 This most elegant species of square-tail Manakin resembles the 

 P. cyanocephala, Vieill., but is at once distinguished by the general 

 blackness of its plumage, and especially by its having a black throat. 

 It might be taken for an undescribed state of that most variable 

 species, the P. serena, L., which however has always been found 

 with a white forehead, a blue rump, the blue colour of the head 

 much more circumscribed. The rufous belly will at once distinguish 

 it from the P. cyaneocapilla of Wagler, Isis, 1830. p.'934., figured by 

 Spix under the name of P. coronata, II. 67. f. 1. As to the Pi2)ra 

 Musica (Euphonia cceruleocephala, Sw.), it diiFers by its black frontlet 

 and orange rump.

Two sjiecies have been confounded by authors and by Wagler 

 himself under the name of Pipra caudata, which are however well 

 distinguished by the shape of the elongated tail feathers. The name 

 of P. caudata must be retained, for the species figured by Shaw, t. 

 153. Nat. Misc. V. whilst the longicauda of Vieill., of which D'Azara 

 speaks under the characteristic name of Queue en pelle is at once 

 distinguished by the dilatation in the apex of its elongated tail- 

 feathers. We subjoin the characters of both.
