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-coverts 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. 
153. CyORNIS DIALILiEMA. 
Cyornis dialilcema Salvad. Ann. Mus. Civ. Gen. xxvii. 
p. 387 (1889). 
Cyornis tickelli (ex Kossoom), Oates, Faun. Brit. Ind., 
Birds, ii. p. 25 (1890). 
We have with some doubt referred the four specimens 
from Kossoom mentioned by Oates loc. cit. and eight more 
skins from Trang to this species, which can only be regarded 
as a southern race of C. tickelli. The 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.
