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 constraction. 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 in each 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 tlie 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 Lnguna 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 Jos^ 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 Decoriber. None were met with near La Paz, where, however, Mr. 

 Belding found them "very abundant" in the winter of lS81-]882. Their 

 presence or absence in any given locality at the latter season is doubtless 

 determined chiefly if not wholly by the fond 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 GruUa, 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
