 widely separated from each other and from canine. Lower incisors

Crown elevated above forehead; muzzle lengthened; lower lip 

 broad; surface of ear conch covered with papillae, the outer margin 

 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 

 from the outer pair; first premolar equal to or larger than the second. 



*The derivation of this word is not given, and Natalus does not appear in 

 the dictionary. Natalis is a Roman surname ; Natalis, adj., natal, or belong- 

 ing to birth, may have been intended. Natalus is probably a misprint.
