 Olivaceus, alis caudaque brunnescentibus ; pileo castaneo, 

 striga utrinque cinnamomea ; fronte et capitis lateribus 

 nigris, ilia albo trimaculata ; subtus albus, lateribus et 

 ventre imo cum subalaribus cinereis olivaceo indutis, 

 campterio flavo ; rostro nigro ; pedibus carneis : long, 

 tota 7'5, alae 3'2, cauda 3'0. 



Hab. in rep. ^Equatoriana : Pallatanga (Fraser) ; Jima 

 (Buckley). 



Mus. P. L. S. et S.-G. 



Obs. Similis B. brunneinucho, sed torque collari nullo. 

 Two examples of this species, collected by Fraser at Pal- 

 latanga, were considered by Sclater to be the young of B. brun- 

 neinuchus. The receipt of further specimens, in exactly the 

 same plumage, renders it necessary to separate the species. 



We have not had an opportunity of examining Peruvian 

 specimens which have been called Arremon frontalis by 

 Tschudi (Faun. Per. Aves, p. 213) and B. brunneinuchus by 

 Taczanowski (P. Z. S. 1874, p. 515).
