296 Mr. P. L. Sclater on the Genus Hylophilus. 



In 1873 Mr. Salvin and I gave a list of the Hylophili 

 known to us in our ' Nomenclator Avium Neotropicalium.' 

 Including one first described in the appendix to that work 

 {H. muscicapinus), these were sixteen in number. But we 

 omitted H. amaurocephalus (or, I should rather say, did not 

 distinguish it from H. pcecilotis), and gave H. acuticauda 

 (No. 15) as distinct, whereas the specimen so named cannot, 

 I now think, be separated from H. hijpoxanthus (No. 7) . 



In the same year Dr. Cabanis described a new Hylopihilus 

 from Peru as H. flaviventris; and in 1880 Mr. Salvin and I 

 added an eighteenth species to the group as H. fuscicapillus , 

 from examples in Mr. Buckley's Ecuadorian collections. 



I now describe H. Inteifrons, and recognize nineteen spe- 

 cies of the genus.

 For the purpose of more easy identification, I propose to 

 consider the 19 species of the genus with which I am ac- 

 quainted autoptically, in five categories, as follows : —

* Three years subsequently (1826) Boie (Isis, 1826, p. 972) proposed 

 to use Hylophilus for a genus of Mniotiltidse, Avitli Sylvia vermivora, Lath., 

 as the type.
