M. de Lafresnaye has kindly identified for me as being of this 

 species. 



The apical portion of the outer primaries in this bird is black, 

 which colour gradually diminishes ia exteat m the succeeding feathers, 

 and is reduced to a minimum in the secondaries, where it only forms 

 a blotch at the ends. The first quill is nearly wholly black, and in 

 those next succeeding the šame colour advances far up the stems, being 

 broadly margined outwardly with chestnut, and inwardly with paler 

 cinnamomeous. 



6. Anabates erythropterus, sp. nov. ? 



A. supra pallide brunnescenti-cinereus ; alis extus et cauda totarufis, 

 remigum exteriorum parte apicali nigra : loris oculoruM ambitų 

 et gula cum tectricibus subalaribus cinnamomeis : corpore cetero 

 subtus pallide cinnamomescenti-albido, lateribus olivaceo tinctis : 

 rostro albido, culmine nigrescenti-plumbeo : pedibus pallidis. 

 Long. totą 6 •2, alse 3' 6, caudse 3'1. 



The only Anabates I know of likely to resemble the present species 

 is A. guianensis (PI. Enl. 686, fig. 2). I have never seen that bird, 

 but if it has been correctly deseribed, there is no doubt that this 

 species is distinct. 



7. Xenops rutilans, Temm. PI. Col. 72, fig. 2. 



A Bogota skin received from MM. Verreaux seems referable to 

 this bird, though there is rather more black in the tail than m my 

 Brazilian specimens. 



8. Margarornis brunnescens, sp. nov. (Plate CXVI.) 



M. umbrino-brunnea, capitis dorsigue siiperi pennis obsolete et an- 

 giistissime nigro marginulatis : infra pallide ochracescenti-albo 

 guttulata, his guttulis nigro cinctis et deinde umbrino-brunneo 

 terminatis : loris et gutture medio ochracescentibus, nigrescente 

 paululum variegatis : rostro superiore nigro, inferiore flavido, 

 pedibus clare brunneis. 

 Long. totą 5-5, alse 2-5, caudse 2*5. 



MM. Verreaux have transmitted me a single specimen of this bird, 

 which forms a second species of the genus Margarornis,^ instituted 

 by Reichenbach for the Anabates sąuamiger, Lafr. & d'Orb. M. 

 de Lafresnaye has also coined the name Anabasitta for the šame 

 form, but I believe the first-raentioned term has a sUght priority. 

 The type of the genus is very common in coUections from Bogota. 

 The present bird may be distinguished from it at once by the want 

 of the bright chestnut colouriug on the back and tail. In form, 

 however, there is not much difference. In M. brunnescens the beak 

 is rather longer, and the first two primaries proportiouately rather 

 shorter. The elongation of the naked stems of the rectrices is carried 

 to a greater extent in the present species than in the other. There 

 are tvvelve tail-feathers, and they all termmate in a similar hair-hke 

 pomt. The plumage of the two species below shows much similarity, 

 but in the "brunnescens" the tear-like spots are yellowish.
