much more forward than usual. Molars very small in proportion to 

 the size of the animal, their pattern as usual.

 of last foot-pad 17"4. 



Skull. Bregma to tip of nasals 35*0 ; greatest breadth 2 1 '5;

This species is allied to Mus blanfordi, Thos., and Mus con- 

 fiicianus, M.-Edw., but differs from both by its clear grey colour, 

 without any trace of yellow in it, by its shorter tail, forwardly di- 

 rected and paler-coloured incisors, longer palate, and smaller molars.

The collection contains six specimens of this striking new species, 

 which I have much pleasure in dedicating to the donor of the present 

 magnificent addition to the National Collection of mammals. 



General colour above exceedingly like that of Golunda ellioti, Gr., 

 viz. coarsely grizzled grey, lightest on the head and gradually turn- 

 ing to deep rufous on the rump, the tips of the great majority of 

 the hairs being white or yellowish white on the head and fore 

 quarters, and gradually becoming rich rufous on the hind quarters, 

 their bases in all cases deep slaty -blue. The other hairs are black 

 throughout, and form the black element in the general grizzling. 

 Sides like the fore quarters. Belly yellow or orange, mixed with the 

 slate of the hair-bases ; no black-tipped hairs below. The inner 

 sides of the thighs and all round the base of the tail rich rufous. 



The fur throughout is soft, and unmixed with flattened or spinous 

 bristles. 



Feet grizzled yellowish white. Ears thinly covered outside with 

 black hairs, and inside with black and yellow or red ones ; an 

 indistinct tuft of orange-tipped hairs in front of the basal notch. 

 Tail well haired, but not pencilled, markedly bicolor, the hairs black 

 above and white below, but the scales, even of the lower side, are 

 uniformly brown. 



Ears large and evenly rounded, with a small projection in the 

 middle of their inner margins ; laid forward they reach to the pos- 

 terior corner of the eye. Tail about as long as the body without 

 the head. Fifth front toe unusually short, its claw barely reaching 

 to the bottom of the division between the 2nd and 3rd toes, giving 

 the foot, at first sight, the appearance of being only provided with 

 three toes. Fifth hind toe reaching just to the base of the fourth. 

 Foot-pads 5-6. Mammae 8, 2 pectoral and 2 inguinal pairs. 



Skull, both in size and shape, almost identical with that of Golunda 

 ellioti", Gr., with the two following exceptions: — (1) The front
