 formed ; canines only moderately sharp in front ; pos- 

 terior root of zygoma not abnormally expanded; 

 typically no supplementary foramen on inner side of 

 bulla between carotid and foramen lacerum posticum. 

 Upper edge of rhinarium not produced, its anterior 

 surface convex, with normal nostrils and wide septum. 

 f Mastoid small, not bigger than paroccipital and 

 hardly surpassing auditory orifice ; carotid foramen 

 not behind middle of bulla; foramen ovale well 

 behind tip of bamular ; ridges of posterior palate 

 marginal. Claws short, sharp, much curved ; digits 

 webbed for two-thirds of their length. Snout not 

 produced; upper lip divided by wide philtrum. 



Bursa retained and marginal Bassaricyonince .

 which is above m' ; inferior edge of anterior nares

 much extended antero-posteriorly; a very distinct sup-

 lacerum posticum. Upper edge of rhinarium produced, 

 its anterior surface nearly flat, with vertically elongated 

 nostrils and narrow septum. Digits with powerful 

 claws, fully webbed. Anal glands a series of small
