308 Mr. E.. C. WrougMon on the Forms of Squirrel 



Head and body 190 mm. ; tail 190 ; hind foot 42; ear 20. 



Skull : greatest length 47 ; basilar length 37 ; zygomatic 

 breadth 28 ; brain-case breadth 22 ; interorbital breadth IT*)) ; 

 nasals, length 15, proximal breadth 3*5, distal breadth 6*3 ; 

 diastema 10*6 ; upper molar series 9*6. 



These skull-measurements are taken from a rather old 

 individual. 



(5) Sciurus Jinlaijsoni, Horsf. 

 1824. Sciurus finlaysoni, Horsfield, Res, Java. 



The type-locality is the island of Sichang. 



The animal is completely white and Is expressly stated to 

 have black eyes and black soles to the feet. 



Dimensions of the type (an old animal) : — • 



Head and body 175 mm.; tail 175; hind foot 43; ear 20. 



Skull: greatest length 4G : basilar length 36"5; zygomatic 

 breadth 28; brain-case breadth 22; interorbital breadth 17*3; 

 nasals, length 13, proximal breadth 4*5, distal breadth 7*3 ; 

 diastema 11 ; upper mohir series 8. 



(6) Sciurus harmandi, A. M.-Edvv. 



1870. Sciurus hannandi, A. Milne-Edwards, Bull. Soc. Philom. (6) xii. 

 p. 8. 



The type-locality is Phu Kok, an island off Chantaboon. 



General colour above near " walnut-brown," but almost 

 completely hidden by white, the individual hairs each half 

 grey, half walnut-brown^ in that order from the base upwards ; 

 with a very large proportion of longer, wdiite, black-tij^ped 

 hairs; below white, largely tinged with walnut-brown. 

 Cheeks and throat darker. Limbs brown, faintly grizzled 

 with buff'; liands vinaceous cinnamon, feet cinnamon-rufous. 

 Tail like back at immediate base, thereafter mixed black and 

 white, i. e. hairs black with white tips (according to M. -Ed- 

 wards these white tips are tinged with reddish in the type). 



Milne-Edwards gives the dimensions as : head and body 

 2G0 ram. ; tail 250 — but these were probably taken on a 

 skin or stuffed specimen. The tiue size is apparently exactly 

 the same as that of cinnamonieus. 



The following are measurements of an adult skull : — 



Greatest length 5G mm,; zygomatic breadth 32; brain- 

 case breadth 24*5; interorbital breadth 20 ; nasals, length 16, 

 breadth proximally 4*5, breadth distally 7*2; diastema 12*5; 

 upper molar series 11. 



Tiie dorsal pattern is like that of bocourti dextralis^ but the 

 black and white tail serves to distini^uish it at once.
