All the specimens listed here can safely be referred to the 

 Indo-Chinese race of the Blue Flycatcher : but specimens from Patani 

 and other parts of the south sho^Y gradation towards the Malaysian 

 form, H. a. jyt'ophata Oberholser (type locality, Kerimun Id., near 

 Singapore), in which the white of the abdomen is reduced in area 

 and less pure in colour. These intermediate Patani birds might 

 equally well be called H. a. x>ropliata. 



329. Rhipidura albicollis (Vieill). 



Platyrhynchus albicollis, Vieill., Nouv, Diet. d'Hist. Nat. xxvii, 

 1818, p. 13 (Bengal). 



We have specimens from Khao Luang, 4,300 ft., Peninsular 



Siam, collected in March 1922, which are perhaps scarcely so grey as 



the typical bird, thus showing some approach to atrata Salvad., of 



Sumatra. 



330. Rhipidura aureola burmanica ( Hume ). 



Leucocerca burmanica, Hume, Stray Feathers, ix, 1880, p. 175, 



footnote (Thoungyeen Valle}'). 

 Rhipidura albifrontata burmanica, I., p. 80 (Koli Lak). 



Gyldenstolpe's record from Koh Lak is the only one for the 



area. 



331. Rhipidura javanica javanica (Sparrm.).
