Mice of this subspecies were recorded from the lower chaparral
association below about 4000 feet elevation along the coastal face of
the San Gabriel Range. They were trapped on greasewood-covered slopes,
in mixed growths of white sage and buckwheat, and beneath scrub oak
and lilac chaparral; however none was taken in the heavy chaparral of
the upper parts of the chaparral association.
One small juvenile in gray pelage was taken in San Antonio Canyon on
October 1, 1951.
