This species resembles the preceding in its general characters, 
and in the disposition of its colours. It differs much in size. 
But from its accordance in more material points we do not hesi- 
tate to refer it to the same group. 
The specimen in the collection was met with By Mr. Brown 
near Prospect Hill.

the types of the genus, are set apart from almost all the other 
species of the family by the formation of their wing, in which 
the first quill-feather is extremely short, in some instances, in-
