316 MICROTINJE 



Upper parts dark as in ^. roylei, but rather greyer; under parts 

 silvery grey, darkened by the slaty basal portion of the fur, but 

 without any marked bufiy suffusion ; flank contrast between 

 upper and lower surfaces much sharper than in A. roylei. Tail 

 longer, its length rather more than two-fifths of the head and 

 body measurement, bicoloured, dusky above, whitish below; 

 clothed with short stiff hairs, more numerous than in A. roylei but 

 too few and too short to conceal the annulations completely; 

 terminal pencil very short. Hands and feet essentially as in A. 

 roylei ; creamy white or greyish above. Ears moderate, rounded, 

 and clothed with short hairs similar in colour to the upper parts. 



Skull rather longer, narrower and flatter than in A. roylei, with 

 the braincase noticeably depressed posteriorly. The temporal 

 ridges pursue a slightly less elevated course upon the forepart of 

 the braincase, following the squamoso-parietal suture, so that no 

 substantial portion of each parietal is included in the temporal 

 fossa; post-orbital squamosal crests slightly weaker. Anterior 

 palatal foramina somewhat shorter, ending behind distinctly 

 in advance of the tooth-rows. Bullae considerably larger, trans- 

 versely widened rather than lengthened. 



Dentition somewhat lighter. Enamel of incisors stained a 

 deeper yellow. Cheek-teeth narrower than in A. roylei and not so 

 tall-crowned, the alveolar capsule of m^ making a much less 

 marked protuberance in the mouth of the sphenorbital fissure. 

 Enamel pattern of the teeth essentially similar (Fig. 91, 12). 



For external and cranial measurements, see tables at end of 

 volume. 



Remarks. — Although with the material at present available 

 Bonhote's A. imitator must be treated as a synonym of True's 

 A. montosa, it is not at all unlikely that further work in the field will 

 lead to the recognition of several distinct subspecies in Kashmir. 

 Certain of the skulls before me differ rather markedly from those 

 of the good series of " imitator'' in the collection. It is possible 

 also that intergradation with A. roylei will eventually be proved; 

 but all the specimens from Kashmir at present known have the 

 large bullae and the external characters described above as 

 distinguishing A. montosa from its ally in Kumaon.
