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 Siarn ha ve 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 Siarn and the Malay 

 Peninsula are almost identical. 



146. Rhipidura albicollis. Vieill. — The White-throated Fantail Flycatcher. 



c? Koon Tan 24 /r, 1914. L = 170 mm.; W = 76 mm.; T = 101 mm.; C = 10 mm.; Tarsus = 16 mm. 

 J Koon Tan 3 % 1914. L = 182 mm.; W = 77 mm.; T = 102; C = 10 mm.; Tarsus = 17 mm. — Irides: 

 black. Bill: black. Legs: dark brown. 



Fairly common in Northern Siarn among the Koon Tan Hills most of ten 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 Siarn may possibly belong to B. a. atrata Sal vad. from the 

 Malay Peninsula and Sumatra. This rase is chiefly characterized in having more ex- 

 tended white tips to the tail-feathers. As I ha ve no material for comparison I have re- 

 frained from giving the Siamese birds a subspecific name. 



147. Rhipidura javanica. Sparrm. — The Java Fantail Flycatcher.

$ Kob Lak 21 /u 1914. L = 176 mm.; W = 72 mm.; T = 95 mm. — <j> Koh Lak - >7 /ii 1914. 

 L = 170 mm.; W = 72 mm.; T = 93 mm. — J Koh Lak 28 /n 1914. L = 175 mm.; W = 75 mm.; T = 

 97 mm. — <$ Koh Lak 27 /n 1914. L = 180 mm.; W = 81 mm.; T = 103 mm. — Irides: blackish brown. 

 Bill: black. Legs: black. 



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. 



148. Rhipidura albifrontata burmanica. Hume. — The Burmese White-browed 



Fantail Flycatcher. 



$ Koh Lak M /u 1914. L == 168 mm.; W = 83 mm.; T == 98 mm.; C — 11 mm.; Tarsus **= 16 mm. 

 — Irides: blackish brown. Bill: black. Legs: black. 



Two specimens of this bird, which has not been recorded from Siarn 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-
