114 Mr. R. B. Sliarpe on the Genus Orthotomus. 



the genus Orthotomus by its grey head and pure white ear- 

 coverts. 



6. Orthotomus castaneiceps. 



Hah. Guimaras and Panay, Philippine Islands. 



This distinct species was described by Lord Tweeddale 

 (Walden, Ann. Nat. Hist. ser. 4, x. p. 252, et Tr. Z. S. ix. 

 p. 195) from the island of Guimaras ; and Dr. Steere obtained 

 another, which agrees exactly with the type kindly lent me 

 by Lord Tweeddale, in the neighbouring island o£ Panay. 



7. Orthotomus derbianus. 

 Hab. Philippine Islands. 



Specimens of this bird are in the Derby Museum at Liver- 

 pool {cf. Moore, P. Z. S. 1854, p. 309, pi. Ixxvi. descr. orig.) 

 and in the British Museum ; but the exact island inhabited by 

 the species has not been determined ; it will probably be found 

 to be Luzon. 



8. Orthotomus ruficeps. 



Hab. Malacca, Sumatra, Borneo, and Palawan. 



From Malacca we have in the British Museum two speci- 

 uiens — one presented by Captain Stackhouse Pinwell, and the 

 other procured by Mr. Wallace. A specimen from Sumatra 

 is also in the national collection. Two specimens were also 

 sent by Mr. Hugh Low in a recent collection made by him 

 in North-wester-n Borneo, opposite the island of Labuan. 

 Doria and Beccari met with it at Sarawak (Salvad. Ucc. Born, 

 p. 249). Dr. Steere likewise obtained a specimen in the 

 island of Palawan, Philippines. 



9. Orthotomus cineraceus. 



Hab. Malacca, Sumatra, and Borneo. 



Fron- an examination of a very large series recently brought 

 from North-western Borneo and Labuan by Mr. Hugh Low, 

 I am able to affirm that 0. borneonensis of Salvadori (Ucc. 

 Born. p. 247) is the fully adult male of O. cineraceus, Blyth 

 (J. A, S. B. xiv. p. 489). It appears to be a common bird 

 in Borneo, as it has been obtained not only in the above- 

 mentioned localities, but at Sarawak by Doria and Beccari,
