Characters. — Intermediate between Ratufa ajfinis afjinla (Raf- 

 fles.), from Singapore Island, and Ratvfa affinis anreiventer (Geoffr.), 

 from the territory of Malacca. From the former it differs in having 

 the hands the feet concolorous with the rest of the limbs and in the 

 reduction of the dark area on the cheeks and ears and from the latter 

 in having the lielly pure white, sharply differentiated from the 

 sides. 



Colour. — Bleached pelage. Above pale cream, head darker and 

 more l)uft.y, the hairs without any visible annulations. Muzzle, a 

 patch beneath and in front of the ears, whitish. A narrow ring- 

 round the eye seal-l)rown. Ears pale seal-l)rown on their (,)uter aspect, 

 more or less ochraceous on the inner side. Limbs from the shoulders 

 and thighs ochraceous-) tuft', hardly paler on the hands and feet. A 

 stri])e of paler ochraceous-buif from the shoulder to the thigh, inter- 

 rupted by a not very conspicuous white patch on the outer aspect of 

 the thigh. Tail whitish-l»rown above, beneath with the proximal half 

 of the hairs whitish, the tips mingled brownish and buffy. Midril) 

 whitish-brown, beneath pure white quite sharply defined from th<i 

 sides. 



Measurements. — Collector's external measurements taken in the 

 flesh: head and body, 300; tail, 405; hind-foot (without claws) 70: 

 ear 25 mm. Skull: greatest length, — ; basilar length, — ; zygomatic 

 lir«'adth, 41.5 ; greatest length of nasals, 21.8 ; diastema, 14.9 ; cranial 

 l>i-eadth, 31.1 : interorbital l>readth. 2(3.3 ; upper molar series, 13.3 mm. 



Remarks.— Mr. Miller has already (loc cif. siq^ra) remarked that 

 the Johore pak^ Batvfa wmild probably prove distinct from that of 

 Singa])ore, while Prof. Trouessart has applied a name, withovit descrip- 

 tion, wiiich we have adopted. Besides the type we have seen other 

 specimens from the Sembrong River further south in Johore, but these 

 were in bad condition and without skulls or measurements.
