retaurista marica, sp. n. 



A wliitc-spotteil species near P. pitnctatus*. 



8ize, jutl;;in<^ by skull, about as in /'. puncfafus. Fur 

 very soft and (inc. General colour above, a[)art from tbe 

 white spots, approaching " tawny olive/' becoming more 

 tawny posteriorly and on the patagium, the hairs subter- 

 niinally ringed with buffy or ochraceous; anteriorly the 

 colour darkens to blackish, the ends of the hairs on the crown 

 glossy black. Up|)er surface of head and body with a variable 

 number of pure white spots, each about ^—}j inch in diameter, 

 the least S|)otted of the three specimens iiaving about thirty 

 spots and the most s|)otted perhaps double that number, with 

 the head particularly profusely spotted ; in none, however, 

 are the spots so numerous and widely spread as in the type 

 of P. punctaius. Patagiuni tawny above, brilliant ochraceous 

 rufous below. Under surface bright ochraceous buff; a dark 

 brown spot on the chin. Hands irregularly marked with 

 dark brown and deep tawny; outer sides of legs and upper 

 side of feet rich ochraceous rufous ; the digits in one specimen 

 jjartly brown. Tail ochraceous rufous, some of the hairs 

 subterminally ringed with blackish and bufFy ; tip more or 

 less washed with blackish. 



Skull like that of the type of P. punctafus, but there is a 

 striking amount of variation in its general outline, especially 

 in that of the muzzle, this being long and narrow in No. 3, 

 short and broad in No. 2. 



Dimensions of the type (measured in the flesh by the 

 Japanese collector) : — 



Head and body 365 mm.; tail 380; hind foot 63; ear 44. 



Skull : greatest length 63 ; condylo-incisive length 59 ; 

 greatest breadth 42; nasals 19'7xll*4; palatilar lengtli 

 29*5; palatal foramina 4"7 ; upper tooth-series exclusive of 

 y 12-6. 



JJab. Yunnan (probably near Mong-tze). 



Ti/pe. Adult male. Original number 1. Collected 29th 

 January, 1910, by Orii. 



This beautiful flying-squirrel is most closely related to 

 P. punctatus, but ditlers by its more yellowish general 

 colour, its blackish head, and bright rufous tail and feet. 

 The fact that all three specimens are spotted shows that this 

 character in P. punctatus is a normal one, and not a mere 

 individual aberration, as has been sometimes supposed. 



* Fetaurista is masculine, so that the masculine form of adjectival 

 names must be used for the species. But if tlio names are substantives in 

 apposition the more euphonious feminine form is permissible.
