ring. They resemble the eggs of S. anrocapillus, but differ in their somewhat 

 rounder shape, the brilHant 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. Jouru. 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 geo- 

 graphical race of /S'. Philadelphia. (See Am. Journ. Science and Arts, Vol. X, De- 

 cember, 1872.) 



Myiodioctes pusillus, var. pileolatus (I, 319). See Am. Nat. VII, Octo- 

 ber, 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 un- 

 questionably 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 

 quartei's. He saw none throughout tlie 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 lie 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 (1, 391). Dr. Cooper found this species near San Buenaven- 

 tura 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 gi-ass, hair, and feathers. 

 There were a few feathers of the Barn Owl, also, on the outside. The nest meas- 

 ured 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 

 measiared .69 of an inch in length by .51 in breadth. 



Fhaenopepla nitens (1, 405). Captain Bendire writes me that he found this 

 species common in the vicinity of Tucson, Arizona, during the summer, a few only re-
