out gloss, and generally with a belt of minute 
dark red spots at the large end. The Storm Petrel 
disappears from all its breeding places after the 
young are reared, and seems to reside on the open 
sea during winter. It has a buoyant and gliding 
flight, floats lightly on the water, and swims with 
ease, letting dcwn its feet occasionally when 
skimming over the waves. It has even been 
imagined, like others of this genus, to walk on the 
sea, whence its name Petrel or Little Peter.

THALASSIDROMA WitsonI, Zemm. 
This species, named by the Prince of Canino in 
honour of the celebrated Scoto-American Orni- 
thologist, is said to breed on various parts of the 
coasts of North America, and to occur plentifully 
on the Atlantic ocean. It is admitted in the Bri- 
tish list as an occasional visitant. It breeds on 
some small islands, situated off the southern extre- 
mity of Nova Scotia, which are formed of sand and 
light earth, scantily covered with grass, where 
it forms burrows to the depth of about two feet, 
in the bottom of which, in a nest, made of a few 
bits of dried grass, scarcely deserving the name, it 
lays a single white egg. The egg, measuring an 
inch and a half in length, is almost equally round 
at both ends.
