Notes on the Petrels of Madeira and adjoining Seas. 29 
known to breed elsewhere than in the Madeiran islands and 
the Canaries. The first eggs received in this country were 
‘forwarded to Dr Frere of London, about 1850, and Mr 
Hurrell took a number in 1851 both from the Desertas ; while 
still later Godman found eggs on Chao, one of that group. In 
1889 Meade Waldo found it breeding near Orotava, in the 
Canary Islands. Bulwer’s Petrel has hitherto been recorded 
as confined to the Eastern Atlantic, but has occurred in 
Greenland and Bermuda; and Stejneger, in the Proceedings 
U.S. Museum (xii., 378), assigns to this species two specimens 
received from the Hawaiian Isiands, in the Pacific, in 1889. 
One specimen, Ilho de Cal, Porto Santo, July 1889. 
One egg, Ilho de Cal, Porto Santo, May 1889. 
Three eggs, Bugio, Desertas, July 1889. 
5. Procellaria leucorrhoa (“ Roque de Castro”), Leach’s 
Petrel, at one time considered more an American species, has 
of late been found nesting on several stations on this side of 
the Atlantic. First observed in St Kilda by the late Sir 
William Milner, it has lately been found breeding in North 
Rona by Mr John Swinburne, one of our fellows, and in 
small numbers on the Blasquet and Skellig islands, off the 
coast of Kerry, in Ireland, by Mr Ussher. I have been 
unable to discover a previous record of its breeding on any 
of the West African islands, although Mr Vernon Harcourt 
has stated that it reaches Madeira. 
One specimen, Bugio, Desertas, August 1889.

_ 6. Estrelata mollis, Soft-plumaged Petrel.—This species 
described by Gould from Australia, is also found in the 
neighbourhood of New Zealand and the Cape of Good Hope. 
I am not aware that it has been found breeding elsewhere 
than in New Caledonia, where Layard states that it nests near 
the summit of Mont Mou in that island. It has, however, 
previously occurred in Madeira, and there are, as Mr Salvin 
has informed me, two specimens in the museum at Cambridge, 
presented about thirty-five years ago by Dr Frere, who 
obtained them with other species of petrels from his corre- 
spondent in Madeira. Such being the case, and considering 
our scanty knowledge of the distribution of ocean birds, it is 
by no means improbable that a breeding place may yet be
