1908] Grinnell_—Biota of the San Bernardino Mountains. 19 
list nearly everything of the region. Green-tailed and spurred 
towhees, mountain quail, Cassin purple finches, linnets, and blue- 
fronted jays were among those of conspicuous abundance. In 
the black oak and fir belts Eutamias speciosus and Callospermo- 
philus were abundant; and in the pinon and service-berry, 
Eutamias merriami. Out on the sage flat Ammospermophilus 
leucurus and Perodipus agilis formed a curious association of 
mammals and both at a very high altitude. 
DOBLE. 
Doble is a deserted mining town just east of Gold mountain 
and north of Baldwin lake. It is about 6900 feet in altitude, in the 
sage and pinon Upper Sonoran zone. The antelope chipmunk, 
Merriam kangaroo rat, and desert jackrabbit show the desert 
nature of the mammal fauna. Among birds, two species were 
more abundant in this vicinity than anywhere else we went, the 
pinon jay and Brewer sparrow. Rock wrens, Say phoebes, Cali- 
fornia sage sparrows, mourning doves, mountain bluebirds, and 
linnets were also conspicuous members of its fauna. The region 
is extremely arid, and the few drinking places, water piped from 
wells, were the points where the birds of the region were sure to 
be seen, if hard to find elsewhere. 
SARAGOSSA SPRINGS. 
Saragossa springs is at an elevation of 7500 feet on the south- 
west side of Gold mountain. The watershed there is entirely 
towards the desert, and the region is very arid. It is about on 
the boundary between Upper Sonoran and Lower Transition. 
There is a mixture of Jeffrey pine, western juniper, and moun- 
tain mahogany, with plenty of sage; while on the south sides of 
the surrounding low ridges the pinon prevails. Desert jack- 
rabbits and Merriam chipmunks, pigmy nuthatches, western 
chipping sparrows, Cassin purple finches, Sierra juncos, and 
Brewer sparrows were some of the most abundant animals ob- 
served.
