and the cheeks, ear-coverts and sides of neck dingy olive-grey (instead of deep 

 buff). Furthermore, the interscapular region is darker, dull rufescent brown, with 

 a greyish tinge (instead of bright tawny brown). 



I am unable to discover any other constant differences. Though the type 

 has rather light ochreous under parts, passing into buffy whitish (not " greyish 

 white," as said in the original description) on the throat, the Cayenne bird does 

 not differ in this respect from Upper Amazonian examples. 



The two races are, however, closely allied, and represent each other geo- 

 graphically, so that their natural relationship seems more correctly expressed by 

 trinomials. I herewith give the synonymy, together with a short re'sumS of their 

 range and characters.

Hab. Upper Amazonia, ranging from the head-waters of the Rio Napo 

 (Sarayacu), in Ecuador, south through Eastern Peru (Xeberos, Chamicuros) to the 

 Oarabaya district (Yahuarmayo) in South-eastern Pern, and east to the left bank of 

 the Rio Madeira (Humaytha), Western Brazil. 



Characters. Upper back (interscapulium) bright tawny brown, without 

 greyish admixture ; lores buff; cheeks, malar region and auriculars somewhat 

 deeper buff, along the upper edge of the ear-coverts an extremely narrow streak 

 of olive ; sides of the neck olivaceous. 



Examined. Three adults (including the type of N. rubicunda) from Chami- 

 curos, one from Sarayac.u, East Ecuador, in the British Museum ; one cT ad. 

 Humaytha, Rio Madeira, in the Tring Museum ; and one <? ad. from Yahuarmayo, 

 Carabaya, S.E. Peru, H. & C. Watkins' coll., in the Munich Museum. 



Obs. The bird from Hnmaytha agrees in coloration with that from Yahuar- 

 mayo, but is decidedly smaller and has a slightly shorter bill.
