Tail coarsely animlated with black and pale buff, paler than the 

 hack, the anuulatioiis forming obscure black bands on the upper- 

 siu'face ; under-surface much yellower and less black. A rufous 

 pencil covers the distal half of the lower surface but is not so extensive 

 above where its hairs are tipped and annulated with black. 



Skull and Teeth. — As compared with S. miniatus, Miller, the 

 skull of S. scottii is very much smaller and the rostrum is relatively 

 shorter and blunter. The nasals do not, as is the case with the main- 

 land race, frequently have their posterior terminations (which are 

 serrated, and not V-shaped in combination) markedly in front of those 

 of the premaxillaries but both ai'e practically cotemiinous, thus their 

 median length is relatively greater and they are often actually 

 broader posteriorly. Viewed from above the occipital region is more 

 swollen and three distinct protruberances are visible on the walls of 

 the supraoccipital bone where a central one only can be detected from 

 the same point of view in miniatus. The jrmctions of the lateral and 

 posterior edges of the frontal bone are subangular. The teeth only 

 differ in size. 



Measurements.— Collector's external measurements of type : head 

 and body, 187; tail, 180 ; |hind-foot, 44; ear, 17. Cranial measure- 

 ments : greatest length, 45.1 ; basal length, 38.3 ; palatal length, 20.6 ; 

 diastema 10.3; maxillary tooth-row, 8.9; median length of nasals, 12.6 ; 

 greatest breadth of combined nasals, 6 ; interorbital breadth, 16.8 ; 

 cranial breadth above roots of zygomata, 21 ; zygomatic breadth, 27.7. 



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



Kemarks. — The small size of this squirrel, together with its lighter 

 upper-parts rediiced lateral stripe and white- sprinkled abdomen, 

 strongly differentiates it from its relative occupying the adjacent 

 district of Trengganu and the greater part of the Peninsula. 



It is named in honour of Mr. W. D. Scott, British Agent, Trengganu, 

 whose assistance greatly facilitated and largely made possible my visit 

 to the islands of the Trengganu Archipelago. 



SCIURUS (VITTATUS) PLASTICUS. 



Xloss, Ann. and Mag. Nat. Hist. (8) vii., p. 117, 1911. 



Type.— Adult female (skin and skull). No. 2159/10, Selangor 

 Museum, collected on Great Redang Island, off' Trengganu, east 

 coast of the Malay Peninsula, 1st September, 1910, by C. Boden 

 Kloss. Original No. 3399. 



Characters. — Lilce Scuirus miniatus but smaller, with paler upper- 

 parts and tail and narrower black lateral stripe. Like S. scottii but 

 with the buff element greater in quantity above and the dark lateral 

 stripe more clearly defined, the rufous of the under-parts not extending 

 so near the lips, the white hairs practically absent on the abdomen and 

 the caudal pencil reduced in extent. 



Colour.— Upper-partii a speckle of medium buff and black, the 

 former in excess, the speckling being absent or very fine on sides of head 

 and neck, chui, fore-limbs and hind-feet, which appear greyish buff : an 

 obsolete ochraceous ring round the eve.
