existence of two species, by tlie evident affinity of Sc. Gordoni 

 \o Sc. f/riseopectus and Sc. S/<i(l<ni to Sc. erylhra'us^ ;is well as 

 the fact that the distinctive characters of the former arc those 

 of a widely distributed Chinese species. Mr. W. Sclater * 

 mentions the type of f/riseopectus as bt-ing in the Calcutta 

 Museum and coming from China. This locality has doubt- 

 less been placed on the specimen from its obvious affinity 

 to the Chinese Sc. castaneoventris; but Hlyth was himself 

 ignorant of the exact locality, and as the specimen in the 

 Alusciim agrees with his original descrijjtion, we are, 1 

 think, justified, in default of further material, in assuming 

 Assam to be its true habitat.

Closely resembles Sc. castaneoventris, but may be dis- 

 tinguished by the very pale colour of the underparts, which 

 are sometimes nearly white.

 chow, Dec. 1885 (F. W. Styan). 



Mr. de "Winfon has asked me to correct a note by Mr. Styan 

 in his |)ai)er, quoted above, stating that probaijly Sc. Styani 

 was identical with Gray's M. chinensis. The skull of Gray's 

 type of chincnsis has since been removed and it is evident 

 that M. chinensis, which is a much smaller animal, has no 

 connexion with the present group, but is allied to Sc. lokriah. 

 The exact locality of Gray's type is also very vague, as 

 Mr. Reeves, who procured it, collected over a large extent of 

 country in India as well as in China. 



Sciurus t/uiiwanen'^is, sp. n. (typical form). 



Colour the same throughout and resembling Sc. erythneus 

 erythrvgaster (summer pelage), but slightly darker, each hair 

 having two or three lulvous annulations and varying in 

 colour t'rom very dark brown on the back to greyish on the 

 underjiarts. No red on the undi^rparts, except, in some 

 specimens, a tendency to a reddish patch at the base of the 

 limbs. The outer margin of the ears is slightly lighter than 

 the rest of the body. Tail grizzled for the first half of its 

 length, then black, each hair having a hmg yellowi.'sh tip.
