shaped, pointed with flat outer base). Lower incisors missing. Caiiini simple, with a slight 

 cinguhmi. Premolars comparatively short and wide, compared to other Glossophaginae. 

 Upper molars without conceivable masticatory surface due to reduction of the commis- 

 surae. 



Anoura (figs. 39-41) 



A. caiidifer (fig.39): Skull: rostrmn not quite reaching half the total length of skull. Base 

 moderately vaulted, no angular deviation between palatinal and basal level (in German 

 literature: orthocran). Choanae at about the same level with Fossa glenoidalis (palate 

 comparatively long).

Upper incisors very small, the outer ones (dagger-shaped) twice the size of the iimer ones 

 (droplet- shaped), medially separated by wide gap (about four times the width of the 

 incisivi). Anterior premolar very small and caniniform, clearly visible distance to canine 

 tooth; also a diastema to the second premolar. Third upper premolar with tliree cusps, the 

 second one more or less forming a two-cusped transitional form. Molars flat, but all tliree 

 of them with fimctional masticatory surface (dilambdodont crown by top view). Row of 

 teeth in basal view ahnost rectangular; width over canine teeth only slightly narrower than 

 molar width of the palate. Lower mcisivi missing; Proc. coronoideus very flat.

A. cidtrata (fig. 40): Similar to A. caudifer, but differences in dentition: upper canines 

 strong with a sharp ridge mnning along tlie anterior edge; anterior lower premolar 

 enlarged to a long, narrow blade. 



A. geoffroyi (fig.41): Like A. caiidifer, but considerably larger; last upper premolar with a 

 median lingual cusp, projecting beyond the narrow base of the tooth.
