The adult female from ( 'alama is typical of m'u/iiirostris, agreeing perfectly 

 with our large series from (Jayenne and Venezuela (Caura). The chest is ashy, 

 slightly tinged with pale fnlvescent, and the cross-bars of the lower brea'it and 

 belly are light rufescent brown. Tli(3 JFarmellos bird, on the oMier hand, is much 

 more rufous underneatli, the chest b?ing bright cinnamon and the cross-band.s of 

 the belly and tliighs being more deeply rufescent. It is practically identical with 

 an adult bird from EI Loreto, Rio Napo, Eastern Ecuador, in the Munich Museum, 

 while other specimens from the same district closely resemble typical m/tr/nirost/i.s. 

 Two adult males from the Rio Pnrns, and an adult female from the Upper Ucayali, 

 have similarly coloured nnder parts to those of the Marmellos e.vample. Without 

 additional material it is impossible to say whether these rufous specimens are 

 merely intergrades between tmgnirostri.s and iiatteri-ri (from the latter of which 

 they are not easily distinguisluible) or represent a constant, peculiar race.
