present, with no great accession of new material, to use this name. 
But after noting the faint-hearted and apologetic way in which the 
monographer has given it place,* and after the comparison of our 
Venezuelan specimen with a single Brazilian one and finding the teeth 
of the latter actually the smaller, one is strongly tempted to discard 
palmarum in favor of lituratus. 
Uroderma bilobatum Peters. Common Uroderma. 
Two specimens (skins), Encontrados, Sept. 25, 1910; collected by 
H. F. Raven. 
Vampyrus spectrum (Linnzus). False Vampire. 
One specimen (skin), Encontrados, Sept. 30, 1910; collected by H. 
F. Raven. 
Saccopteryx leptura (Schreber). Striped Sac-winged Bat. 
Three specimens (skins), El Panorama, Rio Aurare, Jan. 18-21, 1911. 
Two were obtained from their diurnal resting place in a decayed 
crevice in the side of a tree and the third was shot while flying back 
and forth over a trail bordered on either side by tall trees. Others, 
apparently of the same species, were seen. 
The palest specimen agrees well with the description of S. canescens 
except for the slight development of the light superciliary stripe. The 
head and under parts are pale Isabella color, the back more brownish, 
and the marginal hairiness on the membranes slightly rusty. The 
darkest one is chiefly Vandyke brown, becoming seal brown between 
the light stripes. The third is intermediate between the other two, 
thus forcing the conclusion that color is of relatively little importance. 
Rhogeésa io Thomas. South American Rhogeésa. 
One specimen (skin), El Panorama, Rio Aurare, Jan. 24; two speci- 
mens (in alcohol), ro miles north of Cucuta, March 16; seven specimens, 
Empalado Savannas, April. 
The color of the body and head of the dry specimen evidently is 
even brighter than that of the type as described by Thomas. Both 
upper and under parts are bright clay color (Ridgw., Pl. V, No. 8), 
the head and shoulders being somewhat lighter than the back and rump 
*In one place (p. 278), he says,-—‘'I should not have tried to keep this form separate from A. 
j. lituratus, if the name palmarum had not been available,"’ thus confessing a prostitution of zoology 
to nomenclature which scarcely seems justifiable,
