We have again to offer to the Society descriptions of six appa- 

 rently new species of birds from collections made in Ecuador and 

 Peru, that have lately reached us.

Brunnescenti-oUvaceus pileo medio castaneo-rufo, utrinque lined

 lateraliter in cinereum trahens, crisso et campteriis alarum 

 fiavescentibus : rostro corneo, pedibus pallide corylinis : long,

Oba. Species pileo ad B. coronatum, ventre albo ad B, leucoble- 

 pharum et hujus affines magis appropinquans. 



This species must be placed in the section " B, b " of the genus 

 as divided by Sclater (P. Z. S. 1865, p. 283), near B. leucoblepharus 

 and B. stragulatus, although its head-colouring is that of B. coro- 

 natus (section B, a).
