mistaken for one of the Formicariide. One specimen he killed was in the midst of an 
innumerable column of Tepegua ants (Eciton mexicanum), upon which he says it was 
doubtless feeding. | 
In Guatemala its range is very.restricted; and we are not aware that it occurs 
anywhere except in the forests which lie at an elevation of from 3000 to 4500 feet, 
between the Volcanos of Agua and Fuego. In September 1859 a pair were watched 
for some time, and afterwards secured, below the village of Alotenango in this district 4, 
Their restless motions recalled those of Setophaga; and they had the curious habit of 
expanding their tails and swaying them to and fro. Subsequently our Indian hunters 
used not unfrequently to bring us specimens from the same district; but we are not 
aware that the bird ever occurs to the bird-collectors of Vera Paz. 
Southwards of Guatemala we have no record of its existence. 
[Norz.—sSetophaga multicolor, briefly described by Bonaparte (Consp. Av. i. p. 312) 
from a specimen in the Senckenberg Museum said to be from Mexico, has not since 
been recognized as a Mexican bird. The adoption by Bonaparte of Gmelin’s name of 
Muscicapa multicolor seems to indicate that the bird he described was a specimen of the 
well-known Australian bird, the Red-bellied Flycatcher of Latham, which now stands 
as Petreca multicolor (Gm.), to which a wrong locality had been attached. Anyhow 
we must exclude Setophaga multicolor from the Mexican fauna until further evidence 
of its existence in that country is forthcoming. (Cf. Salvin, Ibis, 1878, p. 321.)]

Opinions have differed as to whether this genus should be used in a wide sense so as 
to include Vireosylvia, or whether it should be so restricted as to leave that genus 
to stand by itself. Prof. Baird, who closely studied these birds when compiling 
his ‘Review of American Birds,’ admitted seven genera of Vireonide, keeping Vireo- 
sylvia and Vireo distinct. The former he divided into two subgenera (Vireosylvia and 
* We follow Prof. Baird (Rey. Am. B. i. p. 322) in the arrangement of this family, the members of which 
are to be distinguished from the Mniotiltide either by the hooked bill or by the presence of a first spurious 
primary, and by the basal phalanx of the toes being more united. Prof. Baird groups the Vireonide with the 
Ampelide and Laniide, which seems to be their best location. So far as we know at present, the family has 
no near allies in the Old World, its members being restricted to the two continents of America.
