Tachornis infumata: Grant p. 107; Robinson & Kloss p. 38; Robinson II p. 146. ai 
Collocalia fuciphaga: Williamson I p. 46 (Specimens wrongly identified and ought to be Tachornis infumata). 
I got a single specimen of this species shot out of a large flock a few miles south of 
Koh Lak. Unfortunately the specimen was too badly damaged to be preserved.

Bill: black. Legs: brown. 
Observed and obtained together with Collocalia francica germaini Oust. in the Siam- 
ese Malaya. Here it was rather common though difficult to obtain as the birds always 
were flying at a considerable height. In the North of Siam I never met with it though 
it may occur. Outside Siamese Territory it has been recorded from Tenasserim, 
Southern China, Cochin China, the Malay Peninsula and the Gr. Sunda Islands.

Fairly common and generally distributed among the hill-tracts of Northern Siam. 
They are as a rule assembled in small flocks of about 8 to 10 individuals and were now 
and then seen perching on dead trees. When flying they utter a note remembering of 
that of a Paroquet though it is never very loud. I never saw them keep their long 
crests erect when perching, as has been stated by other observers.
