Specimens Examined.— Twenty-nine, all from the type locality. 



Kemarks. -Its slightly smaller size and paler colouring sufficiently 

 separate this race from the mainland animal, while diiferences in size 

 and colour of the upper-parts, and the more marked lateral stripes, 

 distinguish it from the other allied forms of the Trengganu Archipelago. 



SCIUIIUS (VITTATUS) PROTEUS. 



Kloss, Ann. and Mag. Nat. Hist. (8) vii., p. 118, 1911. 



'Pype.— Adult male (skin and skull), No. 2094/10, Selangor 

 Museum, collected on East Perhentian Island, off Trengganu, east 

 coast of the Malay Peninsula, 13th September, 1910, by C. Boden 

 Kloss. Original No. 3645. 



Characters.— Smaller than 8. miniatus; differs from S. perhen- 

 tlaul in being much paler above, while below the rufous is replaced by 

 buff" ; the dark lateral stripe much obscured by the buff tips of 

 the hairs. 



Differs from H. latesceus* Miller, of Sirhassan Island, and other 

 allied races of Natuna Islands squirrels in possessing a notable rufous 

 pencil to the tail. 



Colour. — Upper-parts a coarse speckle of pale buff' and black, the 

 buff' being in excess : sides of head and neck, chin, fore- and hind- 

 limbs almost pure pale buff' but dulled by the visible grey bases of the 

 hairs, fore- and hind-feet clearer and less grey : a buff ring round 

 the eyes. 



Under-parts buff, palest on throat, axillae and limbs (cream-buff) ; 

 darkest on chest and down the median line of the abdomen (intense 

 buff'). 



Pale lateral stripe cream buff (7-8 mm. wide), hairs of dark lateral 

 stripe with blackish bases and buff tips, the general colour impression 

 thus produced being a dark yellowish grey. 



Tail, above, coarsely anuulated black and pale buff, the annulation 

 forming obscure bars ; below, pure buff like the abdomen near the base, 

 elsewhere with the black grizzling much reduced. A rufous pencil 

 extending one-third up the tail below but much less above, where it is 

 tipped and annulated with black. 



In females the inguinal mammae are surrounded by patches of 

 white hairs about 13 mm. in diameter. 



Skull and Teeth. — The skull is like that of 8. perhentiani but is 

 a little smaller, the combined nasals are narrower and have a regular 

 V-shaped termination, and the angle formed by the sides and posterior 

 edge of the frontal bone is less obtuse owing to the greater breadth of 

 the latter. 



As compared with S. plasticus, than which it is both a little longer 

 and narrower, the terminations of the nasals are rather more anterior
