30 GYLDENSTOLPE, BIRDS COLLECTED BY THE SWEDISH ZOOLOGICAL EXPEDITION TO SIAM. 



Chai. The Bangkok specimen, sliot on the 18tli of December 1911 has the feathers 

 on the crown of a brownish colour and I sent this specimen to Mr. W. R. Ogilvie 

 Grant for hearing his opinion. He believed that the crownfeathers had been 

 discoloured perhaps by the carbohc acid, but I don't think that this is possible be- 

 cause I beheve to remember that the specimen already had this brownish coloured 

 feathers when it was shot. But in every other part it agrees perfectly well with 

 the description of Phylloscopus swperciliosa Gm. Also the measures correspond with 

 those of the Crowned Willow-warbler as seen below.

38. Cryptolopha burkii tephrocephalus Anders. — Of Anderson's Flycatcher 

 Warbler I only got a fine male specimen shot near a small creek at Kao Plyng on 

 the 27th of January. The creek was quite surrounded by a dense vegetation which 

 made the progress very difficult and very unpleasant owing to the immense num- 

 bers of leeches living among the vegetation. The birds were two in company and 

 in any other part of the country I did never observe nor collect any more speci- 

 mens of this fine bird, which inhabits Burma, Pegu, Tenasserim and the Shan States 

 as far as the mountains of Szetchuan. 



Length -- 102 mm.

39. Abrornis superciliaris Tick. — When making an excursion along the Meh 

 Lem river in Northern Siam I also got among some other fine birds a male spe- 

 cimen of the Yellow-bellied Flycatcher-warbler and this was the only time I observed 

 this bird in Siam. The wing is 44 mm. and the tail is 37 mm. and both these 

 measures do not agree well with the measurements given in the litterature for 

 Abrornis superciliars Tick. but in every thing else it resembles the descriptions. 



40. Prinia blanfordi \V' ald. — The Burmese Wren Warbler was collected in 

 the brushwood and secondary jungles near Pak Pan, and in these places it was not 

 at all rare. Close to the village of Sakerat I also observed some birds probably being 

 Prinia blanfordi Wald. but as I did not get any specimens from tliere I can not 

 make sure if they belonged to this or another species of Prinia. 



My specimens do not agree quite well with the descriptions given both in 'Cata- 

 logue of Birds ' and in Blanford's Fauna of British India» as seen by the follow- 

 ing notes. There is no tinge of green running through the upper plumage which 

 is earthy brown, thus resembling Prinia inornata Sykes. and there are no dark cen- 

 tres on the feathers on the back. The subterminal black patches on the tail-feathers 

 are not so broad as the feathers and the lores are white and the ear-coverts greyisli
