the tibiae somewhat) rather bviffy yellow ; the sides of neck and body 

 olivaceous. Axillars and inner wing coverts sulphur yellow ; the 

 crissum similarly colored, but duller. Quills almost black, edged 

 internally with grayish-white, externally with olive ; tail feathei's 

 more olive-brown, edged internally with greenish-yellow, externally 

 with bright olive. A broad stripe of pale yellowish from bill over 

 and behind eye to nape, becoming paler when it reaches the eye, and 

 with a faint indication of a dvTsky border above it ; a dusky brown, 

 well-marked stripe from bill to eye, and a small spot of the same 

 behind it. The bill is almost black, except the basal half of lower 

 mandible, which appears to have been nearly white. The legs are 

 blackish -plumbeous. '' Iris brown " ( ItVood) ?

This interesting new species of Vireo is among tlie largest of 

 the genus, considerably exceeding in size V. olwacea, and fully 

 equal to Y. calidris of Jamaica. In general appearance it 

 closely resembles the latter, but there is even less of tlie grayish 

 cap, and the dusky mandibular stripe is wanting ; the under 

 parts are rather more olivaceous ; the bill is of about the same 

 size. The much rounded wings constitute an important char- 

 acter of the species. 



The much larger size, almost black bill and feet, absence of 

 ashy cap, more olivaceous under-parts, will readily distinguish 

 the species from Y. oUvacea. The wings, also, are much more 

 rounded ; the first quill about equal to the sixth, instead of 

 being but little shorter than the fourth. The wing formula is 

 much the same as that of Y. agilis, but the size and coloration 

 are very dift'erent. 



This species is one of several new species of birds in a col- 

 lection made at Belize, British Honduras, for Dr. Henry 

 Bryant, by Mr. Christopher Wood.
