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 Linnaeus. COMMON HEMIDERMA. 



Fifty-three specimens: Balsas (i), Moyobamba (51), Tambo Yaku 



(i). 



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 (i). 



Blood sucking bats are abundant throughout the greater part of the
