1908] Grinnell—Biota of the San Bernardino Mountains. 157 
altitude. In several other likely places, such as the extensive 
Boreal meadows at the head of the south fork of the Santa Ana, 
we tried every sort of bait we could think of—earthworms, meat, 
bird brains—but to no avail. And the shrews we did get finally 
were caught in traps baited with rolled oats. In two cienagas 
near Bluff lake, the latter part of July and the first of September, 
1905, we were trapping assiduously for meadow mice. The open 
runways of these animals through the grass and beneath the rank 
Veratrum herbage were plentiful, and in these we placed our little

“‘oee-whiz’’ and ‘‘sure-catch’’? mouse traps, baited mostly with 
rolled oats. July 18 a female shrew was caught; three males on 
July 20; and September 2, a male. In all but the last case the 
shrews were found in the traps at noon (the traps having been 
visited in the morning), or before dark in the evening. Only the 
September victim was found in the morning. It would seem from 
this that these little animals do a great deal of their foraging in 
the daytime. They got into our traps hardly for the sake of bait, 
but because the traps were set in roads the shrews were in the 
habit of following. 
I fail to see any difference between these San Bernardino 
mountain specimens and some from Mt. Pinos, the type locality 
of ornatus.

The characteristic workings of this animal were seen plenti- 
fully over most of the Pacifie slope of the San Bernardino moun- 
tains. They were particularly numerous on canon bottoms and 
at the margins of cienagas, but were also often seen high on the 
dryest mountain sides. I saw a much-branching system of mole- 
ridges, presumably belonging to this species, along a little stream 
running into Dry lake from the eastward, 9100 feet altitude. 
Along the upper Santa Ana workings were plentiful, and many 
fresh ones would appear within an hour after each thunder- 
storm. I spent much time in trying to dig the animals out, in
