Fam. Tyrannise. 



Of the great family Tyrannidse forty well-determined species were 

 obtained by Mr. Bartlett, besides skins of several others not de- 

 terminable from imperfection or other causes. Most of them are 

 widely distributed ; but several are peculiarly Upper-Amazonian, viz. 

 Muscisaxicola Jluviatilis, Todirostrum chrysocrotaphum, Euscarth- 

 mus spicifer, Serpophaya hypoleuca, Myiozetetes sulphureus, and 

 Muscivora castelnaudi (if distinct from M. reyia). The occurrence 

 of the North-American Kingbird {Tyrannus pipiri) so far south is 

 of interest, as is also the meeting with Tyrannus aurantio-alro- 

 cristatus so far north.
