The following table shows the variation in the proportions at 

 successive stages of growth : — 



It would appear frona this table, that, as in B. r. tistce, the tail 

 is relatively much shorter in younger or smaller individuals than it is 

 in the corresponding stages of growth of the lowland subspecies ; 

 and fui'ther that its relative length does not decrease so rapidly or 

 regularly with growth or increased size as in lowland forms. 



The skull is large (average condylo-basal length 40*8), agreeing 

 in this respect and in cranial and intertemporal breadths with 

 -R. r. alexandrinus. The temporal wings of the parietals are large, 

 their lengths being equal to at least half the full length of the 

 squamosals ; the parietals articulate with the supraoccipital above 

 the temporal lines by means of broad tongues. The nasals are 

 distinctly larger ; the palatal length of the anterior palatal foramina, 

 the width of the masseteric plate and the length of the tooth-row 

 are distinctly greater relatively than in the European races. The 

 post-molar length is shorter relatively, and this seems to be due to 

 a shortening of the pterygoid fossse. 



The skull is distinctly larger than in any of the subspecies des- 

 cribed above and the proportional measurements given in Table II 

 sufficiently bring out the many small points of difference between 

 them. 



Local variation : — In his report upon the Kumaon collection 

 (op. cit., p. 296) Mr. Wroughton remarks that " the coloration at 

 several, especially of the higher, stations, is extraordinarily constant
