American spiicies are intimately related to the two Nortli American ones, 

 and may prove to be oidy climatic races of tlie same s}"jcies ; thus, en/lhroc- 

 naiiis, dray (Hand List, j). 32, No. 305) may be the intertroi)ical form of 

 fi'scufi, and cliilcnsis, I'll, and Landl). (Hand List, Xo. 314), that of coojJiri. 

 But the material at my command is too meagre to decide this.

In conseciuence of the insufficient material for working up the South 

 American species, I shall omit them all from the following synopsis of the 

 Nortli American species and races.^ 



Species and Races. 



Common CtiAH.WTKiii?. AiMt. Above bluish slate-color; the tail with obscure 

 bands of darker, and narrowly tiiiped with white. Beneath transver.^^ely barred 

 with white and pinkish-iufous ; the anal region and crissum innnaciilate white. 



* In tlic collection oC the National Museum are two specimens o( cooprri, var. gunJhichi, in the 

 young plumage. They dillei- fiom the young of var. coojKri merely in darker colors, the brown 

 markings being larger and more numerous, as well a;; deeper in tint. That their character may 

 be better understood, I furnish the following more detailed descriptions ; —
