126 AVES. 



EULABES, Cuvier. 



The birds of this genus are closely allied to those of the preceding one. 

 Their beak is nearly that of a thrush ; their nostrils are round and smooth. 

 Their distinguishing mark consists in broad strips of naked skin on each side 

 of the occiput, and a bald spot on the cheek. 



GRACULA, Cuvier, 



Is another genus allied to the thrushes. The species inhabit Africa and the 

 countries bordering on the Indian Ocean. Their beak is compressed, very 

 little arcuated, and slightly emarginate ; its commissure forms an angle like 

 that of the starling. They have the habits of starlings, and like them, pursue 

 insects in flocks. 



PYRRHOCORAX, Cuvier. 



Have the compressed, arcuated, and sloped beak of the thrushes ; but their 

 nostrils are covered with feathers, as in the crows, to which they were for a 

 long time united. There is one in Europe. 



I can find no character sufficient to warrant removing from the thrushes 



OHIOLUS, Linnaeus, 



Or the orioles, whose beak, similar to that of the thrushes, is merely a little 

 stronger; the feet a little shorter, and the wings a little longer in proportion. 



GYMNOPS, Cuvier. 



The same strong beak as the orioles ; the nostrils round, without scales or 

 surrounding membrane ; a great part of the head naked. 



Some of them have prominences on the beak. In these the tongue is 

 pcncillated as in Philedon. 



M^ENURA, Skatv. 



These birds evidently belong to the order of the Passerine, and approach 

 the thrushes in their beak, which is triangular at base, elongated, slightly 

 compressed, and emarginate near the point. They are distinguished by the 

 great tail of the male, which is very remarkable for the three sorts of feathers 

 which compose it, viz. the twelve common ones with very fine and widely 

 separated barbs ; two more in the middle only one side of which is furnished 

 with thickly set barbs, and two external ones curved into the figure of an S, 

 or like the arms of a lyre, whose internal barbs, large and thickly set, form a 

 kind of broad riband, while those that are external are very short, becoming 

 longer only near the tip. The female has only twelve ordinary quills. 



The singular species, M<envra tyra, inhabits the rocky districts of New 

 Holland ; its size is somewhat less than that of the pheasant
