of the occasion to perform their devotions and although I was the only 
one that seemed to have any idea of desecration, I soon felt like retiring 
especially since at the last shot I noticed that even as I raised the 
gun a chola girl had slipped in front of me and as the report rang out she 
was devoutly kneeling in prayer almost under the muzzle of the gun. 
Hemiderma perspicillatum Linneus. Common HEMIDERMA. 
Fifty-three specimens: Balsas (1), Moyobamba (51), Tambo Yaku 
(1). 
This very common bat was particularly abundant in the vicinity of 
Moyobamba and if desired it might have been obtained in much larger 
numbers. Its usual roosting place is under a thatched roof where it 
often collects in large numbers in company with Glossophaga. 
Vampyrops zarhinus H. Allen. 
A bat obtained near Yurimaguas is referred to this species since it 
is slightly larger than V. z. incarum. 
Artibeus planirostris fallax Peters. 
Seventeen specimens, Moyobamba. 
This series presumably represents the A. hercules of Rehn which 
Andersen has referred with a slight query to the synonymy of A. »p. 
fallax.* It might now be possible to dispose of this name still more 
definitely if satisfactory material representing typical fallax were at 
hand. As compared with two specimens from Cayenne (Uroderma 
validum of Elliot), the Peruvian bats are slightly larger and decidedly — 
less brownish in color. The skulls measure slightly more than the aver- 
age given by Andersen but fall a trifle short of his maximum. A larger 
series of fallax would probably show enough variation to cover such 
differences. 
This large Artibeus was fairly common at Moyobamba where it was 
found roosting in mango trees under the protection of their thick heavy 
foliage. 
Desmodus rotundus (Geoff.). VAMPIRE. 
Forty-three specimens: Hacienda Llagueda (35), Cajamarca (7), 
Moyobamba (1). 
Blood sucking bats are abundant throughout the greater part of the
