another resident form of this group of Vireos, and therefore give it a distinct name. 

 At the same time it is highly desirable that more specimens should be sought for and 

 examined to place the bird on a settled footing,

Fraser is the recognized discoverer of this species, as his specimens, obtained near 

 Pallatanga, in Ecuador, vt'ere the types of Mr. Sclater's description ^ ; but an example 

 from Bogota has been lying in the Strickland collection since the year 1844^. We 

 also possess specimens from Jima, in Ecuador, and from the vicinity of Paste, further 

 north. Skins of it may also be found in trade collections from Bogota ; and it has been 

 traced still further north in Colombia by Salmon, who sent specimens from the neigh- 

 bourhood of Medellin, in the Cauca valley. In Central America we. only know it from 

 Costa Pica and the adjoining parts of the State of Panama; and from this we infer that 

 the bird affects mountainous districts of moderate elevation, where it is most probably 

 resident, and that it does not frequent low-lying lands near the sea-level. 



As already stated, in tracing the alliances of this species, Mr. Ridgway, in the ' History 

 of North -American Birds,' ^ refers to a specimen in the National Collection at Wash- 

 ington, sent from Orizaba by Prof. Sumichrast, which is quite intermediate between 

 V. gilviis and the present bird. He therefore places V.josej^hce as a "variety" of 

 V. gilvus. The two birds in their normal dress are so different that we hesitate to 

 follow this course. The ranges of the two birds are separated, so far as our present 

 knowledge goes, by a very wide interval ; and it seems to us unlikely that a complete 

 intergradation takes place between the two in any locality hitherto ornithologically 

 unexplored.
