Nesting.—Doctor Fisher (1906) says of the breeding habits of thisspecies on Laysan Island: The black-footed albatross is very much less abundant on Laysan than thewhite species. It colonizes the sandy beaches on the north, east, and southsides, but is not found, except rarely, on the west side. It is likewise commonon the sedge-covered slope near the beach, in the same habitat with Sulacyanops, On one or two occasions I noted them in the interior with D. immuta^MUs, U. S.

If, as was formerly thecase, the nests are systematically robbed, four eggs are usually supplied by nearly all published descriptions of eggs of the Diomedeidae they are re-ferred to in terms somewhat as follows: White, sometimes speckled orsprinkled on larger end with reddish brown (Ridgway), giving the impressionthat they resemble, on a large scale, eggs of the stormy petrel, for this may be true of some species,
