the back, some of the greater ones slightly inclining to brownish, 

 with a narrow white margin ; a conspicuous patch of white feathers 

 along the edge of the wing ; quills brownish, washed externally with 

 grey, the secondaries much darker on the inner web, where they are 

 slightly glossed with greenish and narrowly margined with white ; 

 the inner webs of all the feathers white at the base, this colour 

 extending uninterruptedly for nearly half the feather, and broken 

 towards its apical extent by a few more or less interrupted bars of 

 greyish brown ; tail greyish brown, with a decided wash of clearer 

 grey on the outer web, all the feathers tipped with white, the outer 

 ones very broadly, with a distinct blackish bar crossing the tail just 

 before the white tip, the centre feathers longitudinally spotted with 

 white along the shaft, these spots increasing in size towards the 

 outer feathers, which are also notched with white on the inner web, 

 till on the outermost they form very distinct white bars across the 

 feathers ; sides of the face of the same colour as the head ; lores, 

 feathers in front of the eye, fore part of cheeks, and entire throat 

 pale bluish grey ; lower part of throat and fore neck bright 

 chestnut ; rest of under surface buff, strongly shaded with chestnut 

 and crossed with very narrow blackish lines ; under tail-coverts 

 uniform rich buff ; under wing-coverts buff, with very narrow 

 blackish vermiculations ; bill rich orange, blackish along the culmen 

 and towards the tip of both mandibles ; feet deep yellow. Total 

 length 13"4 inches, culmen 105, wing 87, tail 7'0, tarsus - 95.

To the same extent that Cuculus gularis differs from C. canorus 

 does this new bird differ from C. gularis. It might be supposed 

 that a new Cuckoo of this group, coming as it does from Sene- 

 gambia, must be the true G. lineatus of Swainson ; but neither his 

 description nor figure agrees at all ; and there can be no doubt that, 

 as in the case of Oriolus capensis and other birds, he has figured a 

 South-African specimen, and that the species has no business in the 

 list of West-African birds. Like G. gularis, the Gambian Cuckoo 

 has the nostrils situated in, and of the same colour as, the yellow 

 portion of the beak ; but this is much more brilliantly coloured ; 

 hence the name suggested. The chestnut shade on the under parts 

 is another character ; while the cross bars on the under surface are 

 very much narrower than in true G. gularis. 



It is just possible that C. aurantiirostris may turn out to be the 

 C. ruficollis of Heuglin, or C. leptodetus of Cabanis and Heine, from 

 North-eastern Africa ; and a comparison of types is desirable. The 

 two latter are united without a query to G. gularis by von Heuglin. 

 On the other hand, the bird noticed by Hartlaub from Casamanze is 

 clearly C. aurantiirostris, so that it is by no means improbable that 

 Senegambia has its peculiar species of Cuckoo.
