Seiurus ludovicianus (I, 287). Mr. E. Ingersoll met with the nest and eggs of the Large-billed Thrush near Norwich, Conn. The nest was sunk in the ground, in some moss and in the rotten wood underneath the roots of a large tree on the banks of the Yantic River. It was covered over, except just in front, by the roots. The nest was 2½ inches in internal diameter and rather shallow, and was somewhat loosely constructed of fine dry grasses and little dead fibrous mosses. About the nest, but forming no part of it, were several loose leaves. These were chiefly in front of the nest, and served as a screen to conceal it and its occupant. The nest itself was placed under the edge of the bank, about ten feet above the water. The eggs were four in number and were quite fresh. Unblown, they have a beautiful rosy tint, the ground-color is a lustrous white, the egg having a polished surface. They are more or less profusely spotted all over with dots and specks, and a few obscure zigzag markings of reddish-brown of two shades, and umber, with faint touches of lilac and very pale washing of red. These markings are much more thickly distributed about the larger end, but nowhere form a ring. They resemble the eggs of S. aurocapillus, but differ in their somewhat rounder shape, the brilliant polish of their ground, and the greater distinctness of the markings. They varied from .75 to .80 of an inch in length, and from .60 to .62 in breadth.
Geothlypis (I, 295). For a new synopsis of all the species of this genus, see Am. Journ. Science and Arts, Vol. X, December, 1872.
Geothlypis trichas (I, 297). Dr. Cooper found this species wintering in large numbers near San Buenaventura. They frequented the driest as well as the wettest spots.
Geothlypis macgillivrayi (I, 303). We now consider this form a geographical race of S. philadelphia. (See Am. Journ. Science and Arts, Vol. X, December, 1872.)
Myiodioctes pusillus, var. pileolatus (I, 319). See Am. Nat. VII, October, 1873, p. 608.
Setophaga picta (I, 322). This species, not included in the preceding pages among North American Birds, was noticed on only two occasions by Captain Charles Bendire in the vicinity of Tucson, Arizona. This was on the 4th of April, and again on the 12th of September, 1872. He thinks that they unquestionably breed in the mountains to the northward of Tucson. When seen in September they appeared to be moving southward, on their way to their winter quarters. He saw none throughout the summer. (See Am. Nat. VII.) By letter from Mr. Henshaw, we learn that he has obtained this species at Apache, Arizona.
Vireosylvia olivacea (I, 369). Obtained at Ogden, Utah, in September, 1871, by Mr. Allen.
Lanivireo solitarius (I, 373). Dr. Cooper found, April 30, 1870, a male of this species in full plumage and singing delightfully on a ridge above Emigrant Gap on the west slope of the Sierra, about 5,500 feet altitude, and where the snow was still lying in deep drifts. He is confident that he saw the same species at Copperopolis in February, 1864. He thinks there is no doubt that to some extent they winter in the State.
Lanivireo solitarius, var. plumbeus (I, 378). El Paso County, Colorado; Aiken.
Vireo pusillus (I, 391). Dr. Cooper found this species near San Buenaventura as early as March 26, 1872, where it was quite common. On the 22d of April he found a nest pendent between the forks of a dead willow branch. This was five feet from the ground, built on the edge of a dense marshy thicket, of flat strips and fibres of bark, and lined with fine grass, hair, and feathers. There were a few feathers of the Barn Owl, also, on the outside. The nest measured three inches each way. The eggs were laid about the 28th, were four in number, white, with a few small black specks mostly near the larger ends, and measured .69 of an inch in length by .51 in breadth.
