feathers. But it is not the less certain, that all 

 these birds have the head and the neck bare when 

 they are full grown. 



The late M. Mace sent from Bengal to the 

 Museum several individuals of a species very 

 nearly allied to this, which has the beak a little 

 longer, and less arched, of which the first quill 

 only has a little black on the two edges of its 

 point, and of which the secondary quills are also 

 somewhat attenuated, and slightly tinged with 

 reddish. 



It appears, according to M. Savigny, p. 25, 

 that M. Levaillant observed another still, which 

 has the secondary quills similarly elongated, but 

 of which the neck always retains its feathers, and 

 whose face is of a red colour. 



The same M. Mace also sent us a tantalus, 

 very much resembling that which has been re- 

 garded by naturalists as the ibis, but of which 

 the small wing-coverts, and a broad band at the 

 lower part of the breast, are black, and speckled 

 with white. The last secondary quills are elon- 

 gated, and tinged with rose-colour. It is known 

 that, in the Tantalus ibis of naturalists, the small 

 wing-coverts are speckled with purplish red, and 

 that the whole under part of the body is white. 



We give here a table of the parts of some of 

 these birds, which could be accurately measured 

 in stuffed individuals. By comparing them with
