EMPIDONAX. 71 
Ruatan I. (Gaumer) ; Costa Rica (Endres) ; Panama (M‘Leannan 1 11),—Ecuapor ; 
CUBA. 
A species of the Eastern States of North America, whose southern migration in 
winter extends to Ecuador, and it is also found sparingly in the southern portion of 
‘Central America; it has been recorded from Yucatan, and we have received several 
specimens from the island of Ruatan, but its southern range does not appear to spread 
westwards into Mexico or Guatemala. 
Its breeding-ground is certainly in the middle districts of the United States, but 
Mr. Dresser states that it is not uncommon in Texas in summer”. Its nest is described 
as made of strips of bark or stalks of weeds woven loosely together so as to make a very 
slight structure, so thin that the eggs may be seen from below. It is placed in the 
fork of a small branch from six to ten feet from the ground. The eggs are rich cream- 
‘colour with a reddish-brown shade, and marked irregularly at the larger end with vivid 
blotches of red and reddish brown.

We agree with Dr. Coues in considering Swainson’s name Tyrannula pusilla of diffi- 
cult, if not of impossible, application, and as the type is no longer extant, we see no 
hope of its being identified with certainty. It has usually been considered to refer 
to the species described and figured in the ‘Fauna Boreali-Americana’ under this 
name; but the original description was based upon a specimen from the “ maritime 
parts of Mexico,” and it is thus possible that the bird with its “even tail” we now 
know as E. flaviventris was that originally described by Swainson as 7’. pusilla, whereas
