This is a rare bird in this State ; the specimen in the Cabinet of the Lyceum being the 

 only one I am acquainted with, within our territorial limits. It is very common in the Mis- 

 sissippi valley, but does not seem to be often found north of Carolina, except in Maryland, 

 where it is rather common. Its present ascertained geographical range is between Mexico 

 and New- York. It has a certain resemblance to Wilsonia pusilla, but is larger. Feeds on 

 spiders, insects and their larvae. The eggs are described as white, finely sprinkled with bright 

 red dots. Mr. Giraud states that a few have been obtained from the south side of Long 

 island ; and it has also been observed at Hoboken, and in Rockland county in this State.
