326 W. T. Blanford — On some 3IammaUa from Gilgit. [No. 4«, 



The skull, extracted from tlie skin, is imperfect behind, and the length 



cannot be measured. It was probably under 3^ inches. The following 



are some of the dimensions : 



In. Met. 



Length of suture between nasal bones, 1-23 '031 



Greatest breadth across hinder portion of zygo- 

 matic arches, 1*6 *04 



Breadth of brain case behind glenoid fossa, ... 1-17 '029 



Breadth of frontal region where narrowest be- 

 hind post-orbital processes, 0*57 '014 



Breadth of nasals where widest near posterior 



termination, 062 '016 



„ „ at anterior end, 0'51 '013 



Length of bony palate behind anterior palatal 



orifices, 025 '006 



Width of do. between anterior molars, 0*45 'Oil 



Length of row upper molars, 0'61 '015 



„ of lower jaw from angle to symphysis,.,. 2*25 '057 



Height do. to condyle, 1-32 '033 



The Lagomys I find somewhat difficult to determine. Captain Bid- 

 dulpha has collected two specimens, one from the Gilgit district, obtained 

 at an elevation of 10,000 feet, the other from the Kishengunga valley, 

 at 7500 ft. On the whole these specimens appear to me to agree best with 

 L. auritus, the species inhabiting the Indus valley in Ladak at moderate 

 elevations, but the ears, so far as can be judged, are much smaller, 

 scarcely exceeding in size those of L. Roylei. The dimensions however 

 appear larger than those of L. Roy lei, and the fur is much longer and 

 softer. The colouration of the upper parts is greyish brown, the face 

 being rufous to a variable extent, and there being in both skins a 

 marked rufous patch below the ears, (the glandular patch noticed in 

 skins of some species of Lagomys by Dr. Giinther ; Ann. Mag. Nat. Hist. 

 Septr. 1875, Ser. 4, Vol. XVI, p. 230,) though this is evidently a 

 variable character, for whilst in one skin, and this has the forehead 

 less rufous than the other, the patch below the ear is ferruginous, and 

 the breast, shoulders and flanks rufous, in the other skin the tinge is much 

 fainter and is confined to the sides of the neck. The lower parts are 

 white, faintly tinged with rufous in one specimen, the blackish basal por- 

 tion of the hair shewing conspicuously. 



The skull is very near that of both L. auritus and L. Boylei ; from 

 that of the former it only differs in having the nasals a little broader 

 behind, and the orbits a trifle smaller, and from that of the latter by
