306 Mammals from the Malay Peninsula and Islands. 



Sclurus Tohinsoni alacrisj subsp. n. 



Very like S. robinsoni, Boiih.*, in all essential respects, but 

 the crown is suffused witli buffy, owing to the presence of bufty 

 subterminal rings on the hairs, the fore-back is almost as 

 buffy as the hind-back, and tiie under surface is sharply 

 defined white or creamy white instead of the buff or cream- 

 buff, darkening almost to ochraceous buff on the inner side of 

 the hind legs, characteristic of typical robinsoni. The upper 

 surface is therefore more buffy, and the under surface less so 

 than in the older-known form. 



In the skull the buUai (one specimen only perfect) are 

 rather larger than in the type of robinsoni, and the incisors 

 (of all four specimens) are a little more markedly thrown 

 forward (less vertical), and their front surface is yellow 

 instead of reddisli orange. 



Dimensions of the type (measured in the flesh) : — 



Head and body 105 mm. ; tail 92 ; hind foot 30 ; ear 12. 



Skull: greatest length 34; basilar length 26; greatest 

 breadth 20 ; upper tooth-series 6'2. 



Hab. of fype. Semangko Pass, Selangor -Pahang 

 Boundary ; alt. 3000'. Other specimens from Cheras and 

 Ginting Bidei, Selangor. 



Type. Adult male. B.M. no. 8. 7. 20. 43. Original 

 number 613. Collected 24 February, 1908, by Mr. Herbert 

 C. Robinson, and presented by the Selangor Museum. 

 Four specimens examined. 



This would appear to be a more southern race of S. robin- 

 soni, which was discovered in 1901 by Mr. Robinson on 

 Bukit Besar, a mountain on the Jalor-Nawnchik Boundary. 



Laria insiipiis jalorensis, Bonh. 



Two forms of insighis were described from the Malay 

 Peninsula almost simultaneously by Bonhote t aiid Miller J, 

 the one (^jalorensis) greyish and the other {peninsuUe) a 

 bright and comparatively fulvous animal. 



Whether these are seasonal phases of one form, or are 

 local races inhabiting respectively the high ground (jalorensis) 

 and the low {peninsula^), the material available is not 

 sufficient to show. 



The four adult specimens now received from the Semangko 

 Pass, killed in February, are all of the true jalorensis type.
