dibles of an equal height, neai-ly linear, and becotmng sharp near the point; 

 the upper one hardly arcuated. 



Africa, and the countiics bordering on the Indian Ocean, produce a genus 

 of birds neighbours of the Thrushes, which I call 



Philedon. 



Their beak is compressed, slightly arcuated throughout its length, and 

 emar^ate near the point; nostrils large, and covered by a cartilagmous scale; 

 their tongue terminated by a pencil of hairs. 



EULABES, CuV. 



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, Cuv. 

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

 countries bordei'ing on the Indian Ocean. Their beak is compressed, very 

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

 that of the Starling. They have the habits of Starlings, and like tlxem, pur- 

 sue insects in flocks. 



Pyrrhocorax, Cuv. 

 The compressed, arcuated, and sloped beak of the Thrushes; but their nos- 

 trils 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 



Oriolus, Lin. 

 Or the Orioles, whose beak, similar to that of the Tlunishes, is merely a little 

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



Gymnops, Cuv. 



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 

 pencUlated as in Philedon. 



MjENURa, Shaw. 

 These Birds evidently belong to the order of the Passerinse, and approach 

 the Thrushes in their beak, which is triangulai* at base, elongated, slightly 

 compressed, and emarginate near tlie point. They ai-c distinguished by tlie 

 great taU of tlie male, which is very remax'kable for the three sorts of feath-
