Gary Some Unrecorded Colorado Mammals. 27 



Perodipus longipes (Merriam). 



The Moki kangaroo rat is tolerably common in the desert part of the 

 lower Grand Valley, from the Utah line east at least to Grand Junction. 

 A fine male was collected three miles northwest of Fruita, Mesa County, 

 September 27, 1906. Four immature specimens from Grand Junction are 

 also in the Biological Survey collection. 



Perognathus apache Merriam. 



A pocket mouse collected on the sandy desert three miles northwest of 

 Fruita, Mesa County, September 28, 1906, is referable to this species. 

 Another specimen, taken at Balzac, west of Rifle, Garfield County, Octo 

 ber 4, 1906, is much larger, but of similar coloration, and its affinities are 

 clearly with apache. 



(?) Perognathus callistus Osgood. 



Numerous signs of a small or medium sized pocket mouse were noted 

 in bunches of prickly pear (Opuntia polyacantlut) , in the valley of Snake 

 River, a few miles southeast of Sunny Peak, in August, 1906. Specimens 

 were not secured, owing to the extreme abundance of white-footed mice. 

 The Snake River pocket mice are tentatively recorded as P. callistus be 

 cause of their proximity to the type locality, Kinney Ranch, Sweetwater 

 County, Wyoming, which is only 40 miles to the northwest. No other 

 evidences of pocket mice were observed north of the Grand River Valley. 



Spilogale gracilis saxatilis Merriam. 



The little spotted skunk is generally reported from the warm desert val 

 leys entering Colorado from the west. Sunny Peak, Routt County, seems 

 to be the eastern limit of its dispersion in the Snake River Valley ; while it 

 is common at Rangely, on White River ; and in Lily Park, at the con 

 fluence of the Snake and Bear rivers. In the Grand Valley the spotted 

 skunk probably occurs as far east as Glenwood Springs, since Mr. Fred 

 Baker, a taxidermist of that place, reports that he has recently handled 

 several skins taken between Newcastle and Glenwood Springs. 



A male specimen from Grand Junction (collection Biological Survey, 

 November 3, 1895, A. H. Ho well), and one from Coventry, Montrose 

 County, taken in 1906 (collection E. R. Warren), have been recorded 

 recently as saxatilis* 



Myotis calif ornicus (Aud. and Bach.). 



In his recently published list of Colorado mammals,f E. R. Warren in 

 eludes this species on supposition, without citing actual records of capture. 

 A specimen in the Biological Survey collection from the southern end of 

 the San Luis Valley shows that this bat reaches extreme southern Colo 

 rado. It is an adult male, and was taken 7 miles east of Antonito, Conejos 

 County, September 1, 1904, at 8,000 feet.
