No. 95. STORM-PETREL. (Procellaria pelagica.) 
This bird, often known as ‘‘ Mother Carey’s Chicken,” is strictly 
pelagic in its habits, seldom coming to shore except during the breeding- 
season. It is generally distributed throughout British waters, frequents 
low islets and other suitable situations, and is common off the coasts 
of Scotland and Ireland. During severe storms it is sometimes driven 
inland, and is occasionally found far from the coast. The food con- 
sists of small fish, crustaceans, molluscs, and fatty matter floating on 
the surface of the ocean. A single white egg, faintly dotted with rusty 
brown, is laid at the end of a burrow or beneath stones, often on the 
bare soil, but sometimes on a slight nest of dry grass-stems. Though 
eggs are sometimes found as early as the end of May and as late as 
September, incubation usually commences about the middle of June, 
and lasts for thirty-five days.

No. 96. LEACH’S FORK-TAILED PETREL. 
(Oceanodroma leucorrhoa.) 
This species, restricted to the Northern Hemisphere, is met with 
off the coasts of Great Britain, occasionally in numbers, duving the 
autumn and winter months. It is known to breed on the St. Kilda 
Group, on North Rona and other islands of the Outer Hebrides, as 
well as on the Blaskets, off the south-west coast of Ireland. The food 
consists of small molluses, crustaceans, and greasy matter found floating 
on the sea. The nest is made at the end of a burrow or in a hole of 
some kind; and a single white egg, zoned and freckled with minute 
rusty dots, is laid in June. Both birds take part in the incubation.

No. 97. PUFFIN. (Iratercula arctica.) 
Vast numbers of the “Sea-Parrot” or ‘‘ Coulter-neb,” as it is often 
called, breed in the cliffs and grassy slopes on many parts of the coast- 
line of the British Islands. In the end of August, when the young 
are ready to follow their parents into the water, they leave the coast 
for the open sea, where they pass the winter, returning to their 
breeding-places in March or April. The single dull white egg, faintly
