M. Buonaparte on Procellaria oceanica, 89 



Art. X. Supplement fo " an Account of four Species 

 of Stormi/ Petrel;''' (Thalassidroma, Vigors\), By 

 C. L. Buonaparte, Prince of Musignano^ <^c. 8^c. 



In the above named paper I only established three of the 

 species, and merely indicated the fourth on Temmitick's authority : 

 the existence of the latter, as distinct from my P. Witsonii^ 

 became every day more doubtful ; and I had to regret, in my 

 " Obs. on the Nom. of Wilson's Ornithology," not being able to 

 settle that important point. It is with great pleasure that I shall 

 now put this species on the same footing with the others, under 

 the name of 



4. PllOCKLLARlA OCEANIC^\, nob. 



Tail slightly emarginato, the tmngs when closed extending 

 more than an itich beyond its tip ; length of the tarsus nearly one 

 inch and three quarters (18 French lines).

 Museum in Antwerp. Probably J the P. oceanica of the original 

 drawings of Forster, icon. 12, (which I have not seen) ; for which 

 reason I have given that name to my species, although I have £^s- 

 certained that the bird that bears it in Temminck's celebrated 

 collection is but a bad specimen of my P. Wilsonii. As for the 

 Petrel echasse of Temminck it must l^e erased from the list of 

 species ; and it is most probably established partly on the above-

+ This group has already been established in niy Systematic Catalogue of 

 th« Birds of the United States of North America ; but having given it no 

 name, it is w^ith pleasure that I am here able to adopt the scientific one applied 

 by the above-named English Ornithologist. 



t At all events Forster's species P. oceanica, not having been published, 

 cannot interfere with mine. I have besides no doubt of their identity.
