Very common in jungle from 3,000 to 5,000 feet but 
ceasing abruptly above that level. 
When large series like the present one are examined, the 
Malayan form can only very doubtfully be separated from that 
inhabiting Tenasserim and the Himalayas. The greater 
extent of the white lateral collar, relied on by Sharpe, seems 
largely dependent on age, young birds being much more 
yellow than old ones. Better characters are those given by 
Buttikofer, viz., a constantly longer tail (about 150 against 
135 mm. in Himalayan specimens), quite devoid of any tinge 
of green, even at the base. Differences in the shade of green, 
which have been relied on to separate the specimens from 
Kinabalu, seem to us unimportant. 
The sexual difference pointed out by Whitehead, viz., a 
partially concealed yellow spot on the middle of the nape in 
the female is quite constant in the series of Malayan and 
Sumatran specimens before us, being present in all those 
marked female and absent in all the males. 
Peninsular specimens are practically identical with the 
Sumatran ones; many specimens, however, have a faint blue 
line separating the yellow of the throat from the green of the 
breast, which is present in a smaller proportion of the skins 
from Sumatra and then to a less extent.

“Tris emerald, orbital skin yellowish green; bill robin’s 
egg blue, the basal part chrome yellow, tarsi and feet apple 
green, the terminal phalanges chrome yellow, claws Payne’s 
grey.” (No. 256.) 
This subspecies differs from the Malay Peninsula form 
(Serilophus lunatus vothschildi, Hartert, Bull. B. O. C. vu, p. 1 
(1898)) in the same way as that does from the typical race. 
The general colour of the mantle and the chestnut of the inner 
secondaries and rump is very much richer in tone and the 
colour of the under surface is a darker grey. The greyish 
white of the crown stops somewhat abruptly at the level of 
the eyes and the ear coverts are washed with clay brown as in 
the typical race and not so grey as in S. J. rothschild:. In 
dimensions the present subspecies does not appear to materially 
differ from either of the other races, though the bill is possibly 
slightly smaller. (Types of the subspecies. No. 256, 4: No. 
364, ?).
