There is a thick glandular fold (fig. 27) arising from the muz- 

 zle just exterior to each nostril and projecting upward and inward 

 so that the tips of the two touch. The ears are extraordinarily 

 large for the size of the animal, almost equalling the body in length. 

 The basal part of the anterior edges of the two are joined together 

 across the forehead, the basal part, up to the point of union, being 

 much thickened. The anterior edge is convex for its entire length; 

 the posterior edge convex basally, with a slight notch just below 

 the tip. General form of the ear, hastate. The tragus is long and 

 gradually tapering to the narrowly rcmnded tip. 



The membranes are thin and delicate, about the color of the 

 basal ])art of the fur on the back. Fingers and fore arm the color 

 of the surrounding membranes.
