Muscicapa melodia, Wils. Am. Om. V, 1812, 85, pi. xlii, fig. 2. 



Hab. Eastern North America to Fort Simpson. Cordova and Oaxaca only 

 southern localities recorded. Not West Indian. 



(No. 1,017, 9.) Above olive green, strongly glossed with ashy; the head 

 and nape above more distinctly ashy, but without decided line of demarcation 



behind, and without dusky 

 edge; rump purer olive. Stripe 

 from nostrils over eye to nape, 

 eyelids, and space below eye 

 creamy white. A rather dusky 

 post-ocular and loral spot, the 

 latter not extending to the bill. 

 Under parts white, with tinge 

 of greenish-yellow (occasion- 

 ally of creamy fulvous or buflT ) , 

 especially on breast ; sides 

 more olivaceous. Crissum and axillars scarcely more yellowish. Quills and 

 rectrices wood brown, edged internally with whitish, externally with olivace- 

 ous, except perhaps on longer primaries. Edge of wing white. Larger wing 

 coverts grayish-brown, with paler edges, and no trace of olivaceous. Bill 

 horn color above, paler below. 



First quill very short or spurious ; 2d about equal to, generally rather longer 

 than 6th ; 3d longest ; 4th, then 5th a little shorter. 



(No. 1,017, 9.) Fresh specimen: Total length, 5.33; expanse of wings, 

 8.35; wing from carpal joint, 2.85. Prepared specimen : Total length, 4.80 ; 

 wing, 2.75 ; tail, 2.25 ; difference of 3d and 10th quills, .73 ; exposed portion 

 of 1st primary, .58, of 2d, 1.8S, of longest (measured from exposed base of 

 1st primary), 2.12; length of bill from forehead, .56, from nostril, .28, along 

 gape, .63 ; depth of bill, .15 ; tarsus, .65 ; middle toe and claw, .51, claw alone, 

 17 ; hind toe and claw, .41, claw alone, .19. 



The preceding description is from a female specimen which does 

 not differ appreciably from the male, but is a little smaller. Young 

 and autumnal specimens are perhaps a little more brightly colored. 



Vireosylvia gilva. (Pennsylvania.)
