This squirrel is primarily distinguished from true mfigenis by its 

 mnch whiter undersurface, and especially its white throat and 

 inner side of thighs. 



Named in honour of Sir Harvey Adamson, K.C.S.I., Lient.- 

 Governor of Btirma, to whom Mr. Shortridge and the Mammal 

 Survey in Burma have both been much indebted for assistance of 

 various kinds. 



Dremomys r. ornatus, subsp. n. 

 The Yunnan red-cheehed 8qttirrel. 



General appearance of rufigenis, but skull characters as in helfieldi. 



Coloration almost as in true rufigenis, but the back a clearer olive 

 without any muddy or drabby tinge, and the rump with scarcely 

 any suffusion of brown. Undersurface as rufigenis. Sides of face 

 brighter ferruginous, the rusty extending further back on the upper 

 surface of the muzzle, nearly to the level of the ears. Patches 

 behind ears buffy. 



Skull very different from that of rufigenis, but indistinguishable 

 from that of helfieldi. Larger than in rufigenis, the muzzle very 

 long, pinched in at sides ; the nasals long, their hinder end directed 

 transverse. Forehead broad, flat, with more transversely directly 

 postorbital processes. Brain case large. Zygomatia widely ex- 

 panded. 



Dimensions of the type. — Hindfoot, 44. 



8Jcidl. — Greatest length 58-2; condylo-incisive length 50-3;. 

 zygomatic breadth 31-6; nasals 21 x 7; interorbital breadth 16-7;. 

 breadth of brain case 25; palatilar length 24*2; p"* and three 

 molars 9*7. 



Habitat. — Yunnan (Probably from near Mong-tze). 



Type.— Old female. B. M. No. 12.7.25.20. Original number 

 11. Collected 4th February 1910 by Mr. Alan Owston's collector 

 H. Orii. One specimen. 



Distinguished from rufigenis by its large skull and long muzzle, 

 and from helfieldi by its brighter coloration. 



Flyi7ig Squirrels. 



No Petaurista is contained in the Popa collection, but one was 

 obtained in the Shan States by Capt. Venning, who has presented 

 it to the survey. It proves to be a new siibspecies and may be 

 called — 



Petaurista lylei venningi, subsp. n. 



Venning's Flying Squirrel. 



Similar in general characters to true Siamese lylei, but with the^ 

 undersurface browner, less ferruginous. 



Size as in lylei. General colour above on superficial view very 

 much as in that animal, the fur with a similar prominent ticking of
