BATS. 
CHIROPTERA. 
SAY’S BAT. 
Myotis subulatus (Say). 
?Vespertilio subulatus Say, Long’s Exped. Rocky Mts., I]., 1823, p. 65. 
This species has a general distribution throughout North America 
east of the Rocky Mountains. 
Dental formula: 2, 7/,:-0,7/)5 Pit. /s3 Wt, la: 
The length of Say’s bat is about like that of the little brown bat, 
3.15-3.55 in. (80-90 mm.), but the fore arm is usually a trifle 
shorter—about 1.4 in. (34-37 mm.). The ears 
(Fig. 5) are long, reaching beyond the nose when 
laid forward. The tragus is very slender, and 
gave the bat its specific name, subulatus meaning 
awl-shaped. 
The color resembles that of the little brown 
bat, both species varying considerably in depth 
of color. 
I have never taken this bat within the state, 
but in many localities it can not be uncommon. 
There is one specimen without data in our collec-  ya.P%né7 
tions, and one from East Cairo, Ky. It isapparently 
very unevenly distributed. By some reliable observers it is reported 
as being uncommon, while others in similar environment report it 
as very abundant. It hibernates, and has been found in winter in 
hollow trees in immense numbers. The young are produced in 
June. Twenty pregnant females examined by Dr. Burt G. Wilder, 
each contained two young, as did also each of ten examined by 
Dr. A. K. Fisher*. More than this have been reported in a litter, 
but two is the usual number.
