OCHOTONA PRINCEPS BRUNNESCENS HOWELL 



BROWN CONY; CASCADE CONY 



Ochotona fenisex brunnescens Howell, Biol. Soc. Wash. Proc. 32 : 108, 1919. 



Type. Collected a,t Keechelus, Wash., by George G. Cantwell, August 23, 

 1917. 



General characters. Slightly larger than the other Oregon forms, rather 

 uniformly brownish. Summer fur, whole upper parts, except ears, uniform cin- 

 namon brown, slightly darkened over back by black-tipped hairs ; ears blackish, 

 margined with white; belly buffy; throat clear cinnamon. Half -grown young 

 very similar to adults in coloration. 



Measurements. Total length, 205 mm; hind foot, 34; ear (dry), from notch 

 20. Weight : Two males, 143 and 152 g ; of 2 females 153 and 170 g, respectively, 

 (Dice, 1926, p. 3). 



Distribution and habitat. Extending from British Columbia 

 down through the Cascades of Waslri n gt on 5 these brown conies 

 occur on Mount Hood, and in the high part of the range on Mount 

 Thielsen at Crater Lake and Anna Creek, and on and around Mount 

 McLoughlin, mainly above the black lava flows of the lower levels 

 (fig. 18). Generally the rock slides in which they live are of the 

 dark-gray basalts, more or less covered with lichens and mosses, 

 with which their colors harmonize perfectly. 



General habits. Like other species of the group, the brown conies 

 live in the cavities of deep masses of broken rocks, the talus from 

 cliffs and peaks, or the slide rock on steep slopes, where they feed 

 and play and squeak in summer, stack their hay under the rocks in 

 autumn, and live buried under deep snow in winter. In the spring 

 only the sticks and hard parts of their haystacks remain under the 

 rocks with handfuls of little dry, hard, shotlike pellets to mark their 

 feeding and sitting places and runs. In summer their interesting 

 ways are readily observed by all who visit the mountains, but little 

 is known of their winter life deep under the snow and rocks. 



OCHOTONA FENISEX FUMOSA HOWELL 

 DUSKY CONY 



Ochotona fenise fumosa Howell, Biol. Soc. Wash. Proc. 32: 109, 1919. 



Type. Collected at Permilia Lake, west base of Mount Jefferson, Oreg., by 

 J. Alden Loring, October 4, 1897. 



General characters. Medium size, and very dark. Whole upper parts dark 

 grayish brown, much darkened over the back by black-tipped hairs, sides more 

 brownish ; ears dusky with buffy margins ; lower parts and feet buffy or brown- 

 ish gray ; soles of hind feet dusky ; darkest in fresh fall pelage. Young similar 

 to adults. 



Measurements. Total length, 200 mm; hind foot, 32; ear (dry), from notch, 

 19. 



Distribution and habitat. This very dark-colored cony is merely 

 a local color-form inhabiting the fresh, dark lava flows of the 1 lower 

 slopes of the Cascade Range south of Mount Hood. There are 

 specimens from the west slope of Mount Jefferson, the Clackamas 

 River, 15 miles above Estacada, a few miles above McKenzie Bridge, 

 and around the base of the Three Sisters Peaks. Those reported by 

 Stanley G. Jewett and R. Bruce Horsfall from near Multnomah
