80 NILS GYLDENSTOLPE, ZOOLOGICAL RESULTS OF THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 
prophata is said to occur. However, the two races seem to be only slightly differentiated 
from each other, the first one only being characterized by its distinct bluish not lilac back. 
However, all the specimens from Northern Siam have a distinctly violet shade on 
the back and it is with great hesitation that I accept these two races, but for the present 
I think it is wise to do so. In any way the specimens from Lower Siam and the Malay 
Peninsula are almost identical.

Fairly common in Northern Siam among the Koon Tan Hills most often in com- 
pany with other species of Flycatchers. It was always observed in very dense forests 
and as a rule far away from villages or human dwellings. 
The two specimens procured are not fully adult but showing traces of the immature 
plumage in having a rufous shade on the underparts of the body and in having marked 
rufescent tips to the wing-coverts and some of the feathers on the back and rump. 
The birds obtained in Siam may possibly belong to R. a. atrata Satvav. from the 
Malay Peninsula and Sumatra. This rase is chiefly characterized in having more ex- 
tended white tips to the tail-feathers. As I have no material for comparison I have re- 
frained from giving the Siamese birds a subspecific name.

The Java Fantail Flycatcher was never obtained in the Northern and Central parts 
of the country, but it was exceedingly common down in the Siamese Malaya. It was most 
often found in dense bamboo-jungle, where it keeps to the lower branches jumping 
about in search of food or uttering their faint trilling note while it keeps its tail spread out 
and its wings half open. It is also often seen on the ground behaving in the same manner.

Fantail Flycatcher.

Two specimens of this bird, which has not been recorded from Siam before, were 
observed in a thick and thorny bamboo-jungle near the coast at Koh Lak during one of 
my excursions on the 26th of November 1914. The birds were in company with Rhipi-
