The adult mules of the latter closely resemble S. v. ndpina, but, as a rule, 

 there is more or less of brownish admixture iu tlie fox-red of the najje, while the 

 females differ at a glace in having the nape and back olive-browu like the rump, 

 the ])ileum alone being rnfons. In adilition to the two t_v]>e-s])ecimi'ns from Forte 

 do Hio Branco (Natterer coll., Vienna Musenm) I have before mc sixteen skins from 

 the middle and uppsr Orinoco (Altagracia, Maipures, Caicara, CJiudad Bolivar; 

 Cherrie & Klages coll.), fonr from the Pnrus River,* and one from the Upper 

 Sarare (Geay coll., Paris Museum). In contradiction to a former statement of mine,t 

 I find that examples from North Peru (Nauta, Pebas) likewise belong to alopecias 

 and not to culpinu. S. vulpectda % is, therefore, most probably synonymons with 

 alopecias, yet a series from the Ucaj'ali should be examined.

This is the first record from the Rio Madeira. The bird agrees with Spix's 

 type in the Munich Museum, except iu being much brighter underneath because the 

 latter is extremely faded through exposure to light. The lower jiarts are clear 

 buify, the inner sides of the breast and the flanks slightly tinged with olive; the 

 feathers of the foreneck show obsolete edges of dark olive.
