in the * Victoria Mountains,” but gives no definite- localities. ‘Several nests 
were seen in oak trees, but not closely examined, however, they were so frail, 
twigs alone having been used in their construction. The eggs could be seen by 
looking through them from below. Their flesh was here excellent, notwith- 
standing they were subsisting principally upon the acorns of the deciduous 
oak (Quercus grisea) .” 
From this we must infer either that the eggs are laid at widely different 
dates at different localities or in different years, or that the nesting season 
extends over a period of more than six months ineach year. The latter supposi- 
tion seems the more reasonable in view of the fact that the breeding season of 
the Ground Dove in the Cape Region is known to cover fully half the year. 
The apparent migration of Viosca’s Pigeons witnessed by Mr. Frazar was 
probably exceptional and due to a failure of the usual food supply. 
The eggs taken by Mr. Frazar measure respectively: 1.53 X 1.09 and 1.48 
x 1.04. They are elliptical ovate in shape, with rather rough, granulated 
shells of a dead, chalky white color.

“Mr. Frazar found Carolina Doves abundant on the Sierra de la Laguna in 
early May, when they were apparently migrating, for all had left the moun- 
tain before the end of the month. They were also seen in large numbers on 
August 23 about half way between Miraflores and San José del Cabo, and at 
the latter place they occurred sparingly during September. On December 3 
a single bird was observed on the Sierra de la Laguna just below the lower 
limits of the pine belt, and the species was common at Triunfo during the last 
week of December. None were met with near La Paz, where, however, Mr. 
Belding found them “very abundant” in the winter of 1581-1882. Their 
presence or absence in any given locality at the latter-season is doubtless 
determined chiefly if not wholly by the food supply. 
In the central portions of Lower California, the Mourning Dove, according to 
Mr. Bryant, is common in March, but less so in April ; still further northward 
Mr. Anthony has seen it in spring and autumn “ from the coast to an altitude 
of 8,200 feet on La Grulla, but not very common anywhere” (Bryant) and 
at various seasons near San Fernando where it is nowhere abundant.! The 
only definite proof of its breeding on the Peninsula seems to be that furnished
