SOME NOTES CONCERNING THE PALLID BAT 
Atrozous pallidus pacificus Merriam. 
The Pallid Bat ranges more or less throughout the Austral 
Zones west of the Rocky Mountains, as far as Lower California. 
In color these bats are a yellowish drab, under parts clear and 
unmixed, with darker back, but irregularly shaded by the dusky tips 
of the hairs. 
They are fairly large in size, and have a body length of about 
one hundred and twenty millimeters, the length of the forearm being 
about fifty-four millimeters. The ears, when bent over the nose, 
measure about twenty millimeters beyond the tip. The teeth are very 
strong and can give a pretty good bite when the bat is molested. 
These measurements, of course, vary according to the size of the 
bats. 
In Sierra Madre during the day the favorite hiding places of 
these bats are in dark cracks or crevices, such as those between the 
walls of houses, in attics or in old barns. 
The first colony I found in the month of May. These bats had 
selected a narrow tunnel-like space between the ends of the roofing 
and the box-like gable facings of an old barn. They had evidently 
lived in this place for years, for the droppings were very thick in 
the lower ends of the gables. 
For the entrance to the tunnel-like space the bats crawled through 
a hole at the apex of the gable, this giving them access to both sides. 
To reach the bats, I went up to the loft and poked in between the 
roofing boards with a stick. In a few minutes the bats began to 
emerge above me. Some flew back and forth, while others crawled 
in the spaces at the other end of the barn. 
The boy with me armed himself with a stick, and, when they 
came near him, knocked the bats to the floor. From the blow of the
