coverts. In M. xantJiopygus the latter parts are decidedly suf- 

 fused with ochraceous brown, while the throat, the belly, and the 

 rump show a pure and clear sulphur yellow. The olive-green 

 of the head above and of the upper back presents more a brownish 

 or ochraceous shade in M. ridgwayi., while these parts are of a 

 purer green in M. xanthopygus. The tail-feathers in the former 

 are of a much deeper black, while they appear brownish black 

 with greenish margins in the Bahia skins. The bill is not so 

 broad in the new species, and the under mandible is darker, 

 being nearly white with a blackish tip in the other bird. The 

 wings in my Rio bird are a little shorter, the tail much longer, 

 than in the Bahia skins. Some time since when Mr. Sclater 

 wrote his 'Catalogue of the Tyrannld£e of the British Museum,' I 

 communicated my Rio specimen to him, pointing out in what 

 way it differed from M. xanthopygus (Spix), but my English 

 friend could not satisfy himself of its distinctness. He even does 

 not admit M. xanthopygus as a species, which is different from 

 M. barbatus by its brownish jugulum, sides of body, and under 

 tail-coverts, etc. Nevertheless, I am fully satisfied with the valid- 

 ity of all these species, and I trust Prof. Ridgway supports 

 this oi^inion.

DiAGN. — S. corpore supra saturate brunneo, pileo obscuriore vel minus 

 rufescente. Stria siiperciliari &\i-pra oculos incipiente lata ad nucham ducta 

 cum capitis et colli lateribus (his sordidius) rufo-badiis. Corpore subtus 

 sordide brunneo-griseo, gula abdomineqae pallidioribus fere albo-griseis. 

 Mento rufo tincto. Remigibus earumque tectricibus superioribus rufo- 

 brunneo marginatis. Rectricibus externis — nisi pogonis interne parte 

 basali fusco marginato — fere omnino rufo-brunneis, mediis pogonio in- 

 erno fusco, externo rufo-brunneo. Tectricibus alarum inferioribus et 

 remigum margine basali intus rufis. Rostro — nisi mandibulae dimidio 

 basali flavo — et pedibus cornels. 



Rectricibus omnibus in parte apicali angustatis barbis decompositis 

 fere ut in S. fuligitiosa, cui affinis videtur haec nova species.
