312. Tachyphonus Rubescens. Sw. We have long ago proposed to 



remove this from the genus Tachyphonus. {See Zool. Journal, 



No. 10.) 



314. Golden-crested Tanage)\ This we believe to be the species 

 already described on the last page, as Tachyphonus Suchii. Sw. 



318. G. Tyrannus. Nearly all the tyrant Flycatchers, and certainly 

 the most powerful species, being natives of Brazil, we had an 

 opportunity of ascertaining their habits from personal observation. 

 We are unacquainted with any species that prey either upon 

 small birds, or carcasses. The Tyrannus Sulphuratus, in its 

 general size, and particularly in the strength of its bill, exceeds 

 all others yet known. Its principal food is insects, but we have 

 more than once witnessed this bird dart upon small lizards, 

 which are swallowed whole. 



Regarding the numerous species here arranged among the 

 Tyrants, it may be observed, on reference to our monograph 

 of this group,* that several species are clothed nearly in the 

 same colours ; and that their chief specific distinctions rest on 

 the different formation of their wings. Now as these characters 

 have been entirely overlooked by all the authors here cited, it 

 becomes next loan impossibility to discover the species intended 

 to be described. We have elsewhere considered the Lanius 

 Vengata, as the type of a sub-genus. (Zool. Journal, No. 10, 

 Sept. 1827.) 



331. Our Muscicapa Labrosa we cannot discover to have the affinity 

 here stated. To our apprehension it belongs to the Ceble- 

 pyrinae. 



332. We have endeavoured (Zool. Journal, No. 11) to point out the 

 distinctions which separate the whole of the American Fly- 

 catchers from those of Europe, Africa, and the Asiatic range, 

 and to this group, so distinguished, the sub-generic name of 

 Tyrannula has been applied. The Muscicapa Barbata, and
