tectricibiis superioribus extus olivaceo-griseo inconspicue 

 margiuatis ; rostro cyanescenti-plumbeo^ apice nigro, 

 tomiis pallidioribus, pedibus nigris. Long. tot. 162, 

 al. 78j caud. 73, culm. 15|, tai^s. 20 millim. 

 Hab. Angostura. One specimen. 



Obs. C. nnicolori (Kaup),*ex Amazonia, ut videtur, remigi- 

 bus concoloribus nee angustatis raaxime affinis, sed multo 

 major et corpore olivaceo-ardesiaco (nee nigro) di versus. 



I have not yet had an opportunity of comparing my specimen 

 with C. imicolor from Amazonia, but Mr. Sclater, after ex- 

 amination of the Angostura bird, assures me that it is quite 

 distinct and belongs to an undescribed species. No species 

 of Cnipolegus is yet known to extend its range so far north as 

 C. orenocensis. 



8. Myiozetetes texensis columbianus (Cab. & Heine). 

 Angostura. One specimen in faded plumage (long. al. 84^, 



caud. 68^, culm. 14, tars. 17^ millim.), agreeing with a bird 

 in my collection from Western Venezuela (coll. Goering), 

 the latter being in fresh plumage. 



Birds from Venezuela (named " texensis '' by Mr. Sclater 

 and others) differ constantly in many particulars as compared 

 with specimens from Central America. The diagnosis of 

 Messrs. Cabanis and Heine (Mus. Hein. ii. p. 62, descr. de 

 Puerto Cabello and Cartagena) does not fit it very well. I 

 therefore propose to distinguish the Venezuelan bird as 

 follows : — '^ M. t. columbianus ex Venezuela a M. texensi ex 

 Am. centr. alis caudaque brevioribus, fronte brunnescenti- 

 cinereo (nee albescente), pilei lateribvis obscurioribus, dorso 

 obscurius olivaceo, et gula magis flavo tincta distiuguendus.'^ 



9. PiTANGUS DERBYANUS RUFIPENNIS, Lafr. 



Angostura. One specimen. 



Long. al. Ill, caud. 86^, culm. 29|, tars. 24 millim,; 

 agreeing with a specimen from Puerto Cabello in Mus. H. v. B. 



In this race of P. derby aims the rufous on the tail- and wing- 

 feathers is of still greater extent than in typical birds from 

 Mexico, the outer tail-feathers being nearly wholly rufous. 

 In addition to this character the front is darker, more mixed
