Kilda, but which the former found diffused over a great part of 
the Atlantic, east of the Banks of Newfoundland; and thirdly, 
the species of our coasts. He also indicates a fourth, which in- 
habits the Pacific ocean; but whether or not this last be in rea- 
lity a species different from those named, has not yet been de- 
termined.* 
“ When I first procured this species,” says Mr. Bonaparte, 
“I considered it a nondescript, and noted it as such; the cita- 
tion of Wilson’ spelagica, among the synonymes of the truejoe- 
lagica, by the most eminent ornithologist of the age, M. Tem- 
minck, not permitting a doubt of their identity. But having an 
opportunity of inspecting the very individual from which Wil- 
son took his figure, and drew up his description, I was unde- 
ceived, by proving the unity of my specimens with that of Wil- 
son, and the discrepancy of these with that of Temminck. The 
latter had certainly never seen an individual from America, 
otherwise the difference between the two species would not 
have eluded the accurate eye of this naturalist. I propose for 
this species the name of Wilsonii, as a small testimony of 
respect to the memory of the author of the American Ornitho- 
* Charles Bonaparte, Prince of Musignano, has recently established this 
species under the name of Procdlavia Oceanica; and assigns to it the follow- 
ing essential characters. — Tail slightly emarginate, the wings when closed 
extending more than an inch beyond its tip; length of the tarsus nearly one 
inch and three quarters (eighteen French lines.) 
We extract from his paper, in the Zoological Journal the following ob- 
servations: “In comparing this species (7-*. oceanica) to the three others 
(P. pelagica, P. Leachii, and P. Wilsonii,) it will be seen that it is the largest 
and the most varied with white of the subgenus, and that it can be con- 
founded only with P. Wilsonii, to which it bears a strong resemblance in 
shape and colour, both having the tarsi greatly elongated, the tube of the 
nostrils equally recurved, the upper tail-coverts entirely white, &c. But 
in addition to its much greater size, proportionally longer bill and tarsi, and 
lighter colour, this new species may at first sight be distinguished from it 
by its wings extending so much beyond the tail, and by the want of the 
yellow spot on the interdigital membrane, which is found in P. Wilsonii 
only.” J. H.
