Additional Records and Extensions of
Known Ranges of Mammals From Utah

The Museum of Zoology, University of Utah, contains approximately5000 specimens in addition to those available to Durrant(1952) when he prepared his account of the "Mammals of Utah,Taxonomy and Distribution." Study of this material discloses twokinds of mammals not heretofore known to occur in Utah, and extendsthe known limits of occurrence of many others as is set forthbelow in what may be thought of as a supplement to the aforementionedreport of 1952.
Our study was financed in part by a grant from the NationalScience Foundation.
Sorex vagrans obscurus Merriam. Dusky Shrew.—Twelve specimensare available from the Abajo Mountains and Elk Ridge, SanJuan County, Utah, as follows: North Creek, 6 mi. W Monticello,8300 ft.; 1 mi. S Twin Peaks, 9500 ft.; Kigalia R. S., 8000 ft.; andGooseberry R. S., 8250 ft. Previously, the only known specimensfrom east of the Colorado River in Utah were from the La Sal Mountainsin extreme eastern Grand County and extreme northern SanJuan County. These twelve specimens extend the known area ofoccurrence of the species in Utah approximately 80 miles to thesouth, and indicate that this shrew occurs throughout the state infavorable habitats.
Sorex palustris navigator (Baird). Water Shrew.—An individualwas observed by M. Raymond Lee at North Creek, seven mileswest of Monticello, Abajo Mountains, 8000 feet, San Juan County,on July 10, 1954. Usually we are extremely reluctant to recordsight records, but do so in this instance because the water shrewis so distinctive that it can be readily recognized and because theoccurrence extends the known range approximately 80 miles southwardin Utah. This individual was observed at close range whileswimming and foraging in North Creek, and there can be no doubtof its identity.
Myotis yumanensis yumanensis (H. Allen). Yuma Myotis.—Durrant[Pg 72](1952:43) reported this subspecies from Utah on the authorityof Hardy (1941:289) who had specimens from two localities inextreme southwestern Utah. Durrant (1952:41) referred specimenNumber 6784, from Willow Creek, 25 miles south of Ouray,Uintah County, to Myotis lucifugus carissima. Restudy of thisspecimen reveals that it is Myotis yumanensis yumanensis. Thisidentification has been corroborated by Dr. Philip H. Krutzsch,University of Pittsburgh, Pennsylvania, and extends the knownrange of the subspecies M. y. yumanensis approximately 300 milesnortheastward in Utah. See also Krutzsch and Heppenstall (1955:126)who record specimens from 2 mi. SW Jensen.
Myotis subulatus melanorhinus (Merriam). Small-footed Myotis.—Thisbat previously was known from only seven localities in Utah,which indicated that it occurred in only the western and southernareas of the state. Four additional records are now available fromthe following localities: Logan Canyon Cave, 15 miles north ofLogan, Cache County; Weber College Campus, Ogden, WeberCounty; University of Utah Campus, Salt Lake City, Salt LakeCounty; Six Mile Canyon, 3-1/2 miles
