T\w lu't'cssitv of roinoving the typo oi thi.s gcnu.s from I*ljnlo. with 

 which it has usually been associated b}^ American authors, has long 

 been recognized by European ornithologists. Bonaparte placed it in 

 Kii-nerki {=2Iel():cO')u^)\ Messrs. Salvin and Godman have referred it 

 to EmhemagTa (i. e., Arreniono2)S), while Dr. Sharpe has put it in 

 Afhij>pfr.'<. Neither Salvin and Godman nor Sharpe give any reasons 

 for their action, though evidently it was a certain reseml)lance (by no 

 means a close one) in coloration between Fr'nKjiUa clihirniui and the 

 species of Arremouoj)^ and Atlapet<>< which induced them to do so. 

 If structural characters are of any value, however, F. vldonira is far 

 more out of place in either of these two genera than in Pipilo^ while 

 even in coloration, as above stated, it is not so distant from the latter 

 as might be supposed.^
