NOVITATES ZOOLOGICAE XXI. 1914.

Mr. Cha))man, iu describinsj this bird as new, was no doulif misled by Dr. Allen, 

 who, in his revision of the Genus Elainea,* had placed E. parvirosfris Pelz 

 among the synonyms of ?2. alhiceps, from which it is, however, specifically distinct. 

 I have e.xamined altogether 57 sjiecimens of E. jmrv/'rostris,a,ud although there 

 is a certain amonnt of individnal variation, as in other species of Elaenia, I am 

 unable to separate any local races.
