attenuate rostrum. The suborbital vacuity is wider than in the Linga 

 animal. Audital bull^E larger and more inflated than in T. ta7ia and 

 less distinctly triangular in outline. 



Teeth. — The teeth are as in Tupaia tana from Linga Island. First 

 and second upper molars with small but distinct hypocone. 



Measurements. — External measurements of type : total length 363 ; 

 head and body 210; tail vertebras 152; pencil 35 ; hind foot 45 (42). 

 Average of three specimens from the type locality : total length 349 

 (330-362); head and body 197 (17S-210) ; tail vertebras 152; hind 

 foot 44.4 (43.4-45) ; hind foot without claws 41.3 (40-42). 



Cranial measurements of type: greatest length 57.6 (54.6) ;^ basal 

 length 53 (50.4) ; basilar length 50 (47) ; median palatal length 32 

 (30.6) ; length of nasals (joosterior extremity not clearly determinable) 

 21 (20.4) ; distance from lachrymal notch to a tip of premaxillary 

 28.4 (27.6) ; diastema 6 (5.6) ; width of palate at middle of diastema 

 5.2 (4.6) ; width of palate between anterior molars 9 (S.S) ; lachry- 

 mal breadth 19.8 (19) ; breadth of both nasals together at middle 

 3.6 (3) ; breadth of rostrum at middle of diastema 6 (5.4) ; least in- 

 terorbital breadth 15 (14.4); zygomatic breadth 25.4 (25); breadth 

 of braincase above roots of zygomata 19.6 (19) ; occipital depth 12.S 

 (13) ; depth from middle of parietal to lower surface of audital bulla 

 18 (18) ; depth of rostrum at base of nasals 6.6 (6) ; depth of rostrum 

 at middle of diastema 4.6 (5); mandible 39 (36); maxillary tooth- 

 row (behind diastema) 20 (19); mandibular toothrow (behind dia- 

 stema) 17 (16.4). 



Specimens exa?mjzed. — Four : three from Pulo Bunoa, one from 

 Big Tambelan Island. 



Remarks. — The specimen from Big Tambelan agrees in all respects 

 with those from Bunoa. Its hind foot measures 44 (41) mm. Tail 

 imperfect. In color Tupaia bicnocc is very constant, the four speci- 

 mens showing practically no individual variation. The under side of 

 the tail in Tupaia tana is a very deep ferruginous, approaching chest- 

 nut, while the ventral surface of the body is rich tawny ochraceous.

Three specimens from Linga Island agree in all essential characters 

 with those given in the original description of this species, though the 

 color of the underparts appears to l)e darker and that of the lower side
