I 



ALTICOLA 315 



closely with the accounts of the type of A. alhicauda published 

 by True and Miller. 



Skull, judging from the measurements and figures given by 

 Miller, with the zygomatic breadth relatively greater than in 

 A. hla»fordi; about as in A. roylei; auditory buUsc considerably 

 larger than in the latter, larger even than in A. worthingtoni 

 according to Miller. The skulls from Nahr Nullah before me 

 are defective; but in them the rostral and palatal portions are 

 as in A. blanfordi, the nasals being, however, rather shorter and 

 I broader. 



I Cheek-teeth characterized by the somewhat peculiar form of 



\ m^. In this tooth (Fig. 91, u and fig. 4a, Miller, 1899) there are 



! three outer and three inner salient angles ; the third outer infold 



is so reduced that the third triangle is rather broadly confluent 



with the somewhat shortened posterior loop, instead of being 



' substantially shut off from the latter as is usual in most other 



species of Alticola. In this respect it agrees with A. roylei in 



which, however, the posterior portion of the tooth is less reduced. 



For external and cranial measurements see tables at end of 



volume. 



; Remarhs. — Only four specimens of this vole are at present 



known, viz., the type from the Braldu Valley and three examples 



' in the British Museum collected by Mr. C. H. T. Whitehead in 



1 the Nahr Nullah, Skardu. One of the latter (B.M., No. 5.10.8.5), 



i a male, is of interest, since it shows the beginning of the autumn 



moult; on parting the hairs over the rump the pale tips of the 



developing winter coat are seen rising up among the slaty bases 



of the summer hairs. The slight differences in colour which appear 



to exist between these Skardu specimens and the type of A. 



alhicauda are not improbably seasonal.
