590 Messrs. Robinson and Kloss on recently [Ibis, 



northern Siara, and Doi Nga Chang, Lampang, northern 

 Siam, 4500', which we owe to the kindness of Mr. William- 

 son, and which we regard as representative of P. o. ripponi 

 Hariiigton (Bull. B. O. C. xxvii. 1910, p. 9) of the Shan 

 States. 



These differ from P. o. fastidiosus in being generally 

 lighter above without a markedly greyisli-black cap, the 

 patches in the sides o£ the neck more ochraceous orange, 

 less chestnut, and more diffused into the nape. Tail decidedly 

 less dark, especially at the base. 



These are the characters which are stated to characterize 

 P. 0. siamensis, which must therefore be suppressed. 



' Cyanoderma erythropterum sordida. 

 Stuart Baker, Bull. B. O. C. xxxviii. 1917, p. 10. 



We possess a large series of this subspecies from all parts 

 of the peninsula from Bandon in peninsular Siam to Gunong 

 Angsi in Negri Sembilan. 



Those from Bandon and Trang, within 150 miles of 

 Maprit, the type-locality of 6'. e. sordida, arc certainly quite 

 inseparable from the most southern specimens. It is un- 

 doubtedly the case that the black of the throat, and indeed 

 the whole plumage, fades with considerable rapidity in the 

 skin, as is the case with a very large number of Timeliine 

 birds. Mr. Stuart Baker has evidently been misled by 

 freshly collected skins, and his subspecies cannot be main- 

 tained. Freshly collected birds from Pulau Tioman present 

 the same differences. 



4^ Tchitrea paradisi borneensis. 

 Hartert, Bull. B. O. C. xxxvi. 1916, p. 75. 

 We have in our collection four adult males of this race 

 with the tail fully developed. The tails of all greaily exceed 

 those of any specimen of T. p. affinis in our collection, but 

 do not attain the length of 459 mm. given for the type, the 

 largest being 375 mm. The bills are certainly markedly 

 larger than those of the vast majority of 1\ p. affinis, though 

 one specimen from Traug, peninsular Siam, is as large as 

 any of the Bornean birds in this respect.
