Myotis nigricans (Wiep). 
One Q, Bogaba, July 1. 
Eptesicus fuscus miradorensis (H. Aten). 
One @, Boquete, 4,800 feet, March 23. 
Lasiurus borealis mexicanus (Saussure). 
One ¢, Boquete, 4,000 feet, February 18. 
Rhogeessa tumida H. Aten? 
One @, Bogaba, July 6. Mr. Miller, to whom I submitted this specimen, is 
a little donbtful as to its identity with R. tumida, but on the strength of a 
single specimen preferred to so determine it. 
Hemiderma brevicaudum (Web). 
Thirteen specimens, Bogaba, July. This series presents a wide range in 
the color of the upper parts, varying from hair-brown to russet, with every 
intermediate shade. 
Glossophaga soricina (PAa..as). 
One 9, Bogaba, July 2. 
Artibeus intermedius J. A. ALLEN. 
Three specimens, an old 9, and youngish @ and 9, Bogaba, July. The 
younger specimens are more sooty, with the facial stripes less well indicated 
and have smaller skulls, and thus agree with the young described by Dr. Allen. 
I must confess, however, that I was at first inclined to regard these as belong- 
ing to a different species from the old one. The difference in size is great and 
the skulls do not show the degree of immaturity that one would expect with 
the difference in size. 
Vampyrops helleri Peters. 
Six specimens, Bogaba, July.
