Under fur dark broccoli-brown, the shorter hairs tipped with dull, 

 light cream-buff, the longer with black, and all showing a distinct 

 gloss in certain lights. The general effect is darker and less yellow 

 Ihan in Arctogalidia inornata. A distinct trace of the median 

 dorsal line extends from shoulders to lumbar region, but the lateral 

 lines are absent. Head, ears, feet, lower portion of front legs and 

 distal half of tail blackish, the forehead, crown and cheeks finely 

 and inconspicuously grizzled with gray. Basal half of tail like 

 back, but slightly darker. Under parts dirty gray, slightly but 

 distinctly tinged with yellow, particularly on throat and imder 

 surface of neck. Sides of neck buff (a litlle less yellow than that 

 of Ridgway), forming a rather conspicuous contrast with sur- 

 rounding parts. 



Skull and Teeth. — The skull and teeth are essentially as in 

 Arctogalidia inornata, but the premolars appear to be more robust. 



Measurements. — External measurements of type: Total length, 

 1,050; head and body, 515; tail, 535; hind fool, 81 (77). 



Cranial measurements of type : Greatest length, 106 ; basal 

 length, 98; basilar length, 94; median palatal length, 56; breadth 

 of palate between anterior molars, 14.6; zygomatic breadth, 58; 

 constriction in front of postorbital processes, 17 ; constriction behind 

 postorbital processes, 14; mandible, 78 ; maxillary toothrow (ex- 

 clusive of incisors), 37; mandibular toothrow (exclusive of in- 

 cisors), 41. 



Specimens E.vamined. — Two, the type from Linga Island and an 

 immature male from Sinkep. 



Remarks. — By its small size and obsolete dorsal markings this 

 species is readily distinguishable from Arctogalidia leucotis and A. 

 stigmatica. Its relaiionship with the small A. inornata of Bunguran 

 Island is much more close; but the two small species differ very 

 considerably in general coloration.
