 or else a warmer reddish-brown. Under parts whitish. Feet 

 white. Tail more or less distinctly bicoloured. Palmar tubercles 

 5, plantar tubercles 6 ; soles clad rather densely with stiff white 

 hairs behind the pads; claws as in A. roylei. Mammas 2 — 2 = 8. 

 Skull rather long and narrow, delicately built with moderately 

 developed or rather large auditory bullae. Dentition (Fig. 

 91,8, 13, 2o) as in other members of the roylei group ; m^

Co-types.— Two in British Museum (Nos. 81.3.1.22 and 8.3.9.17) 

 and two in the Indian Museum, Calcutta (Nos. a and b). Of 

 these Thomas has selected B.M., No. 8.3.9.17, an adult male, skin 

 and skull, as the " lectotype " (J. Bombay N.H.S., 25, 1918, 

 p. 371). 



Type locality. — Gilgit, at altitudes between 9000 and 10,000 

 feet. 



Range. — At present known only from the vicinity of the typ 

 locality. 



Characters. — Upper parts rather light greyish-brown, with a 

 very slight rufous tinge ; under parts greyish-white darkened by 

 the slaty hair bases; no sharp line of demarcation along the 

 flanks. Feet white. Tail brown above, dirty white below, its 

 terminal pencil about 5 mm. long. 



Skull long, narrow, and depressed, with a slender rostrum and 

 moderately large auditory bullae ; characters not fully appreciable 

 from the available material. Distinguished from that of the 

 next subspecies by its longer and relatively narrower nasals and 

 rather larger bullae. Dentition (Fig. 91, 8, 20) : m^ with the fourth 

 outer angle represented usually by a vestige.

 volume.
