Noctilio albiventer Spix. Common NoctILio. 
One specimen, Yurimaguas. 
This is a dull brownish specimen with the under parts only slightly 
lighter-colored than the back. In size, it scarcely equals ordinary 
specimens of albiventer from Brazil and it is considerably smaller than 
the size given for N. zaparo, the type of which came from the Napo 
River in Ecuador not far north of Yurimaguas. 
Glossophaga soricina (Pallas). Common GLOSSOPHAGA. 
Sixteen specimens, all from Moyobamba. 
These were mostly brought to us by small boys who found them 
roosting under the thatch of the village houses. They are essentially 
like specimens from eastern Brazil.

p. 420, Dec. 31, 1913 — Type from Balsas, Peru. 
Twenty-nine specimens, Balsas. 
Although not seen elsewhere in western Peru, Glossophagas were 
found in great abundance at Balsas roosting under the roof of a church. 
The building was large and barnlike, simply constructed of rough 
- masonry walls and roofed with small poles which were overlaid with 
thatch. The interior formed a single rectangular room about 60 ft. 
long by 25 ft. wide with a raised altar at one end and a plain earth floor 
- extending thence to the door. There were no windows and when the 
large door was closed only a limited amount of light was admitted 
through the space between the eaves and the top of the walls. Some- 
what to my surprise, requests for the key to the church and permission 
to shoot in it in the absence of the priest were readily granted and about 
half the small population of Balsas accompanied us to watch the pro- 
ceedings. On opening the door, the light streamed in and the roof was 
seen to be literally covered with bats which immediately began squeak- 
ing and shifting their positions. At the first shot, a cloud of them flut- 
tered about the room a moment and then mostly settled again, only a 
few going outdoors under the eaves. After shooting into various parts 
of the roof and carefully scrutinizing the remainder, it was evident 
only one species was present. The total number, as estimated at the 
time, was not less than 2,000. A larger series of specimens might have 
been obtained, but some of the people that followed us took advantage
