with the head lead-coloured or blueish grey, the 

 body white beneath. 



Of the exotic Thrushes none are more remarkr 

 able than the celebrated bird called the Mocking- 

 Thrush, or mocking-bird of America, the T. Or- 

 pheus and Polyglottus of Linnaeus. Of this bird 

 an animated description may be found in Mr. 

 Pennant's Arctic Zoology. 



The genus Ampelis or Chatterer, which is very 

 nearly allied to that of Thrush, differs in having 

 the nostrils concealed by smajl bristles growing 

 over thenj. 



It is not a numerous genus, but is remarkable 

 for the extrenae splendor of its colour. The Am- 

 pelis Cotinga for instance, or Ultramarine Ampelis, 

 is of so intense and brilliant a blue as scarcely to 

 be surpassed by any other natural object, not 

 even by the blue exhibited on the wings of some 

 of the larger exotic Butterflies, The Pompadour 

 Ampelis is remarkable for its fine purple colour : 

 both these species are natives of South America*. 



* In the large picture at present before us, may be seen both 

 these beautiful species by the ingenious pencil of the Chevalier 

 de Bardej they are taken from select specimens in the Leveriai^ 

 Museum.
