187 



Skull ■ "reatost leugtli 27-5 nun. ; coiidylo-incisive length 24-8 ; 

 interorbititl breadth 47; palatilar length 11-8; palatal fora- 

 mina 5-7 ; upper molar series 4-2. 



Typical locality. Mt. Oini, W. Sze-chwan. 6000-lU,UUU . 



Tvi^e. A<lult male. B.M. No. 11.2.1.170. Original number 

 2535. Collected 18 August, 1910. 



This subspecies differs from 'peninsuUe by its darker colour and 

 from the W. Fokieu draco B.-Ham. by its larger size, longer tail, 

 and less rufous tone. . 



The Wei-choe series of the present collection contains examples 

 agreeing with «e»/7iSK7fP and others with orestes, and on exami- 

 nation it proves that all of the latter are from altitudes above 

 7000' while all of the former are below that height. On the 

 other hand, on Mt. Omi those from 6000' are of quite the same 

 colour as those from 9000', so that it cannot be said that the 

 darker colour is a direct result of the altitude.

 Type. Adult male. B.M. No. 11.2.1.156. Original number

This distinct large-eared form would seem to range over the 

 mountainous country to the west and south of the area inhabited 

 by A. s. orestes.
