THIS bird, Lesson observes, may prove to be the 

 young of the last. But although the form is very 

 similar, the colour seems so distinct, that it is unlike 

 what is seen in the others which vary from the young 

 to the adult plumage. In length it is little above 

 three inches. The head, back of the neck, and en-

 though dull, shews changes of tint with the position. 

 On the under side the colour is quite uniform, and 

 without any black patch. The lower part of the 

 back, rump, and the wing- coverts, are of a rich crim- 

 son, with golden reflections. The tail is deeply fork- 

 ed, and is of an indigo-blue colour on both surfaces. 

 It is a native of Brazil.
