One specimen of this splendid Rail, which would appear to 

 be exceedingly rare in collections. At present it has only been 

 met with on the Rio Boutry by Heer Pel, and in Aguapim by 

 Riis, while, according to Dr. Hartlaub, there is a specimen from 

 the Gaboon in the Paris Museum.

XVI. — Note on the species of the Genus Hirundinea, belonging to 

 the family Tyrannidse. By P. L. Sclater, M.A., Ph.D., 

 F.R.S., Secretary to the Zoological Society. 

 (Plate V.) 

 In the second part of his lately-published * Ornithologie Brasi- 

 liens'*, Herr von Pelzeln has correctly shown that two. very dis- 

 tinct species of birds have usually been confounded under the 

 name Hirundinea ferruginea. One of these, the true H.ferru- 

 ginea, inhabits the Guianan region, whilst the second, which Herr 

 von Pelzeln (following Prince Max.) calls H. rupestris, is its re- 

 presentative in South-eastern Brazil. Professor Reinhardt has 

 recently most kindly forwarded to me for examination a skin of 

 what appears to be a third representative species of this peculiar 

 genus of Tjjrannid(B. This specimen was obtained by Professor 

 Reinhardt, during his voyage round the world in the ' Galatea,' 

 from Don Mariano Rivero, of Lima, along with the beautiful 

 Tanager [Iridornis reinhardti^ which I figured and described 

 in 'The Ibis' for 1865, and was stated to have been received 

 from Eastern Peru. I was at first inclined to agree with Pro- 

 fessor Reinhardt in regarding this bird as undescribed; but after 

 carefully perusing Azara's original description of his " Suiriri 

 rooco ohscuro " (Apunt. ii. p. 129), I feel nearly convinced that it 

 is the same as the Paraguayan form upon which Vieillot has 

 founded his Tyrannus bellicosus.
