1 Type. 



Subfamily PLECOTIN^. 



This subfamily is represented in North America by two genera, Cory- 

 norhiims and Eiiderma which may be recognized among the other 

 VespertlUonidw of the region by their huge ears, joined together across 

 the forehead. None of the North American Yespertilioninw show this 

 peculiarity. 



Genus EUDERMA H. Allen.

 Generic characters. — Deutal formula : 5 c, ^.-^^ ',P'iii, J-^; — =31.

Ears (PI. 1, lig. 11) even larger than in Cori/norhiuus, joined together 



across forehead and with posterior base of tragus united with external 



basal lobe. Face without evident glandular swellings. 



Remarlis. — The genus Euderma resembles Gorynorhinus more closely 



than any other American bat, but differs in the presence of two less 



premolars, in the simple nostrils, and in the more complicated structure 



of the ear. Only one species is known. 



EUDERMA MACULATUM (J. A. Allen).
