This is apparently a very distinct species of Elainea, be- 

 longing to the group with the wliite concealed vertical patch. 

 In size it is about the same as E. albiceps, but is of a much 

 brighter olive-yellow beneath. 



Mr. Whitely found this species on the slopes of Roraima, 

 at elevations between 3500 and 6000 feet. 



Chloropipo uniformis. 

 Saturate olivaceuSj subtus paulo sordidior^ gula cinereo vix 

 induta^ abdomine medio pallidiore ; rostro et pedibus 

 plumbeo-nigris : long, tota 5*4^ alte o'l, caudae 2-4, rostri 

 a rictu O'Q, tarsi 0"6. 

 $ mari omnino similis.

This rather singular bird seems best placed in the genus 

 Chloropipo, from the type of which, C flavicapilla, it differs 

 in having a rather longer tail and in the base of the culmen 

 of the bill being rather more flattened. In its general colo- 

 ration C uniformis might easily be mistaken for the female of 

 Xenopipo atronitens ; but the absence of the slightly metallic 

 gloss on the upper plumage of that bird, and the maxilla 

 being dark to the base, are characters which at once distin- 

 guish it on closer inspection. 



Mr. Whitely obtained a good many specimens of both 

 sexes at elevations varying from 3500 to 6500 feet, and 

 dissected examples show that there is no material ditfcreucc 

 in the plumage of the males and females. 



PiPRA IRACUNDA.

 capitis postici valde elongatis, fere ut in P. cornuta : 

 long, tota 4*4, alee 2*6, caudse 1'5, rostri a rictu 0*6, 

 tarsi 0"7.
