82 NILS GYLDENSTOLPE, ZOOLOGICAL RESULTS OF THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 



W = 62 mm.; T = 57 mm.; C = 8 mm. — 

 mm.; C = 8 mm. = Irides: blackish brown. 



i Koon Tan 14 /r. 1914. L = 125 mm.; W = 58 mm.; T = 53 

 Bill : horn colour. Legs : brownish yellow. 



The four specimens of the Grey-headed Flycatcher were all collected among the 

 Koon Tan Hills where this species was fairly common. 



A young male shot on the 14th of May 1914 has a plumage very similar to that 

 of the adult bird but the yellow colour of the underparts of the body is, however, very 

 much paler. 



151. Cryptolopha burkii tephrocephalus. Anders. — Anderson's Flycatcher Warbler.

<$ Koon Tan 9 / 9 1914. L = 107 mm.; W = 56 mm.; T = 45 mm.; C = 10 mm.; Tarsus = 15,5 

 mm. — Irides: brown. Bill: upper mandible horn colour, lower mandible yellowish brown. Legs: yellowish brown. 



This species seems to be very rare in Siarn and only two specimens were collected 

 during the whole journey. Both these specimens were obtained among the Koon Tan 

 mountains. It probably breeds in Siarn, because one specimen was shot as late as at 

 the beginning of September 1914. 



152. Abromis superciliaris. Tick. — The Yellow-bellied Flycatcher Warbler.

The Yellow-bellied Flycatcher Warbler was not uncommon in the bamboo-jimgles 

 in the North of Siarn, but it was never met with in the Siamese Malaya. 



Another allied form Abrornis schwaneri Temm. has, however, recently been found 

 by Robinson (Journal Fed. Malay States Mus., Vol. V N:o 3 p. 101, 1915) in Bandon, 

 a Siamese Province in the Malay Peninsula south of the places I visited during my jour- 

 ney. This form is very similar to A. superciliaris Tick. and only differs in having the 

 head and ear-coverts of a darker ashy colour, which abruptly contrasts with the colour 

 of the back. In A. superciliaris the ashy colour is shading off gradually into the colour 

 of the back.
