VESPERTILIO TEMMINCKII. 
Ears large, auricle very broad at the base, with the posterior lot* descending, ami terminating with a rounded 
proeess opposite to the angle of the mouth ; the anterior and posterior lobes meet when the ears are in a collapsed 
state, and constitute a deep fold including a long linear- lanceolate tragus. The rostrum is very short, depressed, 
and obtuse, and the skull globular, and distended between the ears- The entire length is three inches, of which 
nearly one half is made up by the tail. The distinguishing character of this species is a very long, delicate,, soft silky 
fur, grayish brown above, and brown, with a tawny tint, underneath. The interfemoral membrane, and the membrane 
of the anterior extremities near the body and thighs, are marked with regularly parallel transverse veins.
