 a median ridge ; the tongue 6 twelfths long, emarginate, and finely papil- 

 late at the base, flat above, slit at the point. The width of the mouth is 5 

 twelfths. The oesophagus is 1 inch 10 twelfths long, its greatest width 2^

WHITE-EYED VIREO. 



VlREO NOVEBORACENSIS, BoNAP. 

 PLATE LXIII. Vol. I. p. 328. 



I HAVE ascertained that this species is a constant resident in the 

 Floridas during winter, as well as in the lower parts of Alabama and 

 Georgia. A great number, however, pass beyond our limits, for at 

 Galveston Island I found them arriving from the south. It extends 

 its movements across the whole continent, Dr Townsend having met 

 with it on the Columbia River. Along our Atlantic districts it is 

 found sparingly in summer as far as Nova Scotia, and a few were seen 

 by me in Labrador. The eggs measure four-eighths and three-fourths 

 in length, and half an inch in breadth.
