8 TROCHILIM;. 



Hab. S.E. Brazil, Paraguay, and N. Argentina. 



Dr. Burmeister states that this species is found near Tucuman in 

 company with Calliperidia furcifera and Petasophora serrirostris ; but 

 we have no other authority for its occurrence within the limits of the 

 Argentine Republic.

 hue, inclining to brown on the head ; wings purplish brown ; tail of a very rich 

 golden lustre both above and beneath ; chin buff; under surface grey, washed 

 with a golden hue, which is richest on the flanks ; vent and thighs white ; 

 under tail-coverts grey, with a slight golden lustre ; bill fleshy, red at the base

Hab. S. Brazil, Paraguay, and N. Argentina. 



Hans v. Berlepsch has lately shown that Azara described this species 

 under the designation " Picaflor cola de topacio" and that it must 

 consequently bear the name ruficollis of Vieillot, instead of chrysura 

 of Lesson, by which it is more commonly known. It visits the more 

 northern portion of the Argentine Republic, and was obtained in the 

 vicinity of Buenos Ayres by Hudson at Conchitas, and by Durnford at 

 Punta Lara. The British Museum contains specimens from both these 

 localities.
