48.2.11.2, and a skin and skull without locality, Reg. No. frhi'-^iAi- 

 From the account in the original description one would be inclined 

 to take the specimen in alcohol as the type, but because a colored 

 plate of the entire ammal is given, one is justified in regarding the 

 skin as the type. This has been done by authors generally, Mivart, 

 Anderson, and Thomas.^ Tliis course is rendered imperative by the 

 fact that an examination of the specimen in alcohol shows it to be an 

 immature example of Tanatana, the first upper molar not being through 

 the gum, and just appearing through the alveolus. The skin, Reg. No. 

 47.7.8.13, is mounted and in good condition, probably a female; the 

 only original information concerning it is *'Ex. coll. Verreaux." ^ 

 The skull, Reg. No. 48.1.27.14, is in fairly good condition, but con- 

 siderably damaged on the right side about tlie palate. 



GeograpMc distribution. — Probably the entire island of Borneo, but 

 Imown records are only from southern portion. See No. 37 on map 

 on page 75. 



Diagnosis. — About the size of or slightly smaller than T. glis fer- 

 ruginea, upper parts seal or walnut brown, tail similar to body, its 

 hairs without amiulations. Mamma3, probably 2-2 = 4. 



Color. — General color effect above something between seal brown and 

 walnut brown, with indistinct grizzling with ferruginous posterior to 

 neck, becoming almost obsolete on the rump, anterior to the neck 

 color lighter and grizzling more distinct ; in the type, top of neck and 

 shoulders and sides something of a color between bay and chestnut; 

 under parts anterior to chest, buffy in the type, ochraceous buffy in 

 other specimens, posterior to chest tawny ochraceous; tail above 

 similar to back, below tawny in center line, outer edges like back, 

 hairs of tail without annulations; shoulder stripe rather poorly de- 

 fined, tawny ochraceous. 



Slcull and teeth. — The skull and teeth of Tupaia splendidula are of 

 the same general form as those of T. glis ferruginea, but are dis- 

 tinctly smaller, with smaller and more oval incisive foramina, and 

 relatively larger orbits. The type has a slightly wider rostrum and 

 wider brain case than Cat. No. 151883, U.S.N.M. (Plate 10, fig. 11.) 



Measurements. — Type: Head and body, 190mm. ; tail, 140 (bothfrom 

 mounted skin); hind foot, 40; condjdo-basal length, 45; zygomatic 

 width, estimated, 27; width of brain case, IS; maxillary tooth row, 

 17.5. Collector's measurements of head aiid body are 173-188; tail, 

 130-157. Measurements of two adult skuUs are: Condylo-basal 

 length, 43.5-44; zygomatic width, 24.5-24.5; width of brain case, IS- 

 IS. 5; maxillary tooth row, 16.5-18. See table, page 87. 



Remarlcs. — Tupaia splendidula is a well-characterized species and 

 representative of a rather definitely marked group. As seen on 

 Borneo and as represented by geographic forms in the Natuna 

 Islands, it is very different from mem^bers of the wide ranging /er- 

 ruginea group, yet it seems to be not very distantly removed from it.
