294 EODENTIA. 



rather long, but aclpressed, and the hidden portion is almost black, narrowly tipped 

 with the reddish-brown, the sides of the hair being blackish-brown. On the para- 

 chute, only a few hahs have the reddish band, and these are most numerous towards 

 the margin. The tail is rather bushy and but sHghtly distichous, and the hidden 

 portion of its fur is pale fawn at the base, passing into pale chestnut-brown, washed 

 with dusky-brown on the sides and upper surface. The margins of the eyelids are 

 dark brown, and the sides of the face are pale rufous. The ears are moderately large 

 and rounded, rather dark brown towards the tips, and pencilled at the base, anteriorly 

 and posteriorly, with long delicate hau-s. There are no true cheek-bristles, but the 

 moustachial hairs are very long. The under surface is pale ferruginous, palest 

 on the mesial line, and most ruf escent on the outer half of the membrane, the margin 

 of which inferiorly is pale-yellowish. The hairs on the membrane have dark slaty, 

 almost black bases, the ferruginous being confined to the tij)s. The fur of the under 

 parts is very soft and dense. The feet are well clad, more especially those of the 

 hind limbs. The tail is half the length of the body which attains to about 8 inches. 

 It is distinguished from P. cdboniger by its more rufescent colouring and by the 

 pencilling of its ears. 



It occurs in Sikkim and Upper Assam, from whence Blyth first obtained it. 

 Mr. Bonynage, who presented the typical specimens to the Asiatic Society of Bengal, 

 also gave one to Mr. Walker, who referred it to P. sagitta. As already stated, I 

 obtained two specimens of this species at Teng-yue-chow. 



The type of P. kaleensis, Swinhoe, from Formosa is in the British Museum, and 

 it agrees exactly in its colour and in the pencilling of its ears with this sjoecies, of 

 Avliich I believe it to be an example. 



Dr. Gray described tliis flying squirrel as about one-third smaller in length and 

 breadth than P. caniceps, of which he was at first inchned to regard it as the young, 

 but he afterwards states that the bones of the typical specimen show no indication 

 of youth. The type was procured at Darjeeling. Temminck also lays stress on the 

 fine silky tufts at the base of the ears, by which he states it is distinguished from 

 i ts congeners. He procured it in the Island of Sumatra. 



I have examined the type of P. setosus, which agrees with P. pearsonii in the 

 absence of cheek-bristles and in its general characters, but the specimen is not fully 

 grown, measuring only, along the back to the root of the tail, 4-75, and the tail 3-75. 

 It is less rufescent than the adult, and the under parts are wliiter, as are also 

 the cheeks.

This is a medium-sized squirrel, about the dimensions of P. fimhriatus. It
