 braincase greatly deepened, its floor so elevated that lower rim of 

 foramen magnum is above level of rostrum ; teeth essentially as in 

 Ohilonycteris, except that lower incisors are of about equal size and 

 uniform structure, the inner tooth lacking all trace of backward 

 extension of the crown; dermal outgrowths on chin very highly 

 developed.
