usual. Extreme length of skull from occiput to end of nasals 2, 

 basal length 1'75, zygomatic breadth 1-15. 



Distribution. Assam, the hills to the south (Khasi, Garo, Ac.), 

 Cachar, Chittagong, Manipur, and Upper Burma ; also (if, as I 

 believe, S. castaneoventris is not distinguishable) China. S. piceus 

 is said to be from Tenasserim. 



Varieties. The following are the principal races that I include 

 under S. erythrceus : 



1. Typical S. erythrceus from the Khasi hills and neighbourhood. 

 This has the upper surface light olive, lower parts chestnut, 

 and the terminal portion of the tail, two thirds or more, 

 coloured like the belly, the extreme tip sometimes whitish ; 

 the ears are rufous. 



2. S. erythroyaster from Manipur. Upper surface dark olive, 

 lower parts chestnut to bay, feet and terminal half or more of 

 the tail black. 



3. S. punctatissimus (and, as I believe, /S. piceus of Peters) from 

 Cachar. Upper parts very dark almost black, tail and feet 

 black, lower parts dark bay. 



4. S.yordoni from Upper Burma, north of A va. The upper parts 

 brown or olive, more or less rufescent ; lower parts pale to 

 deep ferruginous, with a distinct median band along the breast 

 and abdomen coloured and speckled like the sides, the throat 

 and fore neck sometimes speckled olive, sometimes ferruginous. 

 Tail annulated, tip rufous or white, sometimes a black bar 

 between the annulated part and the rufous or white tip. A 

 very similar variety is found in Upper Assam. 



5. S. sladeni from Thigyain, Upper Burma. Upper parts 

 speckled rufous-olive. Head, feet, termination of the tail, and 

 all the lower parts ferruginous red.

 belly white, with three longitudinal dark brown or black stripes,

 between the white and the olive of the side ; the white is sometimes 

 reduced to two narrow stripes. Tail the same colour as the back 

 except at the tip ; tail-hairs annulated with yellow or whitish and 

 black, four or five rings of each colour, terminal hairs black with
