I am not acquainted with Attila bolivianus, Lafr. {Tyrannus ru- 

 fescens, Lafr. et D'Orb. ; D'Orb. Voy. p. 308). 



Next to Attila, I think, must be placed the curious type Casiornis 

 of Bonaparte, of which the earliest specific name appears to be rubra 

 of Vieillot. Its synonymy is very much confused ; but I am inclined 

 to refer Suiriri roxa, Azar. sp. 188 ; Muscicapa rubra, Vieill. Diet, 

 xxi. 457, et Enc. p. 831 ; Muscicapa hcematodes, Licht. ; Basy- 

 cephala hcernatodes, Cab. in Wiegm. Arch. 1847, i. p. 222 ; Basy- 

 cephala rubra, Burm. Syst. Ueb. iii. 87; Tyrannula rufula, Hartl. 

 Rev. Zool. 1852, p. 6, and, probably, Tyrannus thamnophiloides of 

 D'Orbigny (Voy. p. 309), to this bird. MM. de Castelnau and De- 

 ville obtained examples of it at Goyaz during their American travels, 

 and it has recently been described and figured by M. Des Murs in 

 the Ornithology of their Expedition under the name Casiornis 

 typus. Its general structure is very much that of Attila ; but the 

 bill is quite short and much more feeble, and the feet are not nearly 

 so strong. 



* Were it not that M. de Lafresnaye gives " Colombie " as the habitat of his 

 Allila flammulatus, I should be inclined to considei* his species the same as this.
