eral color of this Bat is pale sepia brown, or yellowish brown, the fur 
darker at the base; the belly is 
“ggrayish white. The tail does not 
extend beyond the interfemoral 
membrane. Total length, about 
4 in. (105 mm.); tail vertebre, 
about 2 in. (50 mm.); forearm, 
about 1.60 in. (41 mm.); ear, about 
1.20 in. (30 mm.). 
The range of the Big-eared Bat 
is restricted, so far as known, to 
southeastern United States, the type locality being Georgia. 
Big-eared Bat. 
Family MOLOSSIDA. 
Nyctinomus depressus (WarRD),* FREE-TAILED Bat. It is not 
unlikely that stragglers belonging to this species may occur in Illinois; 
’ . a specimen was found dead in Central 
Park, Cedar Rapids, Iowa, in the fall 
of 1g10, which was secured by Dr. 
B. H. Bailey who kindly sent it to me 
for examination. It may readily be dis- 
tinguished from others of our Bats by 
the character of the tail, the free por- 
tion of which extends about an inch 
beyond the interfemoral membrane. 
Other characters which will aid in its 
identification are, ears large and ap- 
parently united; general color very dark umber brown. Measurements 
(from dried skin), total length, about 4.50 in. (115 mm.); total length 
of tail vertebree, about 1.65 in. (42 mm.); length of free portion of tail 
vertebre, about .go in. (23 mm.); length of forearm, 2.40 in. (61 mm.); 
height of ear about .65 in. (16.5 mm.) The occurrence of this Bat 
in eastern Iowa greatly extends its previously known range. Speci- 
mens of this wandering Mexican species have been taken in California, 
Arizona, Colorado and Nevada.t Another and quite different species 
belonging to this genus (NV yctinomus mexicanus) is common in Florida 
and the Gulf states.

tMr. Gerrit S. Miller, Jr. considers the specimen taken in Nevada and described 
by H. Allen as Nyctinomus macrotis nevadensis (Monog. Bats N. Amer., 1893, p. 171) 
to be this species. (See Proc. Biol. Soc. Wash., XV, 1902, p. 250.)
