base, and with small postauricular patches of much lighter colored hair which 
are the same color as the underparts; below, everywhere light buff of Ridgway, 
the hairs darker at the base. Ears and membranes black. 
Ears . — Very large and broad; connected by a very low ridge, scarcely discern- 
able on the crown ; inner margin well rounded at base but not conspicuously so ; 
outer margin evenly convex from tip to base; tragus very tail, simple. Ears 
crossed by a number of transverse folds which appear as fine lines, seven visible 
on the upper and eight on the lower side. 
Skull . — Normal for the genus. 
Measurements . — (compared with those of velatus, in parentheses) : Total length, 
108 mm. (112); tail vertebrae, 52 (55); height of ear from base of tragus (dried 
skin), 26.7 (24.3, macrotus, 26.3); greatest breadth of ear, 17.7 (19.4, macrotus, 
19.1); length of forearm, 48.3 (46.8, macrotus, 48.3). 
Inamharus most closely resembles macrotus from which it may be 
readily distinguished, however, by its lighter color and differently 
shaped ear. The ear of macrotus has a wide and abrupt expansion at 
the base on the inner margin, in this respect only exceeded in the genus 
by velatus. The ear of inamharus, however, is more evenly rounded 
at the base of the inner margin and is somewhat narrower, especially 
at the base, than in macrotus. Also the ear of the new species is very 
black, contrasting with the yellowish color of the ear in the only adult 
specimen of macrotus available for comparison. As this specimen of 
macrotus is an alcoholic perhaps too much stress had best not be made 
on this point. 
Inamharus differs even more apparently from velatus and montanus 
in coloration and ear characters than it does from macrotus.
