Characters. — Closely related to ITippoHideros hicolor and //. fulvus^ 
with which it agrees in all general external features. Size much less 
than that of //. fulva and slightly greater than in //. hicolor. Termi- 
nal erect portion of noseleaf broader than in //. hicolor; skull more 
inflated in front of orbits, and with broader palate and interpter\^goid 
region. 
Noseleaf. — The noseleaf is slightly larger than that of IUpposideros 
hicolor., but not essentially difi'erent in form. The posterior erect 
portion is slightly broader, but the difference may be in part sexual, 
as the only specimen of //. hicolor at hand is a female. 
Color. — Two distinct color phases occur. In the dark phase, repre- 
sented ])\ the typo, the hairs of the back are seal brown through 
terminal third, light smoke gray basally in strong contrast. On under- 
parts the fur is broccoli brown throughout, the hairs slightly darker 
at tip. In the light phase the whole body is mars brown, the hairs 
everywhere light gray at base, but this feature most noticeable on 
back. Ears and membranes blackish. This description is based on 
specimens that have been immersed in alcohol for about six months. 
Skull and teeth. — The skull is so mucli smaller than that of Hippo- 
sideros fidvus that it needs no special comparison. From the skull of 
IL hicolor it differs in slightly larger size and in several details of 
structure. The width of the constricted portion of the palate is con-
