158 PROCEEDINGS OF THE ACADEMY OF [March, 



Characters. — Like Tupaia ferruginea from Singapore, but with 

 much darker tail, its upjier and lower sides concolor with corre- 

 sponding surfaces of body. 



Color. — Dorsal surface of head, body and tail a fine grizzle of 

 seal-brown and dark ferruginous, the ferruginous in excess on 

 head, shoulders and anterior portion of back, the seal-brown in 

 excess on tail and posterior half of back. The color is most dark 

 on rump, lumbar region, flanks and basal third of tail. Chest, 

 throat, chin, cheeks, muzzle, sides of neck and front legs olive-buff, 

 rather darker than that of Eidgway, brightest along middle of 

 throat. On the thinly haired posterior half of the ventral surface 

 the olive disappears, leaving a didl tawuy, Avhich extends over 

 inner surface of hind legs, and, somewhat brightened, forms the 

 light element of the grizzle of imder side of tail, where it is dis- 

 tinctly in excess of the seal-brown. Feet dusky bi'own. 



Skull and Teeth. — The skull and teeth do not differ appreciably 

 from those of Tupaia ferruginea. 



MeasuremenU. — Extei'nal measui'emeuts of type: Total length, 

 335; head and body, 195; tail vertebne, 140; hind foot, 46 

 (43.6). Two adult females from the type locality (Nos. 113,147 

 and 113,149) measure respectively: Total length, 325 and 335; 

 head and body, 185 and 195; tail vertebrae, 140 and 140; liiud 

 foot, 43 (40) and 44 (41). 



Specimens Examined. — Three, all from the type locality. 



Remarks. — Tupaia phwur a is closely related to true T. ferruginea 

 the type locality of which may be assumed to be Singapore, though 

 easily recognizable by its much darker tail. 



Macacus "cynomolgus" Autt. 



This monkey was common on the banks of the Indragiri river, 

 Sumatra. An adult male taken on September 21, 1901, does not 

 differ appreciably from specimens from the Malay Peninsula. 



Semnopithecus maurus (Schreber). 



Two were shot from a drove of twenty or more in a sago planta- 

 tion on Linga Island, August 25, 1901. Along the banks of the 

 Indragiri river the animal was plentiful. Four specimens were 

 secured. In the Linga skins the gray tips of the hairs on back 

 and shoulders are less conspicuous than in those fron^. the Indragiri 

 river.
