Tn the above named paper I only established three of the 

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

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

 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 i)leasure that I shall 

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

 the name of

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

 reason I have given that name to my species, although I have as- 

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

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

 Petrel icliasse of Temminck it must be erased from the list of 

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

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

 the Birds of the United Slates of North America ; but liaving given it no 

 name, it is with pleasure that I am liere able to adopt the scientific one applied 

 by the above-named English Ornithologist. 



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

 cannot interfere with mine. 1 have besides no doubt of their identity.
