Ears separate, ear-conch very narrow and attenuated above, with 

 a rounded very distinct antitragus ; tragus much longer than broad, 

 rounded off above, slightly inclined inwards ; upper extremity of the 

 muzzle very much pointed and produced beyond the lower lip, nos- 

 trils opening by horizontal oval apertures ; no sac in the antebrachial 

 membrane ; wings from the ankles ; calcaneum considerably longer 

 than the tibia ; premaxillary bones much expanded at their bases ; 

 facial bones mesially concave ; anterior margin of the orbit in the 

 same vertical line with the first smaU premolar ; dental formula as 

 in Saccopteryx. 



Range. Neotropical Region (Mexican and Brazilian Subregions). 



This genus, which is represented by a single species only, appears 

 to connect the group Emballonurw with the group Noctiliones, re- 

 sembling the genus Noctilio very closely in the form of the ear- 

 conch, of the nasal apertures, and of the lower lip, and having 

 almost the same geographical range.
