736 OLDFIELD THOMAS.

Dimensions of the type, measured in the flesh : 



Head and body 315 mm.; tail 295. 



Skull, condylo-basal length 61 ; upper length 58.5; zygomatic breadth 34.3; nasals 

 21X8.8; intertemporal breadth 6.8; breadth across bullae 30 ; palatilar length 32.5; dental 

 length 31.5; combined length of three anterior molariform teeth 11. 



Hab. and Type as above. 



This Pseudochirus is no doubt nearly allied to caroli, which is a native of the VVeyland 

 Mountains, to the north of the Nassau Range. But its differently shaped nasals, the shorter 

 extent of the naked part of the tail, and its detailed différences in colour would seem to 

 indicate spécifie distinction. 



With the concurrence of Dr. DE BEAUFORT I hâve named it in honour of its captor, 

 Dr. VERSTEEG, who did most of the collecting on the Dutch Expédition of 19 12.

A very small species allied to P. scldegeli, 



Size, as judged by the teeth, decidedly less than in P. forbesi, therefore still less when 

 compared with schlegeli. Fur long, soft and woolly, hairs of the back in a young spécimen 

 about 20 mm. in length, without including the longer piles, which overtop the others by 

 about 8 mm. General colour above dull fulvous grey, the head slightly paler. Undersurface 

 whitish, with a faint buffy or fulvous tinge, the hairs slaty for three fourths their length. No 

 trace of a médian dorsal line in the head. Eyes with a slightly darker area below them, and 

 another between them and the ears. Ears small, thickly clothed behind with soft hairs of a 

 fulvous or pale rufous colour; below and behind the ears, from their bases to the middle of 

 their hinder edge, a prominent white patch. Forearms vvashed with pale rufous. Hands white, 

 slightly tinged with fulvous; feet quite white. Tail at base of the same buffy grey colour as 

 the back, becoming rather more drabby on its middle third, and tending to brown on its 

 terminal, shorthaired, third ; centre of underside drabby at base, then more brovvnish, the 

 terminal two fifths naked. 



Skull and teeth of the usual structure in the group, the molars decidedly smaller than 

 in forbesi. Bullae well swollen. 



Dimensions of the type, a young spécimen, measured on the skin : 



Head and body 152 mm.; tail 173, its naked part below 75; hindfoot 22. 



Skull, greatest length 38 ; combined length of first two molariform teeth 6. 



Hab. as above. 



Type a young skin, with its skull. B. M. N°. 22. 2. 2. 69. Original number 89. Collected 1912^ 



This species is apparently most nearly allied to P. schlegeli, Jentink, but differs by 

 its pale-coloured, not blackish, ears, the absence of a médian dorsal line, the white instead
