 the habitually elaborate and exact method of the distinguished 

 author. The U.S. National Museum coutains examples of 

 all the species except C. hypopoUus, C. rnfiventris, and C. 

 tricolor (" the two latter being of somewhat doubtful status "),

25 . Salvadori on the Ornithology of Papua and the Moluccas. 



[Ornitologia della Papuasia e delle Molucclie, di Tommaso Salvadori. 

 Parte seconda. 4to. Torino : 1881.] 



In our notice of the issue of the first volume of Prof. Sal- 

 vadori^s work (Ibis, 1880, p. 255) we gave a short account 

 of this great undertaking, and of the extensive materials upon 

 which the author had based it. It is with great pleasure that 

 we now chronicle the issue of the second volume, and are 

 able "to announce that the third, which will complete the 

 work, is far advanced in preparation. 



In the present volume the numerous Passeres come under 

 consideration, and swell its size to 706 pages, which treat 

 of about 470 species. The plan pursued is exactly the same 

 as that of the first volume. Every species is fully and fairly 

 described; its complete synonymy is given ; and a detailed list 

 o£ the specimens examined from various localities over which 

 the species is spread is added. 



As many of our readers are already aware, the Eoyal 

 Academy of Sciences of Turin, which published Prof. Salva- 

 dori's first volume as one of their ' Memorie,^ have unfor- 

 tunately not found it convenient to adopt the same course as 

 regards the second. The author is therefore compelled to 

 appeal to his brother ornithologists to subscribe for copies of 

 the second and third volumes of his most meritorious work, 

 in which, we are sure, he will receive every possible support. 

 Pew special works of the present day have been so well planned 

 or so thoroughly carried into execution as Salvadori^s ' Orni- 

 tologia della Papuasia.'
