Hab. Columbia river to Chili and Buenos Ayres. 



Th&ScolopaxguaraunaoilAwme.ns, viSiS founded upon the CrMaraMwa 

 of Margrave, a name given to a young bird said to have come from 

 Brazil. Although it is impossible to decide with certainty what this 

 bird really was, it is possible that it was the young of the present 

 species, as it is not known that any other species oi Falcinellus is found 

 in Brazil. It will be best, however, even if a second species of this 

 genus should be ascertained to inhabit Brazil, to retain the name of 

 guarauna for the present bird, as otherwise a new name • altogether 

 would probably have to be given to it, since the only one which has 

 certainly been applied to it, the chalcoptera of Temminck, had al- 

 ready been given previously by Vieillot to an African Ibis. The 

 species has a wide distribution, ranging, according to Ridgway, from 

 Chili and Buenos Ayres to the Columbia river. 



A white band, enclosing the eye, passes around the entire base of 

 bill. Head, neck, and underparts purplish chestnut. Back with 

 metallic purple and violet reflections. Wings and tail bright green, 

 varying with bronze and purple in certain lights. Shoulders reddish 

 chestnut. Under tail-coverts have also metallic green and violet 

 reflections. Bill apparently dark red.

Hab. Lake Titicaca. Peru. 



This form, thus far only known from Peru, is closely allied to the 

 previous one, F. guarauna, but seems not to have the white front 

 on the head. Several specimens are in Messrs. Salvin and Godman's 

 collection, sent by Mr. Whitely from Peru. It is probable that the 

 species has been confounded with the F. guarauna ; for it seems 

 hardly probable that it should be restricted to Peru, as all its relatives 

 wander over such vast extent of country. It is not unlikely that its 

 range will be found to be much greater than is at present supposed. 



Head and neck dark chestnut-red, or purplish chestnut. Back 

 dark green, with metallic purple reflexions. Wings metallic grass- 

 green, with bronze and bright purple reflexions. Primaries bright 

 grass-green. Entire underparts dark purple, the under tail-coverts
