SUMMARY OF THE INDIAN MAMMAL SURVEY. 787 



Gen. II. — GuNOMYS. 



Thomas established this genus to represent the southern or 

 long-tailed mole-rats (A. M. N. H. (7), xx., p. 203, 1907.) 



In my paper quoted above, I 

 No. 29io.bengalensis, Gf. &i accepted eight species which were 

 H. recorded to occur within our area. 



Additional material however shows that the separation of tora?/ewsis, 

 Horsf. from bengalensis, cannot be maintained, consequently as the 

 later name the former mu§t rank as a synonym of the latter. The 

 remaining seven may be arranged in a key as follows : —
