296 Mamaia OF INDIA. 
common: Malabar, Travancore (the Marquis of Tweeddale, according 
to Dr. Anderson, got a specimen from this locality of a much 
lighter colour than usual), the’ Bustar ‘forests in Central India, 
Vindhian mountains near Mhow, the Northern Circars, and the Midna- 
pore jungles. 
No. 298. PTEROMYS CINERACEUS. 
The Ashy Flying Squirrel, 
NATIVE NamMeE.—Shau-byau in Arakan. 
Hapitat.—Assam, Burmah, viz. Arakan, Pegu and Tenasserim 
provinces. 
DEscRIPTION.—Very like the last, but with a greyish fur, and almost 
white tail, with a black tip. 
The fur generally is a mixture of pale grey and brownish, the hairs of 
the head and back having a whitish subterminal band; the tail consists 
almost entirely of the greyish hairs; the parachute is reddish brown ; 
the under-parts white. Blyth, however, mentions a specimen from 
Tenasserim which is unusually rufous, with the tail concolorous with the 
upper parts. 
Si1zE.—Same as the last. 
It is open to question whether this is not identical with Preromys oral, 
merely a local variety. Blyth so termed it ; and from what Dr. Anderson 
has written on the subject, I gather that he, too, inclines to the same 
opinion, as he says: “ The dimensions are the same as those of P, oral, 
Tickell, of which it will probably prove to be a local race,” 
No. 299. PTEROMYS YUNNANENSIS. 
The Yunnan Flying Squirrel. 
Hapitat.—Kananzan mountains ; Burmo-Chinese frontier. 
DescriPTION.—Dr. Anderson, who discovered and named this species, 
describes it as follows: “‘The general colour is a rich dark maroon 
chestnut on all the upper parts, the head and back in some being finely 
speckled with white, which is most marked in the young, but is always 
most profuse on the posterior half of the back, which in some individuals 
has almost a hoary tinge, from the extent to which the annulation of the 
hairs is carried. 
“Tn the adult, the upper surface of the parachute is of the same 
colour as the back, and the hairs are not annulated, except along its 
margin ; but in younger specimens they are partially so on the upper 
surface, as are also the hairs on the first three or six inches of the tail, 
which are concolorous with the back, but broadly tipped with black, 
while the remaining portion of the tail is rich glossy black ; the sides of
