widely separated from each other and from canine. Lower incisors 
six, small; anterior premolars in both jaws large, laterally compressed, 
and with well-developed cutting edges; maxillary molars with inner

Crown elevated above forehead; muzzle lengthened; lower lip

ending between tragus and angle of mouth; thumb nearly hidden in 
antebrachial membrane; wing membranes from lower end of tibia; 
wing and interfemoral membranes with dotted lines over them; tail 
long, inclosed in interfemoral membrane; inner upper incisors diverge

*The derivation of this word is not given, and Natalus does not appear in 
the dictionary. WNatalis is a Roman surname; Natalis, adj., natal, or belong- 
ing to birth, may have been intended. Natalus is probably a misprint.
