sionally on vegetable substances, as, on dissection, 
stomach of our specimen was found to be filled wH" 
pokeberries, (. Phytolacca decandra, L.) 
Beyond these particulars we have no positive kno"" 
ledge of the manners of our flycatcher, though VieiU 0 * 
has recorded a history of some length, taken fro® 1 
D’Azara ; but the bird observed by the latter authf f 
in Paraguay and Buenos Ayres, though closely allied 
appears to be specifically distinct from the one we af e 
describing. Yieillot has since been convinced of tbi‘ 
difference, and, in the (French) New Dictionary 
Natural History, he has separated the more souther" 
species under the name of Tyrannus violentus. I" 
colour that bird strongly resembles our Muscicap 0 
savana, but it is considerably smaller, and has different 
habits, being gregarious ; whilst the savana is a solitar/ 
bird. 
Another species, for which ours may be readil/ 
mistaken, is the Tyrannus bellulus, Vieill. which, ho"" 
ever, is much larger, with a still longer tail, differing 
also by having a large black collar extending to each 
corner of the eye, margining the white throat; and tb e 
head of the same bluish gray colour with the oth« f 
superior parts of the body ; the remaining under part 8 
being of the same colour, with a narrow brown line i® 
the middle of each feather; and by having a whitish 
line on each side of the head behind the eye, extendit'| 
to the occiput. The Tyrannus bellulus is a native 
Brazil.
