208 VIEEONID^. 



pallide bninnea ; subtus flavicans, gutture grisescenti-albo, pectore et lateribus ochracescenti-fuscis ; rostro 

 corneo, pedibus corylinis. Long, tota 4-3, alae 2-2, caudse 1-75, rostri a rictu 0-65, tarsi 0*65. (Descr. 

 maris ex Choctum, Guatemala. Mus. nostr.) 



Hab. Mexico, Playa Vicente (Boucard'^), Oaxacal^; Guatemala^ Choctum^, Chisec 

 (0. S. & F. D. G.) ; Costa Kica, Angostura (Carmiol^^) ; Panama, Bugaba (ArcS^). 



H. ochraceiceps has a very similar range to that of H. decurtatus ; but, though probably 

 more common in the eastern parts of Southern Mexico, it has not yet been detected on 

 the isthmus of Tehuantepec, nor, indeed, on the shores of the Pacific anywhere in its 

 range until we reach its extreme limit on the slopes of the Volcan de Chiriqui. It was 

 first discovered by M. Boucard at Playa Vicente in 1859 i, and in the following year we 

 obtained several examples from the forests of Northern Vera Paz, and in 1862 observed 

 it ourselves in this district, the only one in Guatemala in which we know it to occur. 

 Here it frequents the same woods as H. decurtatus, the habits of the two birds being 

 quite similar. The sexes are alike in plumage.

Supra saturate olivaceus, dorso medio dUutiore ; alis nigrioantibus, extus dorse concoloribus ; cauda fusceseenti-

Mob. Panama, Bugaba ^, Santa Fe ^ (Arce), line of railway (M'Leannan ^ ^, Hicks ^). 



This bird is very closely allied to a Colombian species, H.Jlavipes, Lafr., — so much so 

 that their distinctness is open to doubt. Mr. Sclater in his recent monograph^ 

 reluctantly kept them apart, stating at the same time that the only difierence he could 

 detect consisted in the paler, more faded hue of the yellow belly of the Colombian 

 bird, a Venezuelan example of H. flavipes being still more difficult to distinguish. 

 With no additional materials to throw further light on the question, we follow 

 Mr. Sclater's lead. 



H. viridiflavus is easily recognized from the other Central-American species by its 

 yellow legs, which it has in common with H. flavipes. The back is wholly olivaceous, 

 also a distinguishing character so far as Central America is concerned. 



This Hylophilus was discovered in 1861, by M'Leannan and Galbraith, on the line of 

 the Panama railway, the latter remarking that it was rare, only one having been 

 obtained in the jungle ^. Since then Mr. Hicks also observed it ^, and a few specimens 

 have reached us from our collector Arce from more western parts of the State of 

 Panama ^ ^.
