_Specimens examined._--Total, 2: [Male], MV 7872/507, prepared
by D. Watson, killed by a car "near" the Park Well on September 24,
1937; [Female] (an unnumbered cased skin only), found dead
"near" the Park Well on June 21, 1937.
Since 1934 these squirrels have been observed and recorded each year
except in 1938, 1943, 1947, 1953, 1957, and 1958. The 77 reported
observations can be grouped as follows: 11 from within a mile of the
entrance to the Park, 14 from the North Rim or higher parts of canyons
adjacent to it, 38 from Chapin Mesa south of Far View, and 14 not
classifiable. The large number of observations on Chapin Mesa, chiefly
in the vicinity of Park Headquarters, indicates the presence of more
observers rather than more squirrels in this area.
