OCEANODROMA LEUCORRHOA. 443 
[§ 5134. Seven.—Desertas, 1850. From Dr. Frere, 1861. 
These, as the Doctor's tickets upon them shew, were part of the second lot 
of eggs received by him, and were given to me by him when he discontinued 
collecting. |

From Sefor Gomez, through Mr. Dresser. | 
OCEANODROMA LEUCORRHOA (Vieillot). 
LEACH’S PETREL. 
§ 5136. One.—St. Kilda, June, 1847. From Mr. Graham, of 
York. 
Mr. James Tuke wrote me word that Graham had been in Scotland 
with some gentlemen, and among other eggs had met with that of 
Wilson’s Petrel. In consequence of this mistake I ordered one, but 
on its arrival not only was it a Leach’s Petrel’s, but it was cracked 
from the box being too small. I mended it as well as I could, and 
as Mr. Tuke kindly offered, I sent it back accompanied by one of 
mine, which I had obtained from M. Hardy [in 1846], and resembled 
it in every particular, proposing that Graham should retain my 
perfect specimen and send me back his St. Kilda one, to which he 
agreed, so that I have Leach’s from two distinct sources. Graham 
was with Mr. Henry Milner, who says to me [that they got] “ Leach’s 
Petrel with the eggs in St. Kilda. It breeds earlier than the common 
Storm-Petrel, but in the same sort of place, and in one instance I 
found them breeding in company —at least their burrows were 
contiguous. I could only obtain one Storm Petrel’s egg, as the others 
had not commenced laying on the 10th of June.” ; 
§ 5137. One.—From M. Hardy, 1847. 
These eggs—Mr. Henry Walter had another at the same time— 
M. Hardy informed me he had with the birds, from (I think) Frée, 
and were of course beyond all doubt. The one I had last year, which 
was exactly like the St. Kilda specimen in my cabinet [§ 51386], I 
exchanged for it. This is a longer egg. )
