Californie). 
So far as known, this Vireo is strictly confined to the Cape Region, where it 
is found at all seasons of the year, although most numerously, perhaps, in 
summer. Its breeding range extends from the coast at San José del Cabo, 
where it occurs almost exclusively in cultivated grounds about houses, to Mira- 
flores and San José del Rancho, at both of which places it is common. Only 
a few were seen by Mr. Frazar at Triunfo, and none on the Sierra de la Laguna, 
while but one bird was taken (on April 4) at La Paz, which appears to be be- 
yond the northern limits of its usual range. At San José del Rancho two 
specimens were killed in December, one on the 20th, the other on the 23d. 
No form of V. solitarius is recorded by Mr. Bryant from anywhere north of 
La Paz in Lower California, but Mr. Belding reports that Colonel Goss found 
V. s. cassinuw at Tia Juana, on March 20,! and Mr, Anthony states that at San 
Pedro Martir it was ‘‘not uncommon in the pines where it was first seen 
May 13,” and where “it became more common a week or so later.”2 It is a 
common summer resident of portions of California, and may occasionally visit 
the Cape Region of Lower California during migration or in winter. 
A nest of V. s. lucasanus containing four fresh eggs, found by Mr. Frazar at 
San José del Rancho on July 15, was suspended in a fork at the extremity of 
a long, leafless branch of an oak at a height of about fifteen feet. It is com- 
posed chiefly of a gray, hemp-like fiber mixed with grass stems and thin strips 
of bark. There are also a few spiders’ cocoons loosely attached to the bottom 
and sides, and apparently intended as ornaments. The interior is very neatly 
lined with fine, wiry, reddish-brown grass circularly arranged. This nest 
measures externally 3.00 in diameter by 2.50 in depth; internally, 2.00 in 
diameter by 1.50 in depth. The walls are half an inch thick in places. The 
eggs measure respectively : .79 X .56, .79 x .57, .80 X .57, and .80 X 58. 
They are white, with a slight creamy tint, and are spotted, chiefly about the 
larger ends, with reddish brown and black. Both nest and eggs are very like 
those of V. solitarius.
