Gen, I. — Bandicota. 



Blanford uses Nesocia (as he spelt it) for all this group, but 

 Thomas restricted the name to the extreme northern and western 

 forms, and at the same time revived the genus Bandicota and 

 established Gunomys (A. M. N. H. (I), xx., p. 202, 1907). 



In a paper in this Journal (J. 



B. N. H. S. xviii., p. 748, 1908) 



I discussed this group, and recog- 



No. 296. bandicota, Bechs. nised five species (using indica, 



No. 297. nemorivaga,ii-odgs. Bechstein for bandicota, Bechstein, 



as being the earlier of the two 

 names), and Thomas has recently added another, viz. : — savilei (J. B. 

 N. H. S. xxiv., p. 641, 1916). These six species may be arranged in 

 a key as follows : —
