 Vireosylvia cobanensis, Sclatee, P. Z. S. 1860, 463 (Coban).— Ib. Ann. 

 Mag. N. H. 1861, 328. 



Hab. Eastern North America to Hudson's Bay and Maine, sontli to Costa 

 Eioa and Guatemala. Not recorded from Mexico or West Indies. 



(No. 20,643, % .) Above dark olive green, tinged with plumbeous ash ex- 

 cept on the rump ; top of head and nape purer plumbeous ash, not edged with 

 dusky, the line of demarcation In- 

 distinct. Beneath light sulphur 

 yellow, paler and almost white on 

 chin and middle of abdomen ; sides 

 more olivaceous. A whitish stripe 

 from bill over eye, as also a patch 

 beneath it and the eyelids ; a dusky 

 loral and post-ocular spot. Quills 

 and rectrices brown, edged exter- 

 nally with olive, internally with

paler outer edges. Bill blackish, paler plumbeous below. Legs plumbeous. 

 Spurious outer or first quill (seen in gitva) wanting ; the outer about equal 

 to 5th ; 3d longest ; 2d and 4th not much shorter. 



(No. 20,643, % .) Total length, 4.80 ; wing, 2.65 ; tail, 2.25 ; difference be- 

 tween outer and longest primary, .28, of longest and innermost, .62; length 

 of bill from forehead, .54, from nostril, .30, along gape, .61 ; tarsus, .65 ; middle 

 toe and claw, .52 ; hind toe and claw, .44. 



Specimens vary somewhat in purity of tints, and especially in in- 

 tensity of yellow of under parts, which color is deeper in autumnal 

 skins. 



I regret that I led Mr. Sclater into an error by informing him that 

 the Vireo subsequently described by him as V. cobanensis was differ- 

 ent from V. philadelphica. The skin forwarded for examination by 

 him appeared to differ in some noticeable points, but those subse- 

 quently received from Mr. Salvin and other sources agree exactly 

 with specimens from Wisconsin and Hudson's Bay.
