the genus Orthotomus by its grey head and pure white ear- 
coverts. 
6. Orthotomus castaneiceps. 
Hab. 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 of 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. lxxvi. 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. 
Prom Malacca we have in the British Museum two speci¬ 
mens—one presented by Captain Stackhouse Pin well, 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-western 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. 
From 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 O. 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,
