NESOKIA BENGALENSIS. 



The following table shows the variations in size and the pro- 

 portionate measurements of Nesokia bcngalensis as found in Dacca. 

 In this case also, judging by the breast development, it appears 

 that maturity is reached when the rat is 14 cm. in length. Of 28 

 female specimens under 14 cm. none have developed breasts. 



The adult N. bcngalensis measures anything from 14 cm. to 

 21 cm. 



Bristles appear in the fur of adults at all stages. 



Colour. — The colour is iron grey or greyish brown. 



Tail. — The tail is from 75 — 80 per cent of the length of the 

 head and body, though it may be shorter in old specimens. 



Hind foot. — The hind foot shows a regular gradation of propor- 

 tionate measurements with the increase of age. The sole is purple 

 throughout. The pads number five fully developed ones, and one 

 (the proximo-external) which is rudimentary. In 9 per cent, of 56 

 N. bcngalensis examined with special care, the proximo-external 

 pad was absent. The median pads are frequently cordiform though 

 smaller than in M. rattus.
