593 On Siamese and Malayan Birds. [Ibis, 



This has the lateral horseshoe mark quite perceptible. 

 The character is one that is easily obscured in the make-up 

 of the skin, and I do not think it is possible to admit the 

 existence of tvi'o forms of this bird in the Malay Peninsula. 

 The Pnlau Panjani; bird has darker lores than those from 

 Taiping and Ba^an Datch in Perak, but is otherwise 

 identical, Gyldenstolpe's figure is not satisfactory, the 

 yellow of the under surface being too pale, while the black 

 subterniinal band to tiie tail is unduly emphasized. 



-t Anthreptes hypogrammica intensior. 

 Hartert, Bull. B. O. C. xxxviii. 1917, p. 27. 



We have compared a pair from Saribas, Sarawak, with 

 over forty specimens from all parts of the Malay Peninsula, 

 and can just perceive the differences stated by Dr. Hartert, 

 viz., a darker upper surface and yellow richer edges to the 

 feathers of the throat, l)reast, and belly, especially the latter, 

 in the Bornean birds. The differences are, however_, very 

 slight, and we doubt if it would be possible to discriminate 

 with certainty unlabelled birds from the two localities. 



The bird seems rare in Sumatra; we did not obtain it 

 there in 1914, nor is it represented in large collections since 

 received from Padang and Bancoolen on the west coast, 

 and from Deli district in north-eastern Sumatra. It was 

 not obtained by Kloss in Padang, or by Buxton and Forbes 

 in the Lampongs and Bencoolen, though there is, I think, 

 little doubt that it actually occurs in the island. 



-f-Melanoperdix nigra "borneensis. 

 Rothschild, Bull. B. O. C. xxxviii. 1917, p. 3. 

 We cannot detect the very slightest difference between a 

 male from Betong Seribas, Sarawak, collected in August 

 1916, and four males from the low country of Selangor 

 and Negri Sembilan. Our Bornean bird presents not the 

 slightest greenish tinge as stated in Lord Rothschild's 

 description of the type. We have no female Bornean birds 

 for cotnpaiison and have not seen Sumatran birds.
