longest The bill is decidedly longer and stouter than that of V. oUvaceus, measuring above 

 about .Gl of an inch instead of .54. It is also narrow towards the end. The size, however, is 

 considerably less, the wings being a quarter of an inch shorter. The ash of the crown is not 

 80 well defined. 



The Phijllomanes barhatulus of Cabanis, from Cuba, (Journal fur Ornithologie, 1855, 467,) is 

 very closely allied to the present bird. 



VIREO PlIILADELPHICUS, Cassin. 



UieosyUia philaJelphiea, Cassin, Pr. A. N. Sc. Pliila. V, Feb. 1851, 153.— lu. VI ; pi. i, f. 1, Pliilailtlpliia. 



Sp. Cii. — Without any spurious primary. Second and third quills longest; fourth a little shorter; first about .20 of an 

 inch shorter than second, and about equal to the fifth. Above dark olivo green, slightly inclining to ashy on the crown ; 

 beneath pale sulphur yellow, briglilcit on the throat and breasl. A white line from the bill over the eye, and an obscure white 

 spot below it. A dusky line from the commissure through and behind the eye. Length about 5 inches; wing, 3.75; tail, 

 2.10 ; tarsus, .65 . 



Hob. — Pennsylvania to Wisconsin. 



This rare species resembles very closely in size and general appearance the V. gilvus, 

 especially those with a decidedly yellow tinge beneath. It will be, however, at once distin- 

 guished by the absence of the spurious primary. The under parts are very strongly sulphur 

 yellow instead of almost white ; the upper are darker and purer green ; the markings about 

 the head are better defined. The bill is smaller.
