Urocyon californicus (Mearns). California Gray Fox. 
Fox tracks were noted abundantly along the upper Santa Ana 
chiefly in the Upper Sonoran zone. We secured an adult male 
specimen July 8, 1905, a mile or so above Seven Oaks (about 
5100 feet altitude). A male specimen was trapped at the edge 
of the big cienaga at Bluff lake, 7500 feet altitude, July 20. This 
is high Transition, and signs of foxes were scaree. A third 
example, also an adult male, was trapped at Cactus Flat in the 
pinyon belt on the desert slope of the mountains, August 17. 
All three of these specimens are in worn and faded summer 
pelage. They measure as follows, in the order given above:

Mephitis occidentalis holzneri Mearns. 
Southern California Skunk. 
Striped skunks were in evidence along the upper Santa Ana 
from Seven Oaks, where an immature female was trapped July 
11, 1905, to Fish ereek, 6500 feet altitude. A young female was 
taken near our camp at the latter place July 5; this, or another 
individual was seen previously about a large prostrate hollow 
log. A female specimen was captured at Bear lake, August 2. 
The little spotted skunk (Spilogale) ought to oceur in the 
foothill portion of the region under consideration, but we failed 
to obtain evidence of its presence. 
Sorex ornatus Merriam. Adorned Shrew. 
Shrews may oceur along most of the permanent streams of 
the San Bernardino mountains, and I do not doubt that diligent 
and prolonged trapping would result in their discovery very gen- 
erally in favorable places. But in all our trapping we succeeded 
in securing shrews only in the vicinity of Bluff lake, 7500 feet
