SYI.VICOLID.K — THE WAHUMiRS. 303 



Mr. John I5uiToii,y;li.s, of Wiishiiijrtiui, was so fortiinato as to olitaiii llio 

 nest and oui;s of tliis Warhlcr Udur lliu lii-ad-watcrs of tho Dclawavo IJivor, 

 in ]{oxl)iiry, Dolawari! ('(tiinty, N. V. "The nost," he \vnt(;.s luc, " was 

 in tiie (!(lHr(. of an old l)ai'k-i)eelinL(, in a hemlock wood, and was placed in 

 some ferns ahont om; foot from the jfround. The nest was iiuite massive, its 

 outer portions heing eomposed of small dry stalks and leaves. The cavity 

 was very deep, and was lined with tine black roots. I have freciuently 

 observed this Warbler in that .section. About the head of the Neversink 

 and Ksopus, in the northwest part of I'lster (,'ounty, New York, they are the 

 prevailing Warbler, and tlieir song may be heard all day long. Their song 

 suggests tiiat of the Kentucky (Jround Warbler, but is not so loud an»l fine." 

 iMr. lUirroughs states elsewhere that " tiie eggs, three in number, were of 

 light llesh-color, uniforndy sj)eckled with tine brown speck.s. The cavity of 

 the nest was so deep that the back of the sitting bird sank below the edge." 

 Their eggs are of an oblong-oval shape, ])ointed at one end. They measure 

 .75 l)y .5.') of an inch. Their ground-color is a pinkish-white, and they are 

 marked with dots and blotehes, of varying size, of dark i)urplish-browii.

The white eyelids of this species distinguish its males from those of (,'. 

 Ithiktdelphia, in which there is a black jugular i)atch not seen in the present 

 species. The females can only be known l)y the slenderer bill and more 

 rounded wing, the first quill being intermediate between the fifth and sixth, 

 instead of being considerably hniger than the fifth. 



The autinnnal adult male is as described al)ove, except that there is a faint 

 tinge of green on the crown, and the ashy borders to feathers of throat and
