IXULUS FLAVICOLLIS HARTERTI, Subsp. n. 



Adult. Similar to /. jiavicollis Hodgson from Nepal, but 

 differs in having the crest of a darker and richer brown ; 

 the collar of a deeper and brighter chestnut ; and the 

 back of a much darker olive-brown. In /. jiavicollis the 

 collar is pale rufous. 



Hab. The Bhamo Hills and Trans-Salween Shan States, 

 Burma. 



Type in the Tring Museum : No, 232. ? . Sinlum, Bhiamo, 

 25.iv.08. H. H. Harington coll. 



Obs. Birds from Assam are almost identical with examples 

 from Burma ; those from the Chin Hills (Mt. Victoria) 

 approach nearer to I. Jiavicollis from Sikkim. 



Siva cyanuroptera oatesi, subsp. n. 



In the British Museum there are three specimens of a 

 Siva collected by the late E. W. Oates, on Byingyi, an 

 isolated hill of 6200 feet, situated on the edge of the 

 Shan Plateau (' Ibis/ 1894, p. 481). 



These three birds are quite distinct from S. sordida Hume 

 from Tenasserim, of which there is only one specimen, 

 the type, in the British Museum. The other specimen, from 

 Karennee, which has been referred to this species, differs in 

 the colour of its head. 



Adult. Intermediate between S. c. ivingatei O.-Grant from 

 Yunnan and S. c. sordida Hume from Tenasserim. It re- 

 sembles the former in the colour of its back and upper 

 plumage in general, being of an olive-brown tinged with 

 ochraceous on the rump, but differs from that species in 

 having the head almost entirely dull blue, showing only 

 faint indications of stripes, which are so conspicuous in S. c. 

 ivingatei. It resembles S. c. sordida in the colour of its 

 under-plumage, which is white, while in S. c. ivingatei these 

 parts are pale grey with a vinous tinge. 



Hab. Byingyi Mountain. 



Type in the British Museum : Adult. Mt. Byingyi, iii. 94.
