and tlie crown vinaceous buff. Under surface pale yellowish 

 white, not sharply defined laterally, yellower on the throat 

 and belly, becoming gradually whiter on the chin and under- 

 sides of limb?!, but without the marked contrast between a 

 pure white chin and a strongly yellow or buffy thront. 

 Palms and soles with an intermediate state of hairiness 

 between that found in altaica and. longstaffi,^ the ends of the 

 digits and the median pad exposed, but less so than in long- 

 stoffi, and the proximal carpal pad — prominently open in the 

 latter species — quite hidden in the fur. 



Skull and teeth about as in altaica, though the inner edge 

 and antero-internal corner of the bullae are less angularly 

 prominent. 



Dimensions of the type (measured on the skin, and there- 

 fore only approximate) : — 



Head and body 280 mm. ; tail 180 ; hind foot 45. 



Skull: basal length 48'5 ; greatest breadth 28*5; inter- 

 orbital breadth 11*5; intertemporal breadth 10'2 ; mastoid 

 breadth 24 ; palatal length 23'7 ; maxillary tooth-row 16*3 ; 

 p^ 6 ; 7w', transverse diameter 4*3, breadth of inner lobe 2'4. 



Type. A'lult male. B.M. no. 14. 5. 10. 64. Original num-

This fine weasel is intermediate in character.-, as in locality, 

 between M. altaica of the Altai and M. longstaffii of the 

 Upper Sutlej and Ladak ; and it is possible that hereafter all 

 three may be considered as subspecies of one widely spread 

 species. The marked diflferences in the degree of hairiness 

 of the feet, however, prevent my adopting this course without 

 further intergrading material. Apart from the feet, M. sacana 

 may be distinguished from altaica by the absence of contrast 

 in the colour of the chin and throat, from longstaffi by its 

 more yellowish belly, not defined laterally, and from M. temon 

 by its larger size.

Two males in winter pelage. 



Barrett-Hamilton's type of pallida being a female, and 

 both the present specimens being males in winter pelage, it is 

 impossible to express any definite opinion as to the latter's 

 relationship to pallida or to Blanford's stoliczJcana, of which 

 the figured skull is, however, larger than those of Mr, 

 Riickbei^s two males.

 Four male^', one in sumuier, one in changing, and two in 

 winter pelage.
