SCIENTIFIC RESULTS FROM THE MAMMAL SURFEY. 939 



The specimens in Col. Hotson's collection are referable to two 

 species, both new. 



OaLOMYSCUS BALUCHI, Sp. n. 



Size as in C. bailwardi, but with smaller ears. Palatal foramina 

 longer. 



Dimensions about as in bailirardi. General colour very much 

 as in that animal, the intensity of the bnffy somewhat variable. 

 Ears distinctly shorter, usually 18 mm., in two cases 19, while 

 those of the type of G. hailivardi are recorded as 21-5. 



Skull very like that of G. hailwardi, but rather more slenderly 

 built. Palatal foremina uniformly longer. 



Dimejisions of the type : — Head and body, 75 mm. ; tail, 89 

 (ranging up to 96) ; hindfoot, 21 ; ear, 18. 



Skull; greatest length, 26 ; condylo-incisive length, 22-6 

 zygomatic breadth, 12-9; nasals, 9*5; interorbital breadth, 

 4-1; palatilar length, 11; palatal foramina, 5-2; upper molar 

 series, 3*5. 



Hah : — Kelat District, Baluchistan. Type from Kelat itself' 

 other specimens from Harboi, 9,000', in the same neighbourhood- 



T^jje:— Adult s B- M. No. 19. 11. 7. 65. Original number 699. 

 Collected 6th July 1918, and presented by Col. J. E. B. Hotson. 

 Eleven specimens. 



Of the two Baluchistan species this is undoubtedly the closer to 

 G. haihvardi, but may be distinguished by its smaller ears and 

 longer palatine foramina. 



CaLOMYSCUS HOTSONl, sp. n. 



Smaller than hailwardi and haluchi. Colour darker. 



Size less than in the other two species. Fur equally fine and 

 soft. Colour similar in general pattern but decidedly darker, 

 owing to the greater extent of the blackish tips to the hairs, and 

 the rather darker tone of the ochraceous. Undersurface, hands and 

 feet similarly pure white, and tail equally pencilled, tufted, bicolor, 

 blackish above and white below. 



Skull much smaller than in the other species ; interorbital region 

 narrowdr ; palatal foramina of medium length ; bulige rather 

 smaller. 



Dimensions of the type. — Head and body, 72mm; tail, 77; hind- 

 foot, 19 ; ear, 18.
