less fossorial type than those of Gunomys, as indicated by the longer 

 nasals and normally set incisors (angle with molar tooth row 80°— 

 90°*) as compared with the shortened nasals and forwardly projected 

 incisors (angle over 95°) of the latter genns. In these respects, as 

 also in its parasitic habits, B. savilei is absolutely a Bandicota, and 

 does not show any real approach to the other gentis. 



The species is named after Mr. L. H. Savile, who was Honorar}- 

 Treasm-er of the Bombay Natural History Society for many years, 

 and has taken great interest in the success of the Mammal Survey. 



Passing to the B. nemorivaga group I may recoi'd that the British 

 Museum contains examples referable to nemorivaga itself from 

 Nepal (Hodgson and Manners-Smith), Calcatta (Blanford and 

 Indian Museum), Khasia Hills (Blanford), Toungoo (Oates), 

 Tengyueh, Western Yunnan (Howell), Southern Yunnan (Orii) and 

 Formosa (Swinhoe). 



With regard to the last named, Swinhoe suggested that the 

 animal had probably been introduced artificially into the island, a 

 suggestion supported by Mr. Wroughton, who has considerable 

 knowledge of the way these animals are carried about in the Chinese 

 rice boats, and also by nyj entire failure to find the slightest 

 difference between the Formosan and Burmese specimens, great as 

 is the geographical gap between them. 



But the form found in Siam seems distinguishable and may be- 

 called 



Bandicota mordax, sp. n. 



Near B. nemorivaga but with larger teeth. 



Size about as in B. nemorivaga, or, since the type is not full 

 grown, perhaps averaging larger. Ftir of the posterior ' back more 

 profusely mixed with long blackish bristles, so that the colour is 

 consequently darker than in nemorivaga. and the general appearance 

 is more like that found in the gigantea group. Undersurface slaty 

 grey, less broadly washed with whitish than in nemorivaga. Hands 

 brown with whitish digits, feet wholly brown. 



Skull apparently quite as in nemorivaga ; supraorbital ridges not 

 yet so developed in the type ; palatal foramina narrowed posteriorlj-. 



Molars large and heavy, their breadth markedly greater than in 

 the allied species. 



Dimensions of the type, measured in the flesh by Mr. Lyle : — 

 Head and body 228 mm. ; t^il 230 ; hindfoot 52 ; ear 31. Skull :— 

 Condylo-incisive length 55-3; zygomatic breadth 30; nasals 

 21x6-8; interorbital breadth 7-4; breadth between ridges on
