III. — Descy'iption of a new Species of Mus from Southern 

 India. By Oldfield Thomas, F.Z»S., British Museum. 



The specimen here described was obtained at Kadapa, Madras, 

 by Colonel K. H. Beddome, and has been presented to the 

 British Museum, together with a large series of other Indian 

 Muridffi, by Mr. W. T. Blanford, after whom I propose to 

 name it 



Mus Blanfordiy sp. n. 



Fur above slate-colour, tipped with fawn j hairs rather long 

 and soft. Belly white, sharply defined. Tail longer than 

 head and body ; basal half dark, distal half above and below 

 white; distal third covered with soft, white, shining hairs 

 about a quarter of an inch long, forming a pencil at the tip. 

 Tarsus rather long. Five front and six hind foot-pads. 

 Ears long, oval, nearly naked. Mammse six, one pectoral and 

 two inguinal pairs. 



The skull differs from those of all other Indian rats by 

 the front edge of the external wall of the infraorbital fora- 

 men being strongly slanting instead of perpendicular. The 

 interparietal also is much more elongated transversely than 

 usual. 



Measurements of the type, an adult female r — Head and 

 body (about) 4"1 inches ; tail 6*1 ; hind foot, without claws, 

 1'2 ; forearm and hand 1'3 ; ear-concb, length from external
