NEW FORMS OF SOUTH AMERICAN BIRDS AND PRO- 

 POSED NEW SUBGENERA. 1 



BY CHA.RLES B. CORY. 



Xenicopsoides subgenus nov. 



Characters. — Similar to Xenicopsis Cabanis, but with much less gradu- 

 ated and relatively shorter tail (tail less than -$ of wing), relatively shorter 

 tarsus and plain under parts. (Type Anabazenops variegaticeps Sclater) . 



This new subgenus includes the following: Anabazenops varie- 

 gaticeps Sclater; Anabales temporalis Sclater; Philydor montanus 

 Tschudi; Anabates striaticollis Sclater; Xenicopsis anxius Bangs 

 and Philydor venezuelensis Hellmayr. 



Euphilydor subgenus nov. 



Characters. — Similar to Philydor Spix, but shape of bill different, the 

 terminal half of under mandible (gonys) being decidedly elevated (nearly 

 as in Xenicopsis) and the end of the culmen more curved. (Type Philydor 

 lichtensteini Cabanis and Heine). 



1 The writer does not sympathize with the increasing tendency to elevate subgenera 

 (which are often based largely on color characters) to genera, unless diagnostic structural 

 characters are also indicated. A well-marked and useful subgenus may represent a 

 questionable genus.
