tinct ochraceous tip. The ears are covered with short buff hairs, becom- 

 ing in some specimens ochraceous but never the bright hazel of the belly. 

 Feet darker than the back ; the toes nearly black with a fine ticking of 

 buffy. The under surfaces of body and limbs, except the chin, are clear 

 brig] it hazel mixed on the upper throat with ochraceous hairs which stand 

 in strong contrast and vary in amount from a few in the median line to 

 a distinct patch tapering to the middle of the cbest. The anal region 

 and base of the tail below are like the back, instead of being included in 

 the general chestnut color of the belly. 



Skull. — The skull is distinctly smaller than that of the neighboring race 

 bonhotei of which the Museum has a series from Szechwan. 



Measurements. — The type was measured by the collector as follows: 

 head and body, 240 mm.; tail, 155; hind foot, 51; ear, 24. The skull 

 measures: condylobasal length, 48 mm.; basal length, 45; zygomatic 

 breadth, 20; interorbital constriction, 17; nasals, 14; diastema, 10.5. 



Remarks. — The Museum of Comparative Zoology has a fine series of 

 .S'. c. bonhotei of Szechwan lately described by Messrs. Robinson and 

 Wroughton, so that I have been able to make direct comparison between 

 this and the series from the lower country in extreme southeastern Yun- 

 nan. The larger size, more burly upper surfaces, bright chestnut ears, 

 and clear ferruginous underparts including anus, base of tail, and legs to 

 the sole of the feet distinguish bonhotei at once. From S. c. michianus, 

 described by the same authors,* from Mee Chee, Yunnan, it differs in 

 having the ears much paler than the belly, the hands and feet nearly 

 black, and the hazel of the throat more or less mixed with ochraceous 

 anteriorly. According to Bonhote, typical castaneoventris is found in 

 Fokien to the northeast, and he has described a grayer race from Ningpo. 

 The new subspecies here recognized seems to represent a southeasterly 

 offshoot in the low hill country of this part of Yunnan. 



Dremomys pernyi flavior subsp. now 



Type. — Skin and skull, male, M. C. Z. 13,691, from Mongtz, southeast- 

 ern Yunnan, i'.M 1 . 



General characters. — Similar to D. pernyi but smaller and yellower in 

 general coloration. The median area of the under side of the tail is yel- 

 lowish or buffy instead of whitish. 



Description. — Entire upper surface of the head (except ears), neck, 

 body, limbs, and base of tail a nearly uniform grizzled buff'y and black, 

 slightly clearer buff" on cheeks and hips, and with an ill defined pale buff 

 eyering. Both surfaces of the ears covered with short hairs of a pale 

 ochraceous-rufous, deepest at the posterior basal portion. Chin, throat, 

 belly and inner sides of the legs white, washed with pale buff on the 

 throat. The white hairs, except on the chin, have dark slaty bases. 

 Anal region pale ochraceous-rufous, this color extending on to the base 

 of the tail below, and the inner sides of the tibial margin of the legs. 



Above, the tail is colored at the base like the back, but distally the
