 collectors. 



Obs. I have for some time hesitated to describe this bird, 

 but it is certainly new, as it differs in coloration from 

 T. indicus indicus (Vieill.) in having the underparts greenish- 

 brown (instead of orange), the head olive-coloured. I had 

 a suspicion that it might prove to be an example of the 

 latter in immature plumage, but this cannot be the case. 

 The wings and tail are shorter, the former much less pointed, 

 the tip (i. e., the distance between the secondaries and the 

 tips of the primaries) measuring barely 15 mm., as compared 

 with 18 to 20 mm. in T. i. indicus; the fourth primary quill 

 is, moreover, slightly longer. 



The bird supposed to be the female of this species differs 

 from that of T. i. indicus in being less yellowish both above 

 and below, while it differs from the female of T. juhnstonice 

 (Grant) in having yellowish (instead of white) under tail- 

 coverts, yellower (less greyish) under wing-coverts, and wider 

 white tips to the feathers of the supercilium, a character 

 which is also seen in the male of T.johnstonice.
