92 THE NATURALIST IN BERMUDA. 
the 23rd of October, 1854, by Mr. John Darrell (son of the 
present Chief Justice), by whom it was found, in the parish 
of Devonshire, laying on the ground in a state of exhaus- 
tion. There had been a severe gale the day preceding. 
KITTIwAKE GULL (Larus tridactylus). This is one of 
the few gulls which visit the Bermudas during the violent 
westerly gales of the winter. 
BLACK-HEADED GULL (Larus atricila). A gull of this 
species, captured alive by a fisherman, in the winter of 
1851—2, was confined for some time in a spare room, but 
eventually effected its escape. 
WILson’s PETREL, or MOTHER CARY’S CHICKEN (Thalassi-

It was killed some miles distant from the shore. 
GREAT BLACK-BACKED GULL (Larus marinus). In look-

omitted in the general list of birds. On the 24th of 
December, 1851, I examined a living gull, which had been

was of a darker mottled-brown than any former specimens 
of the gull family, and measured twenty-four inches in 
length ; tarsus, 24 inches; eyes, dark brown; outer half 
of the bill, black, the mner portion, hght horn colour; legs 
and feet, clay colour; nails, black. 
I presume this to be the young of L. marinus. 
LirtLE AUK, or Common SEA Dove (Mergulus alle). One 
of these birds was captured alive on the 28th of January, 
1850, by a servant of the Rev. J. U. Campbell, at Ireland 
Island. It was in company with four or five others, on a 
piece of grass land, near that gentleman’s house. Unfor-
