16 MR. RAMSAY ON THE ORNITHOLOGY OF SUMATRA. [Jan. 6, 



rufous-brown, shading into bright chestnut on the hinder part, and 

 widening into a broad patch on either side of the neck. 



Length about 7'^ inches, wing 3*6, bill -QS, tarsus 1*25. 



One specimen only of this new species is in the collection. 



Myiophoneus castaneus, sp. n. (Plate I.) 



Bright chestnut-brown, except on the head, face, throat, and 

 breast, which are dull purplish blue, and the forehead and lesser 

 wing-coverts bright cobalt. 



Mount Sago, 3 September, 1878. Iris grey-blue (Bock). 



In the British Museum I found an example of this bird, labelled 

 " Malacca," but without a name. The locality is probably erroneous. 

 This specimen differs considerably from mine, both in dimensions and 

 colour, the purphsh-blue head being overlaid with a tinge of chestnut, 

 and the lores and forehead being dusky chestnut-brown. 



The dimensions of the two specimens are — 



Of the 24 species described as new by Count Salvadori (I.e.), 

 only 8 were obtained by Mr. Bock, viz. : — 



Chrysophlegma mystacalis. Pteruthius canieranoi. 



Rhipidura atrata. Myiophoneus dicrorhynchus, 



Hemipus iniermedius. Arrenga nielanura. 



Heterophasia simillima, Peloperdix rubrirostris. 



Two of these I cannot admit as good species — Hemipus inter- 

 medins and Pteruthius cameranoi. The former, of which I have 

 one good specimen, appears to me to be inseparable from examples 

 in the British Museum of Hemipus picatus (Sykes), collected at 

 Mahabaleshwar. The latter I have compared with a specimen in 

 the same museum of P. eeralatus, Tickell, from the Kachyen hills 

 in Western Yunnan, and found to be identical. 



Yet another of the species contained in the above list is, I should 

 say, of somewhat doubtful validity. Rhipidura atrata is very close 

 to, if not identical with R. albicollis (Vieill.) = jR. fusciventris 

 (Franklin), of India. It differs, no doubt, in the shade of slaty black 

 of its plumage; but I have found specimens in the British Museum of 

 R. albicollis which nearly match the Sumatran examples, although 

 I am bound to say not quite. The difference, however, is so very 

 trifling that the Sumatran bird can, I think, be hardly regarded as 

 belonging to a distinct species.
