cured at Minas Geraes, and gave a very poor figure of it. 

 We can find no differences in examples from various parts of 

 Brazil, and also from Cayenne. We have compared also spe- 

 cimens from Bahia, called P. eremita by Gould, with those from 

 Rio Janeiro and other parts of Brazil, and find them identical. 



Our specimens are as follows : — 



One, Brazil (Gould), one, ditto (Cook), one, Bahia (Dey- 

 rolle), Mus. D. G. E. ; one, Rio (Youds), two, Brazil, Mus. 

 S.-G. ; one, Brazil (Leadbeater) , Mus. P. L. S. 



Pygmornis nigricinctus.

Pygmornis nigricinctus, Gould, Intr. Troch. p. 48. 



Hab. Upper Amazons, Pebas (Hauxwell) ; Eng. do Gama, 

 Brazil (Natterer). 



This species, although resembling closely the P. pygmaus 

 and P. episcopus, presents one constant difference — that is, in 

 the extent of black on the mandible. In the allied species 

 mentioned above, the black extends halfway from the tip ; 

 in P. nigricinctus it is only the tip that is black ; and this cha- 

 racter seems always to distinguish it from its relatives. In 

 all other respects we find it resembles the two species with 

 which we have compared it. 



Specimens examined : — 



Two, Pebas, Peru (Hauxwell) , Mus. D. G. E. ; three, Pebas 

 (Hauxwell), one, Brazil (Natterer), Mus. S. & G.

Hab. Guiana. 



This species, although very closely allied to P. pygmaus, is 

 apparently distinct from that species, the principal point of 

 difference being in the tail, the feathers of which are much 

 broader and blacker. This character is not exhibited in Mr. 

 Gould's plate of the species, his differences being the bronzy 

 hue of the upper surface and tail, broad pectoral band, and
