Habitat. The western side of Pichincha, in Ecuador, at an elevation of 6000 feet. 



Mr. Eraser, who procured this bird at Pallatanga, says, " Bill black ; feet dark flesh-colour ; gizzard contained 



insects ; found in the underwood." 



The members of the next genus, Atigastes, have perhaps no direct alliance with the preceding ; but as they 

 are characterized by masked faces, and have bufl^y marks on the sides of the chest, they are as well placed here as 

 elsewhere. 



Both the A. scutatus and A. Lumachellus are very beautiful species, and have had the trivial name of Vizor- 

 bearers applied to them, from the very peculiar manner in which their entire faces are covered with shining 

 metaUic feathers, giving the birds the appearance of being masked ; the under-surface of their tails is also luminous, 

 in which respect they present a similarity to the Metallura. 



Genus Augastes, Gould. 



(Kvyd^oy, iilucesco, de avyr]^ splendor.) 

 Generic characters. 



Male, — Bill straight, longer than the head, and inclining to a wedge-shape at the tip ; head round, the feathers 

 not advancing upon the bill ; wings rather long ; tail moderately long and square, the feathers broad ; tarsi clothed ; 

 feet small ; hind toe very diminutive ; face and tail luminous. 



Female. — Destitute of luminous colouring.

Habitat, Central and Northern Brazil. 



One of those genera which give but little trouble to the ornithologist is the 



Genus Petasophora, G, R, Gray, 



all the species having characters in common, while each has its own peculiar distinction either in colour or 

 markings. The sexes are alike in colour, but the females are always much smaller than the males. This is strictly 

 an Andean group, most of the species being found in those elevated regions from Mexico in the north to Bolivia in 

 the south ; one species, the P. serrirostris, inhabits Brazil.
