Rio Negro, kindly lent by the authorities of the Vienna Museum, and did not 

 look up the original description in the Sitzungsberichte der Akademie der 

 Wissensch. Wien sx. 1856. p. 157, this periodical not being in the Tring library. 

 I have, however, lately had the opportunity of consulting this work, aud find 

 that Pelzeln did not describe Natterer's specimens from the Rio Negro, but 

 suggested P. a/jiitis as a new name for Trochilus mperciliosus Wied,* which he 

 considered to be different from the true T. mperciliosus of Linnaeus. As Wied's 

 description is undoubtedly referable to P. pretrei (Del. & Less.), Pelzeln's term 

 affinis becomes a synonym thereof, while the species with white under tail-coverts, 

 P. superciliosus anct., is to be called P. fraterculus Gould. 



At present I am not in the position to say whether P. moorci, P. ochracei- 

 ventris, aud P. boUtianus are more nearly related to P. malaris or to P. fraterculus, 

 aud must leave the final decision of this intricate question to fatnre investigations.

was obtained in Bolivia by Bridges ; cf. Monogr. Trochilhl. i. pi. 22).

This series is perfectly ideutical with two topotypical Bolivian skins, collected 

 near Salinas, Beni River, by Mr. Maxwell Stuart. The edges to the rump feathers 

 are hoary, those of the upper tail-coverts more whitish. I examined, some years 

 ago, the specimen obtained by Natterer, and lately I have also compared one of 

 D'Orbigny's examples (from Guarayos) in the Paris Museum. Both belong to 

 the present species. 



P. hispidus is new to the Brazilian avifauna.

 Cf. supra, p. 74.

 bill 31| mm. 



These specimens agree perfectly with those from Tefie' in coloration, but 

 have slightly shorter wings. P. philippii thus appears to be widely distributed 

 over Brazilian Amazonia, and the original locality, Bolivia, was, after all, 

 perhaps correct. The rauge of the species is, according to our preseut knowledge, 

 as follows :
