206 VIREONIDZ. 
In Central America all the members of the genus belong to the lowland forests, none 
being found more than 1500 feet above the sea. 
The species of Hylophilus are shorter and stouter than those of Vireo, having short, 
rounded wings, and a narrow tail of about the same length. The bill is more conical 
than in Vireo, the culmen being but slightly curved towards the tip. The legs are 
stronger and longer in proportion than those of Vireo, and the hind toe longer.

This was one of the birds described by Bonaparte in 1837 from a specimen obtained 
by Col. Velasquez de Leon during his fortnight’s tour in Guatemala, in which country 
we have since found it to be common, but only in the low-lying forest country of 
Northern Vera Paz, whence our bird-hunters used to obtain us a plentiful supply 
of specimens, and where we ourselves observed it in February 1862. These were 
described under the name of H. cinereiceps", a simple synonym of ZH. decurtatus, as 
Prof. Baird subsequently pointed out®. This Hylophilus doubtless also inhabits the 
forests bordering the Pacific coast, as Mr. Lawrence includes it in his list of Prof. Sumi- 
chrast’s Tehuantepec collections®. Northwards of this we have only one record of its 
existence, M. Sallé having met with it at Cordova! ™; but southwards the above list 
of localities shows that it is found in all suitable localities as far as the line of the 
Panama railway. Specimens from the last-named district were named HZ. pusillus
