duller; sides of body and outer side of legs similar to upper parts, 

 but slightly grizzled ; top of nose a grizzle of raw sienna and blackish 

 gradually blending on top*of head with color of upper parts; under 

 parts buff to olive buff; inner side of legs similar to sides of body, but 

 lighter; tail above like back, under side of tail and bases of tail hairs 

 generally tawny ochraceous, with outer and terminal margins of tail 

 below, dark tav/ny; shoulder stripe buff, or ochraceous buff. Cat. 

 No. 10-1715, U.S.N.M., has the central portion of the tail orange 

 ochraceous in color, being fully as bright as the tail of T. lucida. 



STcull and, teeth. — These are of the same general form as they are in 

 Tupaia splendidula, but the skull averages longer and has a more 

 inflated braincase; the teeth are larger. (Plate 10, fig. 12.) 



Measurements. — Type: Head and body, 184 mm.; tail, 140; hindfoot, 

 40; condylobasal length, 46; zygomatic width, 25; width of braincase, 

 19; maxillary toothrow, 18. For measurements of individuals, see 

 table, page 87. 



Remarli's. — Tupaia natunx is closely related to T. splendidula, so 

 much so that Thomas and Hartert in 1894^ considered them the 

 same species. At that time there were no definite records of Tupaia 

 splendidula from the island of Borneo, the only available material 

 being the type of unknown locality. They arrived at the conclusion 

 that the type had not been obtained on Borneo, but had probably 

 come from the Natuna Islands. Since Doctor Abbott has obtained 

 specimens on Borneo almost identical with the type there can be but 

 little doubt that it was origina,lly collected on that island. ^ In work- 

 ing with the treeshrews in 1904 Mr. Miller in manuscript notes had 

 come to the conclusion that the Bunguran splendidula was distinct 

 from true splendidula and had applied the name natunse to it. 



Specimens examined. — Six. All from Bunguran. See table, page 87.
