 than those of T. sulphuratus, but less robust.

There is so little apparent difference between this bird and the 

 Yellow-crowned Fly-catcher of Latham, figured at pi. 453 of the 

 Planches Enluminees, that they may probably belong but to one 

 species. The size of the bill is only inferior to that of T. Pi' 

 tangua. The specimen here described came from Brazil, where 

 the species is not common. 



Sp. 4. Tyrannus crinitus. 



T. olivaceus, infra sulphuratus; jugulo pectoreque cinereis; remigum pri- 

 morum margine, rectriciumque superficie infenori ferrugineis. 



Gray olivaceous, beneath sulphur-yellow; throat and breast cinereous ; mar- 

 gin of the greater quills, and under side of the tail, ferruginous. .

 Muscicapa Ludoviciana. Ind. Orn. 2. p. 486. 



Head with an incumbent crest ; upper plumage dull olivaceous ; sides 

 of the head, ears, throat, and breast, light slate colour, which then 

 changes into a pale sulphur-yellow ; wings blackish, the two series of 

 covers, and the margins of the lesser and scapular quills bordered with 

 yellowish white, while the greater quills, both externally and internally, 

 are margined with ferruginous. Tail even ; the outer webs brown, the 

 inner ferruginous ; on their under surface this last colour predominates : 

 bill brown ; tarsi slender, black. 



There is little doubt that Dr. Latham has inadvertently de- 

 scribed this bird under two names. M. Vieillot concurs in this 

 opinion, but instead of retaining the original name of Linnaeus, 

 has substituted that of Latham. Wilson has given an interesting 

 account of its manners, and has figured it most correctly. 



Inhabits North America. 



Total length 8£, bill 1, wings 4, tail 3-J, tarsi T §. 



Sp. 5. Tyrannus calcaratus. Sp. Nov. 

 Spiny-footed Tyrant. 

 T. olivaceo-fuscus, abdomine fulvescente; genibus spinuliferis. 



Olivaceous brown, tinged on the body with fulvous; knees armed with small 

 acute spines.
