 The males are distinguished from those of other allied 

 species by their small size and by having the abdomen, under 

 tail-coverts, axillaries, and under wing-coveits pure white, the 

 orange of the breast is sharply defined from the white belly, 

 and there is only a very small black chin-spot. 



The female, which has not hitherto been described, has the 

 upper surface bluish grey, bluer on the upper tail-coverts 

 and tail, sides of the head greyish, with a white or buffy- 

 white ring round the eye ; remainder of the under surface, as 

 in the male but the rufous of the breast is duller.

 Birds, ii. p. 25 (1890). 



We have with some doubt referred the four specimens 

 from Kossoom mentioned by Gates loc. cit. and eight more 

 skins from Trang to this species, which can only be regarded 

 as a southern race of C. tickelli. Tlie whole genus, however, 

 is in a very unsatisfactory state and is much in need of 

 revision. The present form is also closely allied to C. suma- 

 trensis, from which it differs in the greater extent of black 

 on the chin and in having the flanks and under tail-coverts 

 tinged with fulvous. 



There is probably a third undescribed species represented in 

 the Trang collection, allied to C. nigrigularis of Borneo and 

 Sumatra, but the material at our disposal is at present not 

 sufficient to justify the bestowal on it of a name.
