518 On Insectivdres and Rodents from X.W. Yunnan. 



Fur long and soft; hairs of back about 11 mm. in lencrfli. 

 General colour above rather warmer than " broccoli brown " ; 

 head more greyish brown. Under surface paler brown, the 

 hairs of the belly washed with wood-brown^ but those of the 

 throat, chest, and axilloe with greyish tips. Ears short, 

 brown, little prominent. Hands and feet greyish white 

 above; hind foot-pads 6. Tail short, dark brown above, 

 greyish below. ^lamniEe — 2 = -l. 



Skull with the characteristic shape found in the three 

 subgenera, Eothenomys^ AnteVwmys^ and Caryomys^ the upper 

 surface smooth, rounded, without marked ridges, the inter- 

 orbital region broad, short, its edges rounded and its middle 

 line flat or cnncave, witliout tendency to form a median crest. 

 Palatal foramina somewhat dilated in their anterior third. 

 Bullae rather small, slightly larger proportionally than in 

 M. wardi. 



Teeth. — First upper molar with spaces 4 + 5 generally 

 though not always open, the other spaces always closed. 

 M^ with spaces all closed, a small projecting angle on the 

 inner side of its fourth prism, corresponding to the prominent 

 postero-internal angle formed in certain species of the group. 

 M^ long, comi)licated, about as in M. wardi and M. chinensis 

 chincnsisj its front end with an Alticola-\\ke double space, 

 spaces 1 + 2 broadly connected; spaces 3 + 4 also connected; 

 its inner side with four prominent salient angles and one 

 or even two smaller posterior ones; outer side with 4— 5 

 smaller angles. Lower teeth, as usual, with all the spaces 

 open and o]iposite, 7»i with 4 outer and 5 inner salient angles.

This interesting species shows a certain approximation 

 towards the subgenus Caryomys, but its long complicated >»' 

 with an Alt'icola-\\\iQ anterior end, with Sj)ace3 1 + 2 open, 

 and its usually open spaces 4 + 5 of ??t*, indicate that its proper 



* Range 3o-48. 



t Larger than most ; another adult skull measures 230 mm. in 

 condylo-incisive length.
