32o APPENDIX. 



b. [young]. Geruah, January 25, 1875. Iris hazel ; bill and legs 

 black. 



c. [adult]. Not labelled. 



[Similis B. pallido sed cineraceus ; gula conspicue alba ; pectore 

 et corporis lateribus pallide cinerascentibus ; subcaudalibus albis. 



Adult male. — General colour above ashy ; the head slightly 

 browner, with indistinct brown shaft-streaks ; least and median wing- 

 coverts like the back ; the median and greater coverts brown, edged 

 with ashy brown, a little reddish on some of the outer greater coverts ; 

 quills brown, externally ashy or fulvous brown, the primaries and some 

 of the innermost secondaries edged with pale whity brown ; tail- 

 feathers ashy brown, the feathers edged with paler brown ; lores and 

 a small patch above and below the eye dull white ; in front of the eye 

 a dusky spot ; ear-coverts brown, slightly washed with fawn-colour, 

 and contrasting with the ashy grey head ; cheeks ashy grey, like the 

 sides of the neck ; entire throat white, strongly defined ; remainder 

 of under surface pale ashy brown ; whitish on the lower abdomen, vent, 

 and under tail-coverts ; under wing-coverts and axillaries pale ashy like 

 the breast, the lower coverts slightly tinged with fawn-colour ; quills 

 dusky brown below, pale ashy fulvous along the inner web. Total 

 length 7 - 5 inches, culmen 0-55, wing 3-85, tail 3*1, tarsus 0*85. 



After a careful comparison of specimens I came to the conclusion, 

 as stated in the first edition of the present work, that this bird was 

 new to science. At first I thought it would be B. nncrinus (Finsch 

 and Hartl.), but the ear-coverts in that species are described as being 

 like the sides of the neck and crop, whereas here the ear-coverts are 

 in strong contrast ; the under wing-coverts also are not fawn-colour in 

 Mr. Oates's specimens. Having compared it with all the other species 

 of Bradyomis represented in the British Museum, I modify the ' Key 

 to the Species,' given in the British Museum ' Catalogue of Birds,' 

 vol. iii., p. 308, as follows : — 



a. Upper surface ashy or clear brown, not black. 



a'. Above light reddish brown, uniform ; throat white, like the 



rest of the under surface ; under wing-coverts white. — Mariquensis. 

 b'. Above ashy ; throat white, contrasting with the ashy under 



surface ; under wing-coverts like the breast. — Oatesii. 



d. Above light brown, uniform ; throat white, contrasting with 



the fawn-buff breast ; under wing-coverts fawn-colour.— fiallidus, 



moaestus, etc., etc. 



The fawn-coloured under wing-coverts of B. pallidus, the ashy 

 brown throat and chest of B. chocolatifius, the reddish brown upper 

 surface, and entirely white under surface of B. Mariqteensis, success- 

 ively prevent B. Oatesii from being considered synonymous. A bird, 

 determined as B. mierimis (F. and H.), from the Congo (Sharpe and 

 Bouv., Bull. Soc. Zool. France, 1877, p. 478), would appear to be the 

 same as B. Oatesii, but is in worn plumage.
