Inhabits Buenos Ayres. 



Of the numerous species of American birds which have been 

 classed in the genera Tyrannula and Elania, and which exhibit 

 much variety in the modifications of the beak, the present one has 

 that organ the most elongate ; indeed it approaches in form the 

 beak of the Sylvicoline genus Myiodioctes, though the straight 

 culmen, the comparatively short black tarsi, covered with seven or 

 eight short scuta, the slender toes and sharp claws, show the true 

 place of the bird to be among the Tyrannina. I had intended 

 making this the type of a new genus, under the name of Satrapa 

 {quasi a petty tyrant), but perceiving that M. D'Orbigny has 

 included it in his genus Suiriri, I retain that generic name for 

 the present. M. D^Orbigny admits that it differs in its smaller 

 head, more slender beak and longer tarsi from the Suiriri of 

 Azara, no. 179, which is the type of his genus ; but not having 

 examined the latter bird, I am fearful of creating a new genus 

 without sufficient reason. M. D'Orbigny's secotid species of Sui- 

 ri7'i belongs to Gould's genus Pyrocephalus, a very distinct form 

 from the present bird. 



Above olive-green, beneath bright yellow ; wings dusky, the 

 covers broadly, the secondaries and tertiaries narrowly, edged 

 with grayish white. Tail very dark brown, outer rectrices mar- 

 gined externally with whitish. A bright yellow streak from the 

 nostrils over the eye. Lores and ear-covers dusky olive. Beak 

 and legs black. 



Total length 6| inches ; beak to gape 8 lines, to front 6 lines, 

 width 2^ lines, height 2 lines ; wing ^\ lines ; medial rectrices 

 2h inches, external 2f inches ; tarsus 9 lines ; middle toe and 

 claw 8| lines, hind ditto 6 lines ; outer toe slightly longer than 

 the inner.
