Mountains and it seems probable that the place of Neodon is 

 supplied by one or other of these two species of Eothenomys. 



Allen states that " the series of ten specimens brought back 

 by the Second Asiatic Expedition is from the same range, at the 

 following localities : Ssu-shan-chong, 9000 feet ; Peswi, 10,000 

 feet; Ssu-shan (Snow Mountain), 12,000 feet; timber-line 13,000 

 feet. Evidently it is a species of high levels."

Type.—BM., No. 11.9.8.122; adult female, collected by 

 Malcolm P. Anderson, March 19, 1911 ; presented by the Duke of 

 Bedford. 



Type locality. — Chao-tung-fu, Yunnan. Altitude 6700 feet. 



Mange. — Western Yunnan. 



Characters. — A small greyish-brown species, with simplified 

 m^ and complex m^. Size small (hind-foot 16 mm. ; condylo- 

 basal length to 24 mm.). 



General colour less warm brown than in other species. Upper 

 parts greyish-brown, near sepia; under parts dark slaty grey 

 (rather more smoky than " grey No. 5 "). Hands and feet 

 brown. Tail dark brown above, little lighter below. 



Skull in general form like that of E. melanogaster but smaller, 

 with the auditory bullae relatively a little smaller. 



Cheek-teeth; iv?-, as in E. proditor, with only thxee inner 

 salient angles ; m^ with its third inner salient angle normally 

 developed ; m^ quite unreduced with four salient angles on each 

 side, its first outer infold often shallow, imparting an AUicola- 

 like appearance to the anterior loop ; m.^ with third outer angle 

 more reduced than is usual in Eothenomys. Other teeth normal. 



Eor external and cranial measurements, see tables at end of 

 volume. 



Remarks. — Mr. Allen says that three specimens were obtained 

 by the American Museum Asiatic Expedition at an elevation of 

 7000 feet on the Mucheng-Salween Divide, Western Yunnan, 

 and he remarks that the species is apparently the least common 

 of the members of the genus in Yunnan.
