sulpliureo-albis. Maxilla cornea, mandibula alba in apice 

 brmiiiescente. Pedibus corneis. 



Al. 52|, caud. 43£, culm. 9\, tars, loi mm. 



Habitat: Pto. Gabello (Venezuela). 



Typus: in Mus. H. v. B. : Pto. Gabello (Starke leg.) ex 

 Moeschier. 



Observât io : P. a P. eximio (Temm.) pileo grisescente, tectri- 

 cibus alarum bifasciatis, etc., a P. ophthalmico (Tacz.) gula 

 flava, pileo viridescenti-griseo nec ardesiaco, etc. dis- 

 ting'uendus. 



Tins new species seems to have its nearest ally in P. 

 ophthalmicus Tacz. of Peru, Ecuador and Colombia, but is 

 much smaller in all its dimensions, and has the pileum of a 

 much lighter greyish colour, suffused with olivaceous (not 

 blackish-cinereous as in that species) . The back is of a much 

 greyer olive-green, the white of the lores and the eye region 

 is replaced by yellowish-white, the throat is yellow (not 

 white), the yellow of the under parts is paler and not suffused 

 with olive-green on the breast. The yellow spots on the 

 tips of the upper wing-coverts are larger and clearer and 

 better defined. The bill is still a little longer than in 

 P. ophtlialmicus, but generally of the same shape, only a 

 little broader before the tip. The bristles are not quite as long 

 as in P. ophthalmicus. 



In general style of plumage this species shows some 

 resemblance to the species of Tyrannise its, and T. einer eiceps 

 Sci. agrees with it in the black lunar mark on the ear-coverts, 

 but it has the long slender bill and the long bristles of the 

 genus Pogonotriccus. 



A careful study shows that the bird placed by Mr. Sclater 

 (Cat. Birds XIV., p. 118) as specimen (a) under the head of 

 Leptopogon tristis belongs to the species just described, and 

 that L. tristis Sci. & Salv. from Bolivia, is quite distinct, 

 being only a large form of Phylloscartes ventrali* (Temm.).
