Las Animas Chipmunk 
175 
blackish, pale chestnut or rufous bordered; inner pair of dark 
stripes rather pale chestnut rufous, darkest posteriorly, with a 
little blackish; outer pair a pale shade of the same, not very distinct 
from the color of the sides, which are pale yellowish rufous; post- 
auricular spot large and whitish; top of head and shoulders quite 
gray; dark facial stripes narrow and blackish, not clearly black; 
flanks grayish; upper surface of tail with less black and more 
rusty than in typical qiiadrivittatus ; under surface of tail pale 
bright rufous, not the dark chestnut of quadrivittatus . 
There are no cranial characters by which it may be distinguished 
from qiiadrivittatus. 
Distribution. — At present this form is known only from the 
type locality, and from Gaume's Ranch, in the northeast comer of 
Baca County. Presumably it inhabits the region known locally 
as "The Cedars," a sandstone mesa country in the eastern part 
of Las Animas County, and the western edge of Baca County. 
This district is cut up into many shallow canons and gulches, 
with rather an abundant growth of cedars {Sabina scopulorum), 
and some pinons. It is a very arid region, which fact most likely 
accounts for the pale colors of this animal.
