Fork, Ogden River, Weber County. Professor J. S. Stanford, Department of Zoology, Utah State Agricultural College, informed us (by letter) that this bat is the common cave bat in Logan Canyon, Cache County. This northern extension of known area of occurrence of approximately 100 miles indicates that it probably is state-wide in distribution in suitable habitats. It can be inferred from Hall (1946:161) that the range of C. r. intermedius in Nevada extended northeastward into northwestern Utah, and Davis (1939:124) reported specimens from Bingham and Bannock counties, Idaho, that he referred to the above mentioned subspecies. This led Stanford to comment (in litt.) that bats of this species from northern Utah in Cache County might be C. r. intermedius. Insofar as we are aware, C. r. pallescens differs from C. r. intermedius only in being slightly paler. Our specimens from Goldhill and South Fork of the Ogden River are not beyond the range of color of specimens from elsewhere in the state that are referable to C. r. pallescens. Inasmuch as specimens are not available from Logan Canyon, we deem it best pending the acquisition of specimens from that locality to refer all members of this species from Utah to the subspecies C. r. pallescens.

Marmota flaviventer nosophora Howell. Yellow-bellied Marmot.—Durrant (1952:101) did not indicate that any species of the genus Marmota occurred on the mountains within the basin of Pleistocene Lake Bonneville. Furthermore, he commented (op. cit.:502) upon the dearth of sciurids within this basin. One specimen, No. 10,905, of the subspecies M. f. nosophora has been taken from South Willow Canyon, 10,000 feet, base of Deseret Peak, Stansbury Mountains, Tooele County. This specimen is noteworthy not only in that it extends the known range of this kind of mammal 50 miles to the west in Utah, but in that it is well within the basin of the ancient lake. The marmot is common in the Wasatch Mountains on the eastern mainland of Lake Bonneville, but to date has not been found on the Oquirrh Mountains immediately to the west. The Oquirrh Mountains are interposed between the Stansbury and Wasatch mountains. The presence of the marmot on the Stansbury Mountains indicates that it probably occurs also on the Oquirrh Mountains.

Citellus beldingi crebrus Hall. Belding Ground Squirrel.—Durrant (1952:113) had only two specimens of this ground squirrel from Standrod, Boxelder County. Additional specimens have been obtained from the following localities in northwestern Boxelder County: Grouse Creek, Park Valley, Grouse Creek Mountains, 12 miles northwest of Grouse Creek, and Goose Creek. C. b. crebrus now is known to inhabit all the major drainages of the Raft River,
