Urocyon cinereoargenteus scottii Mearns. Gray Fox.—One skull, No. 10,240, from mouth of Birch Creek, Deep Creek Mountains, Juab County, extends the known geographic range 50 miles east from Cherry Creek Canyon, Nevada (see Hall, 1946:241). This record indicates that the species occurs in the mountainous areas on the western margins of Pleistocene Lake Bonneville, and extends the known range in Utah approximately 150 miles northward. Furthermore, this record proves that the gray fox occurs as far north in western Utah as it does in eastern Nevada, but to date none has been obtained from the mountains within the basin of the ancient lake, even though some of them are not far removed from the Deep Creek Mountains.
Lutra canadensis nexa Goldman. River Otter.—River otters are rare in a semi-arid state like Utah, and few have been preserved as scientific specimens. Durrant (1952:436) had access to but one skull from an immature animal from the Raft River Mountain area in northwestern Boxelder County. At present there are two complete specimens (skins, skulls and skeletons) in the collection of the University of Utah. They were trapped by an employee of the Utah State Fish and Game Department, and were donated to the University of Utah by J. Perry Egan, Director of the above mentioned department. They are nos. 8854 and 8855, and are from the Raft River, 2 miles south of the Utah-Idaho border, Boxelder County.
Alces americanus shirasi Nelson. Moose.—The moose is rare in Utah, and to date records of its occurrence have been based solely upon sight records. There are, nevertheless, two specimens preserved. One is a young bull (skull only) from Farmington Canyon, Davis County, in the collection of Weber College, Ogden, Utah. The other is one antler (No. 10,745) of a young bull from Henrys Fork, 16 miles south of the Utah-Wyoming border, Summit County, and it is in the collection of the University of Utah. This large cervid apparently is increasing in numbers in the state. Dale Jones of the Utah State Fish and Game Department reported to us that a herd of 25 animals was observed in 1954, in the vicinity of Haydens Peak, Bear River Drainage, Summit County. A cow and a calf were seen in the vicinity of Strawberry Reservoir, Wasatch County, in 1951, by employees of the same department. This latter locality is the most southern and eastern point of their known occurrence in Utah.
Ovis canadensis canadensis Shaw. Mountain Sheep.—Formerly, the mountain sheep was not known to occur in the La Sal Mountains in Grand and San Juan counties. On October 23, 1954, a two year old ram, No. 10,906, was killed by a deer hunter at a locality 1-1/2 miles north of La Sal, La Sal Mountains, San Juan County. This constitutes the first complete specimen (skin and skull) of a mountain sheep from Utah. According to Harold Crane, of the Utah State Fish and Game Department, this ram was running with a herd of mule deer, and was the only mountain sheep that was seen. The ram was confiscated and given to the Department of Zoology, University of Utah, for preservation as a scientific specimen.
