This species forms a connecting link between Sylvicola and Trichas, 
having the long pointed wings of the former, and the general appear- 
ance of the latter, which it resembles, especially in its tail, which is

Trichas. Some of the Sylvicolse are, in like manner, assimilated to 
Myiodoctes, and others to Vermivora. Of the former may be men-

burnice.

the head being ovate and of moderate size, the neck short, 
the body rather slender ; the feet of moderate length, slen-
