A fine series from different parts of Northern and Northwestern Siam. 
One male collected on the 12th of July at Doi Par Sakeng near the Burmese border 
is remarkable for the very dark colouring of the underparts of the body. The breast 
and especially the chest are almost bronzy brown. Even the malar region, the chin and 
the throat are not lemon yellow but »primuline yellow» (RIpaway. Nomel. Col. pl. 16). 
Another male from the same locality is exactly of the same colour. 
specimens have the malar region, the chin and the throat lemon yellow. 
The females collected at Doi Par Sakeng are, however, quite similar to those ob- 
tained at more southern localities and therefore I do not think it wise to split the bird 
into geographical races.
