II An. Cnha. and Florida Keys? (Peihaps Hahamas. ) 



This species lias ji elt)se external ri'seniltlance tn /*. ,s/'/*/.s, tnr \vlii( li it lias 

 ustialiy ])een niistiikeii. It is of nearly tlie same si/c, Imt the feet are dispro- 

 jiortionately smaller and weaker; ^\hile the uinus ;ire shorter, the tail is as 

 lonLj ami more deeply forked ; the feathers eonsi(h'ral>ly narrower, and more 

 attenuated (the outer .4(1 wide, instead of .4(>j. The <'olnrs ahove are more 

 hrilliant, and exteinl more over the irreati'r wiiiLT-eoverts and lining of wiims, 

 while the ([iiills and tail-feathers have a richer ulos.-. of )»iir]dish, ehaimin*,' 

 to ufrecnish. An apparently .uood dia^nostie feature is the eoneealed juire 

 white of the feathm's ahont the anal reunions, replaced in .suhis hy grayish, 

 rarely api>roximatinj.!; to whitish. 



A Proijiie collected hy Mr. Wrij^ht, at Montt^ Verde, is didler in color than 

 that from IJeniedios, hut has still more concealed white helt»\v, in the median 

 ]M)rtion, not tnly of the anal feathers, hut of th(jse of the entire crissmn and 

 of the hell,. A female hird, which I presume t(j he the same species, can 

 scarcely he distin,i,niished from the female (d" dDhtinirensla, exce]>t in the 

 hrownish shafts of the lon;^'er crissal feathers, and an almost imperceptihle 

 tin«ije of hrownish in the webs of the same feathers. It is almost exactly 

 like the 1*. Iimojnfitrr of Mexico and Central America. 



This species is inclmled in the North American fauna in consequence of 

 the capture of a specimen (No. l(),:WiS ^ jin:, May IS, 18r>Sj at t'ap(^ Flor- 

 ida, which is with scarcely a doiiht referahle to it. This specimen is a 

 young male in its second year, so that it is ditlicult to ascertain positively 

 its relationship to the two allied s])ecies ; Vmt as it agrees perfectly in its pro- 

 portions with ('ri/pto/aurf, ixnd its ]tlumaue differs from the corres])oiiding one 

 of suhiii in essential respects, we have little hesitation in referring it to the 

 former. 



Nothing distinctive is recorded as to the habits of this bird.
