Messrs. Salvin and Elliot on the Trochilidae. 5 



placed it as a synonym of P. malaris, which is itself a synonym 

 of P. super ciliosus. Mr. Gould, in the first volume of the ' Tro- 

 chilidae/ described a bird from Cayenne and the neighbouring 

 countries as P. fr at er cuius, stating that its differences from P. 

 superciliosus consist in its smaller size and its somewhat more 

 curved bill. We trace this small bird into New Granada and 

 the Upper Amazon, from specimens before us ; and we cannot 

 separate it from P. superciliosus, the differences being such as 

 belong to individuals and sex, rather than such as can be deemed 

 specific. In 1860 Cabanis and Heine made some radical 

 changes in the synonymy of this and one other species of this 

 genus. They associated P. pretrii of Lesson and De Lattre, 

 which is the Trochilus superciliosus of Prince Maximilian, with 

 the true T. superciliosus of Linnaeus, giving Brazil as its ha- 

 bitat ; but we can discover no authority for saying that the 

 Linnean bird has ever been found there. For the Cayenne 

 bird, which is the true superciliosus of Linnaeus, they use the 

 name malaris of Nordmami. These conclusions Mr. Gould 

 unfortunately adopted in his ' Introduction to the Trochilidae/ 

 the synonymy having been previously almost correctly given in 

 the text accompanying his plates. 



We notice, on comparing Cayenne with Upper Amazon and 

 Ecuadorian specimens, that many of the former have dark- 

 coloured throats, but on the other hand some have the ordi- 

 nary pale-coloured gular stripe. This would seem to show that 

 this character cannot be relied upon as specific. 



We have examined the following specimens : — 



Cayenne: two, Mus.P.L.S.; one,Mus.D.G.E. {ex Deyrolle) . 



Para : three, Mus. J. Gould. 



Pebas: one {Haux well), Mus. D.G.E.; two {id.), Mus. S.&G. 



Peruvian Amazon: one {Bartlett), Mus. D. G. E. 



Ecuador : one {ex J. Gould), Mus. D. G. E. Canelos : one 

 {Buckley), Mus. S. &. G. 



Columbia: one, Mus. P. L. S. ; two {Bourcier), Mus. D. G. E.
