98. BLACK-CAPPED PETREL. _AEstrelata hasitata._

This is not a common species; it is an inhabitant of tropical seas and
has only been casually found on our coasts or inland. It is a handsome
species with white forehead, underparts and nape with a small isolated
black cap on the crown; the rest of the upper parts are blackish. It is
a native of the West Indies.

99. SCALED PETREL. _AEstrelata scalaris._

This is another rare species which is an inhabitant of southern seas. A
single specimen taken in New York State gives it a claim as a doubtful
North American species. It is a handsome bird, the feathers of the
grayish upperparts being edged with white, thus giving it the appearance
of being barred. Its eggs have only been known to science within the
past few years. Data.--Preservation Inlet, New Zealand, June 7, 1900.
Single white egg. Size 2.40 x 1.75. Collector, P. Seymour. Parent bird
taken with the egg.

100. FISHER'S PETREL. _AEstralata fisheri._

Kadiak Is., Alaska, by Mr. Fisher.

101. BULWER'S PETREL. _Bulweria bulweri._

An eastern Atlantic species which is only an accidental visitant to our
shores. They breed on the Madeira Islands where the eggs are laid in
crevices among the rocks or in burrows in the ground. Size 1.75 x 1.55,
white.

102. PINTADO PETREL. _Daption capensis._

This is the Cape Pigeon of the southern hemisphere. It has only

being simply laid on the bare rock in a crevice. Size 1.00 x .75.
