Norr.—Specimens received since the preceding account of the 
Sylvicolidz went to press furnish the occasion for the following 
observations and corrections :— 
Parula pitiayumi. Page 170. 
Among the collections made during the past winter, by Col. 
Grayson, in the Tres Marias, Mex., were several specimens of a 
Parula, which I cannot separate from the true South American 
P. pitiayumi; differing only in rather larger size and less amount 
of black in the loral region, which, in fact, is nearly as plumbeous 
as the forehead, the space immediately anterior to and beneath the 
eye being blackish. The upper parts appear rather paler than 
usual. They differ from the Guatemalan and Costa Rican ¢nornata 
in the larger size and possession of two white bands across the 
wings. The species has not been identified as occurring on the 
main land of Mexico.
