LARIDA. 627 
The Storm Petrel usually places its eggs in a hole 
in the crevice of a rock or in a rabbit-hole. Its nearest 
breeding station to these parts seems to be at the 
Scilly Islands: it also breeds in considerable num- 
bers on a little rocky island in the Race of Alderney. 
Mr. Sanford gave me a curious description of a 
Storm Petrel’s breeding station, which he had 
visited, on a small rocky island off the coast of 
Galway, called Hii Island: on the top of this island 
there is a small lake, on the banks of which is an 
ancient building, like the domed hut of an Esqui- 
maux: the walls of this hut are very thick, nearly 
five feet, and in the holes in these walls the Storm 
Petrels bred in considerable numbers, but on no 
other part of the island, neither in the crevices in 
the rocks nor in holes in the ground. 
The Storm Petrel has the same tubular nostrils 
at the base of the upper mandible as I have before 
mentioned. The bill is black; irides dark brown; 
the head, neck, back, wings and tail are sooty black ; 
the outer edges of the tertials white; upper tail- 
coverts white; chin, throat, breast, belly and under 
tail-coverts sooty black; sides of the vent white; 
legs, toes and webs black. This is a smaller bird 
even than the Forktailed Petrel, the whole length 
being not quite six inches. The young birds of the 
year are not quite so dark in colour; the edges of 
the wing-coverts are rusty; there is no white on the
