The averages of 33 (H. &B. 130 to 1 79) from all localities are :— 



148_202— 31— 22^6=100— 136^5— 21— 15-3. 

 The averages of 15 (H. & B. 130 to 179) from Hoshangabad 

 and Barighat : — 



147— 191— 31-2— 231=100— 130— 2b2— 15-7. 

 The averages of 5 (H. & B. 136 to 158) from Chickpalli are : — 



145— 221— 31-2- 22-2=100— 152— 2r6— 15^3. 

 The variation of proportions with increasing body length is 

 shown below. The relative tail length exhibits much irregularity 

 .when the 33 specimens are treated as a whole ; but this irregularity 

 is> to some extent, diminished by keeping the rats from Hoshan- 

 .gabad apart from those from Chanda. Although short-tailed rats 

 appear to l)e more freqiient in the former district and long-tailed
