Blyth described this form on two adults and a small young specimen 

 from Arakan, which are listed above, and another adult in worn pelage 

 and unusually rufescent with darker tail than ordinary, from Tenasserim, 

 which is the second specimen of Petaurista taylon [cf., supra). Specimen

 of Pteromys alborufus (Sclater, loc. cit.). In this stuffed specimen the 

 tail is whitish.

In this small series all gradations from a form with a clearly defined 

 median stripe on the back to one with no stripe at all are present. In 

 view of Hodgson's specimen above which has the upper surface un- 

 grizzled I have used his name for the species rather than the later one 

 P. nohilis, Gray, which has been adopted by Wroughton {Journ. Nat. 

 Hist. Soc. Bombay, XX, p. 1020; 1911) who has transferred P. magni- 

 ficus as a synonym to the larger grizzled form to which he has applied 

 the name P. alhiventer, Gray.
