Pitta cceruleitorques, Dicaum sanghirense, Prionochilus san- 

 ghirensis, and Calornis sanyhirensis are described as new. 

 From Tifore and Batang Keteil only six species were obtained, 

 which, however, tend to show that these islets belong zoolo- 

 gically rather to Halmahera than to Celebes. 



29. Salvaclori's Prodromus of Papuan Ornithology. 



[Prodromus Ornitliologise Papuasise et Moluccarum. Aiictore Thonia 

 Salvadori. Pars I. Paradiseidfe. Ann. Mus. Civ. di St. Nat. di Genova, 

 vol ix. p. 188. Pars II. Colimibfe, ibid. p. 194.] 



As a prelude to his grand work on the birds of the Papuan 

 subregion, which is to be based on the extensive collections 

 of Beccari, D'Albertis, and Bruijn, Dr. Salvadori has com- 

 menced a series of lists of the species of the principal groups 

 of this avifauna, with an account of their distribution, of 

 which these two papers are the first. 



Of the Paradiseidse, Dr. Salvadori enumerates 31 species, 

 of Pigeons 90, as belonging to the Papuan subregion. Of 

 the last-named group three are described as new in the pre- 

 sent paper, namely Ptilopus zonurus, from the Aroo Islands, 

 Macropygia keiensis, from the Key Islands, and M. griseinucha, 

 from Jobi and Mysore. Gouri beccarii is established provi- 

 sionally upon the crest of a bird of this genus, obtained by 

 Beccari at Humboldt Bay.

Sirs, — In my recently published account of the zoology of 

 Persia^ {' Eastern Persia,' vol. ii. p. 128), I classed Caprimulgus 

 unwini, Hume, as a synonym of C. mahrattensis, Sykes. My 

 reason for so doing was that Mr. Hume described C. unwini 

 (Ibis, 1871, p. 406) as distinguished from all other Indian Goat- 

 suckers by the following leading characteristics : — The upper
