Co., Calif.
Dec. 27, 1932
number of seemingly used entrances in one group was
6, altho the number of old broken down entrance
in such a group would greatly add to the number.
Solitary holes, however, were commoner. Most
of the entrances had either a small pile of
earth outside or nothing. In no case was there
ever more earth than would be needed to cover
the palm of one's hand. The diameters of 13 ap-
parently used holes are as follows in mm.:
43-45-47-44-45-47-49-49-51-57-62-49-50. The
hole were mostly circular altho some were [illegible]
squareish. Most of them went into the earth
at an angle of from 25° to 45° to the surface.
Signs of Thomomys bottae were numerous here-
abouts. Many small holes also present were
probably occupied by Peromyscus truei and
P. maniculatus .
At 11 a.m. in the area in which I was studying
Kangaroo Rats a cottontail jumped up from
a form in a clump of Bromus rubens and
Allium at the base of a small dead tree.
It was about 25 feet away when it hopped
up and ran away 10 feet in some tall
glass and remained perfectly genet at attention.
In the sunlight and dry grass out in the
open it seemed very gray. Shot the animal.
There was no fresh of any sort for 50 yards in
