number of long black hairs, which are interspersed among the other ones, these 

 being especially evident on the nape and hindneek. Sides of the eye and below 

 same a well-marked black area. Above the eyes pinkish cinnamon continued back- 

 wards, thougli darker and mixed with buff, to the ears. The black tuft behind the 

 ears rather small and ill-defined. Under parts of body bright cinnamon rufous. Hands 

 wholly dark, except for a narrow rufous area at the middle part, extending to the 

 digits. The black colour of the hands continued as a narrow black line up to the 

 shoulder and along the outer side of the hands. Feet and an area around them, 

 blackish brown. Base of tail together with the upper part of same like the posterior 

 part of the body, then påle cinnamon for its greatest length and with a brownish 

 black tip. 



This new form differs, as seen by the description, from its nearest relative in 

 having a pinkish cinnamon area above the eye. The black tufts behind the ears 

 are small and undefined, while in P. p. rajah they are heavily tufted forming a 

 conspicuous patch on each side. 



As already shown by Wroughton (Journ. Bombay Nat. Hist. Soc. 1911, p. 

 1012) Pallas' applied the specific name petaurista to the Javan animal many years 

 beforeDESMAREST established nitidusioi the same form, and that name must therefore 

 be substitued for nitidus in Mr. Thomas' paper.
