Merriam Jack Rabbits of the Lepus Campestris Group. 133 



with a conspicuous broad gray median band, tapering to a point and dis 

 appearing before reaching tip; white ring around eye broad and con 

 spicuous above and behind the eye, narrow below posteriorly, disappearing 

 anteriorly ; upper lip and sides of nose, including patch at base of whiskers, 

 intense buffy fulvous ; pectoral collar and flanks gray, the gray of flanks 

 encroaching on belly ; top of fore legs grizzled buffy fulvous ; wrists and 

 fore feet dirty yellowish white ; hind feet white. 



Remarks. The latter part of September, 1900, John Muir and I, after 

 ascending Bloody Canyon to Mono Pass, came upon one of these large 

 hares among the Murray and white bark pines on the west side about two 

 miles below the Pass, and near Dana Creek, which is one of the heads of 

 Tuolumne River. The Paiute Indians at Mono Lake showed me a number 

 of snow-white winter skins of this rabbit, and told me that in winter it 

 comes out of the mountains and inhabits the higher sage-brush slopes on 

 upper Rush Creek, from which locality the Biological Survey has recently 

 secured specimens, through the courtesy of Will ,T. Farrington, of Mono 

 Lake. All of these specimens unfortunately are in the white winter pelage, 

 though most of them show some dark gray on the head and some pale 

 fulvous on the ears, nose, and fore feet. The ears are strongly washed 

 with pale fulvous. The ear-tips are black on both sides, but the black area 

 is not so large as in the specimen in summer pelage from Hope Valley. 

 In typical campestris also the black ear-tips are smaller in winter than in 

 summer. 



Measurements. Type specimen: Total length, 635; tail vertebrae, 112 ; 

 hind foot, 167.
