CRITICAL NOTES ON PROCELLARIID^. 



By OSBERT SALVIN, M.A., F.R.S., &c. 



Part II. The new Species of Petrels obtained during the Voyage of the Italian 



Corvette 'Magenta ' round the ]Vorld. 



In the year 1869 Dr. H. H. Giglioli and Count Salvadori described in ' The 

 Ibis ' five species of Petrels, skins of which formed part of the collections 

 made during the voyage of the ' Magenta ' by the first-named gentleman, who 

 occupied the post of naturalist to the expedition. These descriptions were 

 afterwards published in the 'Atti della Societa Italiana Sc, Nat.' xi. pp. 450-458. 

 Though described with great care by the authors of these papers, such is the 

 difficulty surrounding the species of this family that ornithologists have been 

 scarcely able to do more than grant them a nominal place in the system. 

 Thinking that an important step might be established in the knowledge of 

 these birds if figures of them were published, I wrote to Count Salvadori 

 asking for the loan of the type specimens for this purpose — a request he most 

 obligingly acceded to. From these type specimens the five plates accom- 

 panying this paper have been drawn by Mr. Keulemans. 



Before proceeding to give a detailed account of the five species described 

 by the above-named Itahan naturalists, I must say that though I have searched 

 the British Museum and the galleries of the Museum of the Jardin des Plantes 

 in Paris, Mr. Gould's collection, as well as Mr. Godman's and my own, I have 

 not succeeded in finding representatives of any one of these species. More- 

 over my present knowledge of the literature of the Procellariidse leads me 

 to believe, with Dr. Giglioli and Count Salvadori, that the species are really as 

 novel as they supposed them to be when they described them
