of the type: Head and body, 185 mm.; tail, 150; hind foot, 40; condylo- 

 basal length, 45; zygomatic width, 23.5; width of brain case, 19; 

 maxillary tooth row, 17. 



Specimen examined. — One, the type. 



Remarks. — -The three forms just enumerated, Tupaia glis pulonis, 

 T. g. sordida, and T. g. pemangilis, are very closely related to one an- 

 other. These three insular forms are not based on large series and it 

 does not appear improbable that larger numbers might even show that 

 but a single form inliabited the three geographically associated 

 islands of Tioman, Pemangil, and Aor, as the differences separating 

 the three are not greater than are often found in the same form 

 having a greater area of distribution.

Type-locality. — Sinkep Island, Rhio-Linga Archipelago. 



Type-specimen. — In United States National Museum, Cat. No. 

 113148, skin and skull, adult male, Sinkep Island, September 4, 1901; 

 collected by Dr. W. L. Abbott; original number, 1275; in good condi- 

 tion. 



Geographic distribution. — Sinkep Island. See No. 19 on map on 

 page 75. 



Diagnosis. — Related to Tupaia glis ferruginea, but rather dark and 

 reddish, and with the tail not essentially different in color from rest 

 of the animal. Mammse, 2-2=4. 



Color. — Tupaia phxura differs in color from T. glis ferruginea in 

 having less black mixed in with the ferruginous-chestnut in the region 

 of the neck and shoulders and more black and less grizzling on the 

 lower back and rump. The tail both above and below is a coarse 

 grizzle of black and tawny ochraceous, the black predominating on 

 the upper surface and the tawny ochraceous slightly in excess in the 

 middle line below. Wlien viewed from above the tail is concolor 

 with the rest of the upper parts. The under parts, legs, feet, shoulder 

 stripe, etc., do not differ in color from the corresponding parts of 

 T. glis ferruginea. 



Skull and teeth. — There are -no characters by which the skulls and 

 teeth of Tupaia phseura can be distinguished from those of T. glis 

 erruginea. (Plate 9, fig. 7.) 



Measurements. — Tjrpe: Head and body, 195 mm.; tail, 140; Iiind 

 foot, 44; condylobasal length, 47.5; zygomatic width, 26.5; width of 

 brain case, 19.5; maxillary tooth row, 19. For measurements of 2 

 other specimens see table, page 51. 



Remarks. — Tupaia phseura is a very strongly characterized geo- 

 graphic form of T. glis and has no close relatives. It is at once dis-
