The variation in the degree of vaulting of the skull makes me now 

 rather doubtful whether S. irene of Szechwan should have been 

 separated from S. macrurus.

 ( d Mogok, Upper Burma, 4,400'. 12 June 1906. Collected 

 and presented by H. Hampton, Esq. B. M. No. 6. 8. 

 12. 1.) 



Nearly related to M. suhJiemachalana, but larger. 



General characters very much as in subhemachalana, the dull 

 fulvous upper colour (between " cinnamon brown " and " sayal 

 brown " of Ridgway), the scarcely lighter lower colour, the whitish 

 chin, and the cylindrical, black-tufted tail all as in that animal. But 

 the size, as may be seen by the skull measurements below, is so mate- 

 rially larger that the two forms can certainly not be considered the 

 same, whUe the tail is also longer and its black tuft better developed. 



Skull as in subhemachalana, but much larger. 



Dimensions of the type, succeeded, in parentheses, in the case of 

 the skull by those of a rather younger, but fully grown, male of sub- 

 hemachalana : — 



Head and body 304mm ; tail 172, hindfoot 55, ear 29. 



Skull, greatest length 61.5 (54.3), condylo-basal length 61.5 (53.5), 

 zygomatic breadth 30 (26.3), interorbital breadth 12.7 (11), mastoid 

 breadth 28.3 (23), palatal length 28.5 (24), length of bulla 17 (15), 

 front of canine to back of M^ 18.2 (15.4), carnassial, length on outer 

 side 6.8 (6), M^ 5 (4.7) x 3.5 (3). 



Hab. of type Imaw Bum, Lat. 26—10'. Long 98—30'. Alt. 9,000'. 

 Another specimen from Mogok, Upper Burma. 



Type:— Adult male. B. M. No. 20. 8. 7. 5. Original number 27. 

 Collected 29th October 1919 by F. Kingdon Ward. Presented by the 

 Bombay Natural History Society. 



This fine stoat is clearly distinguished from M. subhemachalana 

 by its greater size, and from all the forms of the M. sibirica group 

 by its black-tipped tail. 



An old male of it in summer pelage was presented to us in 1906 

 by Mr. H. Hampton from Mogok, but was not distinguished from 

 M. subhemachalana until now. As a specimen it is not so suitable 

 to be made the type as that sent by Mr. Ward, but Mr. Hampton 

 should be recognised as the first discoverer of the species.
