MAMMALS FROM YUNNAN AND TONKIN. 

 BY GLOVER M. ALLEN. 



The Museum of Comparative Zoology has lately received a 

 small collection of mammals from Tonkin and the neighboring 

 portion of southeastern Yunnan, China. These were obtained 

 from the same region whence the British Museum recently had 

 a collection containing sundry remarkable novelties, described 

 by Thomas and Dollman. Two of the squirrels in this second 

 collection seem to represent undescribed races, and these are 

 here named. I have also appended some additional notes on a 

 line adult male of the new snub-nosed monkey of Tonkin de- 

 scribed by Dollman. 



Sciurus castaneoventris haemobaphes subsp. now 



Type.— Skin and skull, male, M. 0. Z. L3.693, from Chih-ping, south- 

 eastern Yunnan, L'b' February, 1911. 



General characters. — A small squirrel of the castaneoventris type, differ- 

 ing from other described forms in the combination of blackish ringers and 

 toes, buffy to pale ochraceous ears ; the mixture of ochraceous hairs with 

 the otherwise clear hazel of the throat, producing a more or less yellow 

 patch, and the restriction of the bright hazel of the inferior side of the 

 hind legs to a narrow area that does not quite reach the heel and docs 

 not include the anus and base of the tail. 



Description. — Head, including checks and chin, dorsal surface of body 

 and of limbs except the feet a uniform grizzled cream butt" and black, 

 slightly darker over the mid-dorsal area, where the individual hairs are 

 either entirely Mack or black with one or two hurt' rings. Those with a bully 

 ring of about 2 nun. and a long black tip of 6 or 8 mm. predominate. 

 On the tail these rings increase in number and extent, and form on the 

 terminal two-thirds indistinct transverse hands, with an outer fringe 

 formed by the long hurt' or ochraceous tips. At the tip of the tail the 

 terminal ochraceous hand and the subterminal black portions of the hairs 

 are much longer then elsewhere and form thus a black patch with a dis-
