Bill: black. Legs: black. 
The Ashy Minivet seems to be very rare in Siam and during the whole journey only 
one specimen — in full plumage — was obtained outside Koh Lak. 
A winter visitor only.

The Brown Flycatcher was fairly common in the North of Siam, but it also occurs 
in more southern parts having been recorded from Bangkok by WILLIAMSON and from 
the Malay Peninsula by RoBINsoN. 
This species is generally considered as a winter visitor to South eastern Asia, 
having its breeding places in Eastern Siberia, Corea and Northern China. 
During my journey I obtained specimens in April, May and September which seems 
to indicate that it may possibly breed in Northern Siam too. However, I never found 
its nest. 
As regards size and colour the Siamese specimens are absolutely identical to speci- 
mens from Saghalin in the collections of the Royal Natural History Museum of Stockholm. 
136. Alseonax siamensis. GyLDENSTOLPE.' — The Siamese Brown Flycatcher. 
This new species is related to Alseonax latirostris RaFF.. from which it is, however, 
clearly distinguished by being umber brown (»Saccardos Umber), Ridgway, Plate 39) 
above instead of ashy brown. In several other particulars it also differs from that spe- 
cies, as seen by the description given below. 
Adult male: General colour above »Saccardos Umber» (Ridgway. Nomenel. Colours 
plate 39); upper tail-coverts washed with ferruginous; wing-coverts dusky brown, mar- 
gined with »Saccardos Umber»; primaries and secondaries dusky brown, the latter edged 
with isabelline on the inner webs; tail dusky brown with pale brown shafts; lores and 
a narrow line round the eye greyish white; ear-coverts »Saccardos Umber»; chin and upper 
throat greyish white slightly washed with brown; lower throat, breast and flanks ashy
