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 × 1.75. Collector, P. Seymour. Parent bird taken with the egg. 100. FISHER'S PETREL. _Æstralata fisheri._ This is a handsome bird known only from the type specimen taken off 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 × 1.55, white. 102. PINTADO PETREL. _Daption capensis._ This is the Cape Pigeon of the southern hemisphere. It has only accidentally occurred on our coast. [Illustration 069: Black-capped Petrel. Scaled Petrel.

The Least Petrel is the smallest of this family, in length measuring only 5.75 inches. Their plumage is entirely dark sooty. They have been found breeding on San Benito Island, Lower California, and they probably do on others farther south.

No nest, the egg being simply laid on the bare rock in a crevice. Size 1.00 × .75. Collector, A. W. Anthony. 104.
