Uroderma bilobatum, distinct in fresh specimens and fading in dry- 

 skins, might be mentioned. The species ranges from southern Brazil 

 north at least to Costa Rica.

In the forest near Gatun Uroderma bilobatum was located several 

 times, a few in a place, clinging during the day in clusters to the 

 midribs on the under sides of large palm leaves. They usually 

 choose darkened spots where the leaf was folded over, or overhang-

Andersen (1908, p. 220) in a revision of the genus places Uroderma 

 convexum Lyon in synonymy. Comparisons made by me seem to 

 justify this disposition of the name. Andersen records Panama 

 specimens from Colon, Brava Island, Cebaco Island, Jicaron Island, 

 Insolita Island, and Gobernador Island. With the exception of Colon 

 the same localities for specimens in the British Museum had been 

 listed by Thomas (1903a, p. 40), who also questioned the validity of 

 Uroderma convexum Lyon. 



A specimen erroneously referred by Bangs (1901, p. 644) to 

 Vampyrops helleri was collected by W. W. Brown, Jr., on San Miguel 

 Island. The same mistake in identification applies to specimens 

 recorded by Bangs (1902, p. 50) from Bugaba, and by Allen (1904, 

 p. 79) from Boqueron. 



Anthony (1916, p. 373) records examples from Capeti, Chepigana 

 and Real de Santa Maria. 



Specimens examined : Boqueron, 6 1 ; Bugaba, 6 2 ; Capeti, 7 1 ; 

 Chepigana, 1 1 ; Chorrera, 4 1 ; Puente de Pifia (near Bocas del Toro),

Genus VAMPYROPS Peters 



The approach in outward appearance of Vampyrops to Uroderma 

 has been referred to in the treatment of that genus. Vampyrops is, 

 however, easily separable from Uroderma by the densely furred
