2 2 ) from Chanda (500'); 5 (3 c? , 3 $ ) from Chickpalli (1,300'), 

 Total 27 (16c?, H $)• ^11 these specimens were collected for the 

 Mammal Survey by Mr. C. A. Crump ; those since presented to the 

 British Museum are registered under the serial number 12-1 1*29. — 



Description : — In external appearance, size and proportions the 

 present race is very similar to R. r. arhoreiis. The general dorsal 

 colour is still colder, or greyer, on the average, than in the latter 

 subspecies; and the long black hairs of the back show a more 

 evident tendency, in narbadce, to form a mid-dorsal stripe of black. 

 The belly is white or pale yellow, sharply contrasted with the 

 flanks; usually the ventral hairs are light throughout, but in some 

 specimens they have slaty bases — a feature not seen in any of those 

 from Bihar and Orissa. The feet are light above and show in 

 some individuals a yellowish tinge or obscure dusky markings. 

 The mammar}'^ formula of females is normally 2-3=10; but in the 

 type and two or three others it is 3-3=12; narbadce is apparently 

 more variable in this respect than is arhoreus. 



The average dimensions of 26 adults (head and body ranging 

 between 132 and 173) are: — 



154_209— 31-6— 23 = 100— 136— 20-5— 14-9 



The following table shows the variation in the proportions which 

 accompanies the increasing length of the head and body : —

The skull is slightly smaller than in arhoreus (condylo-basa 

 length averaging 38-4 instead of 39-5). The temporal muscles 

 appear to be weaker (about as in li. r. frugivorus) ; for while the 

 cranial width is relatively as great as in arhoreus, the intertemporal 

 distances (dimensions 6 and 7) are relatively greater and the zygo- 

 matic breadth is relatively less (see Table fl) ; the parietals usually 

 articulate by tongues with the supraoccipital above the temporal 

 lines. The palatal length is shorter relatively — a difference appa- 

 rently due to a shortening of the rostral portion of the palate.
