It has hitherto been our practice, by reason of the distribu- 

 tions given for H. sibirica and" H. fuligiuosa in the " Handlist of 

 Birds", Vol. iii; p. 204, to record all examples of the Sooty Flycatcher 

 collected in the Malay Peninsula and adjacent islets under Hemiche- 

 lldoiii sihirica fuligiuosa Hodgson. But we have lately re-examined 

 our series of thirt}' specimens and find, with the exception of the 

 two apparently immature birds listed above, and an apparently im- 

 mature individual from Junk Seylon Island with a wing of 71 mm., 

 that the wing lengths of the series range between 75 and 83.5 mm. 

 Apart from the male from Victoria Point and another from Tasan, 

 none of the series has the first primary longer than the wing coverts: 

 in nearly all it is markedly shorter. According to Hartert (Vog. 

 palaarkt. Fauna, p. 479) these birds should be the typical H. s. 

 sibirica — H. s. fuliginosa being a smaller, darker bird with wings of 

 70-75 mm., and the first primary as long or longer than the wing 

 coverts. The three presumably younger specimens are much darker 

 beneath, with less white, tiiau the others : they may possil)ly repre- 

 sent H. 6". fidigiiiosa. Nearly all our specimens come from islets in 

 the Straits of Malacca or the mountains of the Malay States and all 

 were taken between November and April.
