This beautiful little Flying Squirrel is readily distinguislied from 

 the majority of the oriental species of Hylopetes by its comparatively 

 large ears, in which respect it agrees with P. alboniger, a larger species 

 with much larger teeth. It has a strong superficial resemblance 

 to Belomys jpearsoni, but is undoubtedly a Pteromys. 



It is named after its collector, Mr. P. M. Leonard, to whom the 

 Bombay Natural History Society is indebted for the interesting 

 series of mammals of which it forms a part.

 The undersurface of this squirrel is of a paler and brighter rufous 

 than that of the nearly allied C. c. bonhotei of Sze-chwan. 



While making this comparison I have noticed that the squirrel 

 of this group from Sze-chwan referred by Mr. Glover Allen (Mem. 

 Mus. Harvard. XL. No. 4, p. 233, 1912.) to C. c. bonhotei is certainly 

 not that form, and needs description. It may be called : — 



Callosciueus castaneoventeis gloveri, sp. n. 



Much smaller than G. c. bonhotei. Back paler and more suffused 

 with buffy. Under surface brighter rufous, about as in aquilo, 

 this colour running down the legs to the heels. Ears prominently 

 ochraceous, those of bonhotei uniformly like head. Tail grizzled 

 greyish, much paler than in bonhotei. 



Dimensions of the type : — 



Head and body 212mm. ; tail 195 ; hindfoot 53. 



Skull, greatest length 50.5 ; condylo-incisive length 45 ; upper 

 tooth series, exclusive of p^ 9.6. 



Hab. — Nagchuka, Western Sze-chwan. Alt. 10,000'. 



Type.— Mult female. B. M. No. 13. 9. 13. 3. Collector's number 

 230, Harvard number 7829. Received in exchange from the Museum 

 of Comparative Zoology, Harvard. Collected 14 August 1908, 

 by W. E. Zappey. 



Named in honour of Mr. Glover Allen, in whose excellent paper 

 on Sze-chwan mammals this not unnatural error of determination 

 occurs. With the type and several other specimens before me I have 

 been enabled to correct the naming with confidence.

 The striped undersurface is very variable both in the intensity 

 and in the relative proportions of the black and white lines, the Sima 

 series alone showing all the extremes. Some specimens have very
