590 Mr. H. C. Robinson on new 



Colour. — Above silvery grey, somewhat darker on the 

 muzzle, feet, hands, and lower portion of the back, the base 

 of the fur very slightly lighter. General colour beneath 

 similar but paler on the throat, pelage of the chest and upper 

 abdomen with a very decided wash of liver-brown. Tail 

 very finely annulated, dull black, above and below, fnrnislied 

 with a few long whitish hairs towards the ba^e. Vibrissje 

 silvery grey, blackish at the extreme base. No lateral scent- 

 glands in the only specimen (female) available. 



Skull and teeth. — The skull very closely resembles that of 

 C. klossii, but tiie interpterygoid space is narrower and more 

 parallel-sided and the molar series, viewed from above, are 

 less divergent and more parallel, so that the palate a|)pears 

 narrower in proportion to its length tiian is the case with 

 C. klossii. 



Measurements. — Collectors' external measurements (taken 

 in the flesh) : — 



Head and body 102 (97*) mm,; tail 78(69); hind 

 foot 16 (16) ; ear 11 (10-6). 



Skull : greatest length (excl. incisors) 23'8 (•23*0) ; basal 

 length 21-1 (20-9); palatal length lO'S (lOO) ; lachrymal 

 breadth of rostrum 4'9 (4'7) ; greatest breadth above molars 

 7*9 (7*8) ; cranial breadth above mastoid 10*5 (10"5) ; 

 maxillary tootli-row, including incisors, 11"0 (10'8) ; mandi- 

 bular tooth-row (including incisors) 10"0 (lO'O). 



Specimens e.xamined. — One, the type. 



Remarks. — The species seems closely allied to C. lepidura f 

 from East Sumatra, though that form has apparently a longer 

 foot and, relatively to the breadth of skull abov^e the posterior 

 molars, a rather longer muzzle. The skull of the only 

 specimen known is, however, very imperfect. 



Atherurus macrourus jyctnangilis^ subsp. n. 



Type.—MvXi female (skin and skull), No. 341/12,
