Geothlypis (F, '_".»•")). Kd- a new synoj)sis of ail tlie species of thi.s j^enus, sco 

 Am. Joiirn. Science and Arts, \ol. X, l)i'cenil)er, 11^72. 



Geothlypis trichas (I, L"J7). Dr. Cooper fmnid tiiis specii's wintei'inj^ in 

 large nuniL)er.s near .San Buenaventura. Tliey fie(piented tiie driest as well as 

 the wettest sjjots. 



Oeothlypis macgillivrayi (1, :?0;>). We now consider tiiis form a gco- 

 grapliical race of .V. j/fii/tnlc/jihid. (See Am. Journ. Science and Arts, Vol. X, Do- 

 eonibur, 1872.) 



MjriodiOCtes pusillus, var. pileolatUS (I, 31!)). See Am. Nat. VI 1, Octo- 

 ber, it<7;i, p. GUf>. 



Setophaga piCta (I, 322). This species, not included in tlic pi-ecoding 

 paues amony: North .\merican IJirds, waij noticed on only two occasions by Cajitain 

 Charles liendire in the vicinity of Tucson, Arizona. This was on the -ith of 

 April, and again on the 12th of September, 1872. He thinks that they \u\- 

 (piestionably breed in the nioimtains to the northward of Tucson. When seen 

 in September they a[)peared to be moving .southward, on their way to their winter 

 (piarters. He saw none throughout the sunnner. (See Am. Nat. VI 1.) l>y letter 

 from -Mr. Henshaw, we learn that he has obtained this s]iccies at Apache, Arizona. 



Vireosylvia olivacea (I, 3(ilt). Obtained at Ogden, Utah, in Se2)tembcr, 

 1871, by Mr. Allen. 



Lanivireo SOlitariUS (I, 373). Dr. Cooper found, A])ril 30, 1870, a male 

 of this species in full plumage and singing delightfully on a ridge aliove JMiiigrant 

 (iap on the west slope of the Sierra, about r),.500 feet altitude, and where the snow 

 \va.s still lying in deej) drifts. Ho is contident that he saw the same species at 

 Copperopolis in February, 1804. He thinks there is no doubt that to some extent 

 they winter in the State. 



Lanivireo SOlitariUS, var. plumbeus (1, 378). El Paso County, Colorado; 



AlKKX. 



Vireo pusillus (T, 391). Dr. Cooper found this species near San Buenaven- 

 tura as early as March 20, 1872, where it was quite common. On the 22d of 

 AjM-il ho found a nest pendent between the forks of a dead willow branch. This 

 was tive feet from the groimd, 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 meas- 

 ured three inches each way. The eggs wei'o laid about the 28th, were four in 

 number, white, with a few small black specks mostly near the larger ends, and 

 measin-ed .0!) of an inch in length by ..")1 in breadth. 



Phaenopepla nitens (I, 10")). Captain Bcndire writes me that he found this
