Should this prove to be really so, it will be a most interesting fact, for 

 hitherto in these Reports I have adopted a working theory that the white 

 bellied form is a truly wild form, while true rufescen is the result of iDara- 

 sitism on man, living in pucca houses, and therefore as rufescens, it would be 

 hard to account for their presence in the Chin Hills.

 This specimen is conspecific with Mr. Shortridge's series from Hkamti, 

 which was classed in the Chindwin Report as jerdoni. Since then the 

 \\&m.& jerdoni has had to be abandoned {vide Sikkim Report), as a synonym 

 of fidvescens, consequently another name has been provided by Mr. 

 Thomas.

 "Fairly common in the jungle. I have never obtained it from the fields. 

 The Chins say that, about February-March, 8 or 9 young ones are found 

 with an old female (very rarely an old male) in a single hole ; later they 

 break up and pair. Old males are said to live alone except when 

 paired."— J. M.D.M.
