phaga. We have therefore to choose one or other of these 
relations for connecting Sylvicoln with Zosterops : and as 
Dumecola shows a much stronger resemblance to Zoste- 
rops, than does Setophaga (which, indeed, seems to have 
none), we ground our decision on this especial point of 
argument ; more particularly as Setophaga, although it 
seems to have no intimate connection to Zosterops, has 
yet (in some undescribed species before us) a most pal- 
pable affinity to Trichas. The situation of all these 
groups will be apparent in the diagram we have already 
given of the Parianm (p. 57-)- admitting, for the 
sake of argument, that Dumecola had nothing to do with 
the present group, and that it is ultimately proved to 
belong to the true Tgrannulce (an affinity which is barely 
possible), still even this would not effect any change in 
the situation of Setophaga, for this especial reason, that 
this group is unquestionably related most intimately to 
Trichas, — an affinity which, if once violated, throws the 
whole division of this otherwise most teautifully ar- 
ranged subfamily into perfect disorder and confusion. 
(70.) iV''e enter among the true warblers (Sglviante) 
by the genus Culidvora, or gnat-snappers, — a group of 
delicate little birds, having one half of the bill, as in Se- 
tophaga, depressed, and the other half, as in Sylvia, com- 
pressed. This group is limited to America ; and so 
much do their manners resemble those of the flycatchers, 
that Wilson describes the principal speciesas aMuscicapa. 
Prom these we pass to the pre-eminently typical group of 
the whole family, the restricted genus Sylvia, in which are 
the golden-crested (Jig. 134.), willow, and wood wrens, — a 
popular, although by no means 
a correct name, inasmuch as 
all these birds are typical ex- 
amples of the whole family : 
this passage is effected by 
certain Setophagai of Brazil, 
which, by their size and 
^ golden coloured crests, so much 
resemble those of Europe, that the depression of their
