EXPLANATION OF PLATE II. 



Fig. I. — Seven adult specimens of Nesokia from the Amritsar dis- 

 trict showing the gradation and amount of variation in 

 size. They probably represent two separate races, for 

 the smallest ones seemed to be segregated near the vil- 

 lage of Atari. The isolated specimen on the right is an 

 average member of the Quetta race of Nesokia ; it is 

 somewhat larger and has a shorter tail than the 

 Amritsar race. 



Fig. 2. — Skulls of the same seven specimens. It can be seen in 

 three skulls that the last molar tooth is well worn ; all 

 seven are in this condition ; their maturity cannot be 

 questioned. Apart from the difference in size, there 

 are noticeable differences in form. In the skull marked 

 P. C. M. 2 the supratemporal ridges are more conspicu- 

 ous and much more adjacent than in S. B. B. i8. These 

 differences are characteristic of the larger and smaller 

 types respectively.
