XURTII AMERICAN BIRDS. 



•IS it l)eloiigs to a difreroiit siiliiiiniily. At present three species are known, 

 i-wo of them recently described. Unless Z. yucatancnsis proves to be a 



1180 



Zenaiilum carolinensis. 



hybrid between Zcnuida amahilU and Zcmndura carolinensis, it may be 

 expedient to nier^e Zcnuida and Zcnaidum into one, since, if yucaknsis 

 pro re to be u perniaiieiit form, the additional pair of tail-feathers is all that 

 is left to characterize Zawidiira ; and when we consider that the wedge-tailed 

 ffaliaius j)da;jirtis has fonrteen tail-feathers, while the round-tailed species 

 have (.nly twelve, it seems reasonable to consider the diflerence as merely 

 specific in this case also. 



A. Secondaiifs l)i-oiully tippud with Avliito.

1 Zamu/um ,/Ha,l,nu'„s,:i, Lawi;. Ann. N. Y. IX, 1869. This bird is .so .■xactly inteniicdiatp 

 betwpiMi the Z. caroUnmms and Zcnaida amnhilis, as to lead us to stroufjlv susix-ct it is a 

 l.yhrid hctwccn tlic two. With tli." Z. am.li„n,sh it a-rccs only in ,H..s.scsshi<; fourteen tail- 

 l.athei.s ; the coloration and size an.l shape ol' the hill hcins exactly those of Z. anmbilis, 

 wlnle the tnil-fcalliers arc internie.liate in length and .shape between those of the two species. 

 The colors diller from those of Z. .imubilis only in bcinj? of a just appreciably lighter shade, there 

 hemgthe same broad white tip to the secondiuies, lailliant steehblue suhauricular spot, and 

 •h'cp reddish ciissuMi, characterizing the Z. oiwihili.s, as .listiuKuishiMl from Z. mmlhinm,. 



• Zni,n,l„ra ,im,is,m!, Lawi:. Aim. \. V. Lye. February, 1871, 17. A very distinct species, 

 remarkable for its lar^e, yery lonj,', and nncli d.'iiresscd lull, and dee|. feiruginou.s, in.stead of 

 limkish-vinaecous, lower Jiarts. The specimens are unfortunately uU young birds, thouL'h they 

 ■nc hdly ^'rown.
