Kill ratliHr Btnall ; nnntriiri oval, nuperlor, niArginod Itohlnd, but HcarcKljr 

 latfrully hy lueuibraue, but not at all overhung ; tliu axeii of the outlinii cod- 



oonounled white, but dark gray In the middle, neiieath wlilte, all tlio 

 fttatht^rH dark pluinlxtouH at baHH ; the breaHt with a grayiith Hhade acromi it 

 owing to the fact that tht« fuatherH there are grHyiHh-brown, rather narrowly 

 t^ilged with white, leHH pure than on the throat, and allowing this gray to ttliow 

 through as well as among the whitish. The urissal feathers immediately 

 ItHhind the anus are white; the longer ones are white, or grayish-white at 

 base, and then blackish, glossed with steel blue at the eml. The axillarHamt 

 inside of wlng< are brownish-gray. The sides of body under the wiugs are 

 ellghtly soiled with gray. Hill black ; feet apparently llesh color. 



(No. 21,03!l ) Total length, 1).0(»; wing, 3.J)(l; tail, a.-'if), i>erpendiculardeiith 

 of fork, .40 ; (iiu^vt^nce of (|uills, 1.U3 ; length of bill from forehead, .40, from 

 nostril, .19, along ga^ >, Jtl, width, .40 ; tarsus, JtO ; middle toe and claw, .W, 

 claw alone, .16 ; hind toe and claw, .38, claw alone, .17. 



This species appears quite distinct from the njnnoif.um of Brazil, in slightly 

 larger size, much larger bill and f^et, absence of white in the interscapular 

 ffathers, and of bluish gloss on the lesser wing coverts ; lighter color of baHcs 

 of feathers below ; grayish breast, the feathers less tipped with white ; wliito 

 feathers behind the anus, and whitish bases of the rest ( f crissal feathers (not 

 black) ; lighter tibiae, etc. The lateral tail feathers are rather narrower, and 

 not acuminated or attenuated at the end — the outline of inner web towardB 

 the end being convex, not concave. 



It is a (juestion wliether this is not the real U. cynnoleuen, of Vieillot, as 

 based on Azara's description. If ao, the Brazilian cyunoleuca will take for 

 name one of its synonyms.

I am by no means satisfied that the bird of Brisson is the present species,
