pale chestnut, the innermost feathers ahiiost entire!}- of this color; 

 wing-coverts chestnut, deeper on the bend of the wino-, and niottled 

 with l)hickish; middle and g-reater coverts broadl}- tipped with huffy 

 white, most of the feathers with subterminal blackish bars; primarv- 

 coverts blackish, with broad hazel ])ars, the feathers mainly blackish 

 at tips; under wing-covints, bend of wing, and axillaries buff', with 

 blackish and rufous bars on outer border of the under wing-coverts; 

 tirst three primaries without hazel edging on inner webs, the remain- 

 der of the series conspicuously edged with this color: tail light hazel, 

 much paler on the tw o middle feathers, which are tinely, irregular!}^, 

 and indistinctly freckled with dusky, the outer feathers more heavily 

 marked and barred with blackish, the two outermost rectrices with a 

 white tip that, on the inner web of the last feather, is 13.8 mm. long; 

 lores, sides of head including ear-coverts, sides of neck and l)reast 

 chestnut, some of the feathers on sides of neck tipped with buff'y like 

 nape, those of the middle of breast terminated with buffy white, most 

 of them having also narrow, black shaft marks; chin and upper throat 

 cinnamon rufous; lower throat with two white spots, separated by a 

 narrow line of black-tipped rufous feathers, the lower border of these 

 white spots also with black-tipped feathers; cheeks mixed cinnamon 

 rufous and buffy white; abdomen and under tail-coverts buff', the for- 

 mer more or less obsoletely barred with brownish and rufous; feet 

 and tarsi light brown in the dried skin. Length of wing, 130; tail, 

 92; tarsus, 19; culmen, 10.5 mm. 



In the above description no mention is made of certain feathers of 

 the plumage that are apparently thos(^, of the immature stage, from 

 which the bird has recently emerged. These consist of a number of 

 butty gray feathers with fine darker vermiculations, that are scattered 

 over the forehead and sides of the crown; and several similar feathers 

 with blackish shaft lines, changing terminally to chestnut, that are to 

 be found among the inner scapulars. The butty under tail-coverts are 

 probably also of the inunature dress, as the feathers are of the char- 

 acteristic, flutt'y kind common to young birds. 



In order that there should l)e as little chance as possible for an error 

 in identification, Doctor Richmond compared the Abbott specimen 

 with that collected by Mr. D. G. Ellliot at The Haud in Somali Land, 

 and has furnished the following result: 



Our bird is so very similar that there can he no possible doubt regarding its identity. 

 The Somali Land specimen has more vermiculated gray feathers on the liead, back, 

 and wings, while the rump and middle tail-feathers are largely of this color, and the 

 other rectrices have more black; the white spot in the wing occupies the first four 

 primaries instead of three as in our I)ird; also the white tip of the tail is more exten- 

 sive than in ours. 



In measurements the wings are almost exactly alike; the tail in our bird is 92 mm., 

 in the other 97 mm.; the tarsus in both is the same, but the middle toe is nearl3'2.5 

 mm. longer in our bird.
