206 VIEEONID^. 



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 E. cinereiceps ^i, a simple synonym of H. decurtatus, as 

 Prof. Baird subsequently pointed out 3. 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. Salle having met with it at Cordova ^^ i9 ; 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 H. pusillus
