338 TWO CENTENARIES AND A QUARTER 



Total length 9 inches ; bill, gape 1^; front -^jj-, wings 4 ; 

 tarsus, 1^; middle toe and claw Ifg, hind ditto U. This is 

 the only species I have yet seen, having the commissure regu- 

 larly curved, and the culmen consequently more bent doivii- 

 wards, than the gonys is upwards. In other respects there is 

 nothing remarkable in the structure or the plumage : the 

 colours above are black, striped with olive on the side of each 

 feather : the under tail covers are black, with a few interrupted 

 bands of whitish : flanks and thighs greyish olive, with white 

 transverse bands. Bill and legs greenish. 



170. Gallinula flavirostra. 



Entirely deep black : bill fine yellow : legs bright red. 



Inhabits West Africa. Mus. Nost. Rallus carinatus, 

 Classif. of Birds, Vol. I. p. 158. fig. 86. c, d. 



Total length 7 inches; bill, front, nearly 1; wings 4^^ ; 

 tarsus 1|; naked space above the knee ^; middle toe and 

 claw 2 ; hinder ditto ^. Confounded with one or two others, 

 under the name of R. niger. Carpus ending in a small acute 

 slender spur, ^ of an inch long, curved inwards, and nearly 

 hid in the feathers, but probably moveable in the live bird. 

 I have reason to think the elevation of the bill, in the specimen 

 figured as above quoted, is accidental, for another, since ex- 

 amined, had not this peculiarity. As the name of carinatus 

 would, therefore, lead to error, I now substitute that of ^am- 

 rostra. It seems to be one of the supposed varieties of G. 

 nigra. 



171. Gallinula alhifrons. 



Front of the chin, neck, breast, and body, white : 

 sides of the head, neck, and breast, rufous: flanks 

 banded with black and white : upper plumage olive 

 brown. 



Inhabits Brazil. Mus. Nost. 



Total length about 5\ inches ; bill, front, ig ; vvings 3 ; 

 tarsus 1 ; middle toe and claw \\ ; hinder ii; inner toe ^ shorter 

 than the outer. Bill greenish : legs pale : the rufous which 

 is on the side of the head, ears, and neck, ceases at the breast; 

 the body, belly, and thighs are cream coloured white, quite 

 pure, but the under tail covers are deep rufous. 



172. Alegthelia lineata. 

 Above, blackish, varied with numerous undulated 

 transverse lines of light fulvous brown ; beneath, whit-
