band across the £ore-neck deep black ; a grey mesial line along- 

 the top of the head to the nape, extending across to the sides of

 and extending along the sides of the crown to the nape ; throat, 

 middle of breast, middle of abdomen, and nnder tail-coverts 

 white; sides of breast and flanks ash-grey; axillaries and 

 marginal under wing-coverts yellow, remainder of the under 

 wing-coverts green ; under surface of flight-quills and lower 

 aspect of tail hair-brown.

The male described above was collected by Mr. McOonnell at 

 Mount Roraima during his expedition in October 1898. 



Adult female. Similar to the adult male on the upper surface 

 but differs on the under surface, in the absence of the black band 

 across the fore-neck, in being isabelline on the throat and breast, 

 and duskv on the sides of the breast and flanks. Wing 60 mm. 



Two young birds from Bartica are dark and almost invisible 

 green on the back and wings, the head dusky with scarcely any 

 ])attern apparent, and the under parts entirely dusky showing no 

 indication whatever of the adult jtlnmage. A third one, collected 

 on the Al)ary Tiiver in September 11)07. is more advanced on the 

 up|)er parts, where the characters of the adult plunuige are plainly 

 indicated, but on the under surface it is similar to ilie two nlnn- 

 tioned above.

 hopping about in the low bush of the dense woods in search of 

 insects. The " Arekunas ^''call it Kaxoaripoami.
