These birds were found quite abundant at Cape St. Lucas, Lower California, by Mr. Xantus, by whom a number of their nests and eggs were obtained. The following brief memoranda in regard to a few of these nests will serve to show their general position:—“Nest and two eggs, found May 20, about ten feet from the ground, woven to a small aloe, in a bunch of the _Acacia prosopis_. Nest and two eggs, found May 22, on a dry tree overhung with hops. Nest and one egg, found May 30, on an acacia, about fifteen feet from the ground. Nest with young, found on an aloe four feet high. Nest and eggs, found on a moss hanging out of a perpendicular bluff, on the sea-coast. Nest and eggs found on a _Yucca angustifolia_, on its stem, six feet from the ground. Nest and two eggs, found in a convolvulus, on a perpendicular rock fifty feet high. Nest and three eggs, found on an acacia, twenty-five feet high.” The eggs of this species vary somewhat in shape, some being obtuse and more spherical, others more pointed and oblong. They vary in length from .92 to .88 of an inch, and from .68 to .65 of an inch in breadth. They have a clear white ground, marbled and blotched with large dashes, dots, and irregular zigzag lines of purple, brown, and black, chiefly disposed around the larger end. In those where the spots are more diffused they are blended with obscure blotches of a faint lavender. Icterus baltimore, DAUDIN. BALTIMORE ORIOLE; GOLDEN ROBIN; HANG-NEST. _Oriolus baltimore_, LINN.
