On some new Procellariidse. 61 



V. — On some new Procellariidre collected during a Voyage round 

 the World in 1865-68 by H. I. M.'s S. ' Magenta/ By 

 Henry Hillyer Giglioli, Sc.D., C.M.Z.S., Naturalist to 

 the Expedition, and Thomas Salvadori, M.D., C.M.Z.S., 

 Assistant in the Royal Zoological Museum of Turin. 



A FULL account of the ornithological collections made during 

 the voyage of the * Magenta/ rich in species and specimens, 

 will be communicated to the scientific world in a special Me- 

 moir, at which both of us are hard at work*. Meanwhile we 

 think it advisable to publish the following descriptions of new 

 species of ProcellariidcE, which are as important as they are 

 unexpected^ especially after the careful review of this most in- 

 tricate and difficult family by that distinguished American 

 ornithologist Elliot Couesf. 



The subject of this paper will be read at the meeting of 

 Italian Naturalists at Vicenza on the 13th of September; yet 

 as the Proceedings of that meeting will not be published for 

 some time, we have thought that an English version of the first 

 ornithological fruits of the voyage will not prove unacceptable 

 to our English friends and to the readers of ' The Ibis.^
