*^ since the first referetice in Gray's sj-nononiy (Cat. Birds Trop. Isds., p. 9) ior Drcpaiiis {Hctiiigitathiis) eUisiana is g-iven "Ct'r/hui ulncura 

 (nee Giuel.) Vieill. Ois. dor. t. 53?". I prefer to consider that it is the reference to the exact place in the volume cited that Gray was in doubt 

 about, and that he did not intend questioning the name O-rtliia obsciira. That being the case Drcpaitis {Hemignathm) dUitaua will become a 

 svnonvni of Ht-mignathm ob^cuyus. Hence it seems that Mr. Wilson's name H. /tchh'nsh'iJii should stand.
