Color. "Skin of face round eyes bluish gray, lips and chin pinkish 

 gray." (Pocock). No signs of these colors on the type, the face being 

 black where bare. Nose black, cheeks speckled black and yellow ; black 

 band across forehead extending across sides of head over ears and 

 meeting at back of crown ; crown speckled black and yellow : back of 

 head and hind neck, and space between shoulders speckled with black 

 and yellowish white; dorsal region to tail, and flanks speckled black 

 and ochraceous buff ; long hairs of whiskers extending back of ears, 

 sides of neck, and throat white ; shoulders and arms on outer side to 

 elbows black speckled with white, forearms black ; outer side of thighs 

 gray, speckled with black and ochraceous buff like back; legs below

Measurements. Total length, 725 ; tail, 345 ; foot, 100. No skull. 



The type is a young animal with a black nose, but some adults 

 have a white nose patch. This species is not nearly allied to L. 

 PETAURiSTA as somc writers have believed, the only similarity in color- 

 ing between them being the black frontal band going around the head. 

 It is nearer in coloring, so far as the dorsal region is concerned, to L. 



FANTIENSIS.
