Smithsonian Xo. 17593. San Franeisco, Ca^. Samuel Ilubbard. .70 

 X .52 ; .05 X .50 ; .08 x .50 ; average .08 x .51. The ground-color of these 

 three examples is a creamy white, almost a dead white, and they are 

 chiefly spotted around the larger end with markings of a brownish red 

 and a few faint spots of lavender. The color of the markings of this set 

 has no resendjlance whatever to those of 13440 {U. Jfai'ircntri.s) when 

 carefully compared. 



T. M.B. No. 605. Monterey, Cal. Dr. Canfleld. .76 x .59; .74 x .59. 

 Spotted with light-brown markings, on a creamy ground, the markings 

 being exclusively around the larger end. 



T. M. B. No. 2900. Santa Cruz, Cal. William A.' Cooper. The female 

 parent was shot by Mr. Cooper, and was sent to Washington for identi- 

 fication. The nest was in a hollow in a bank, covered with roots and 

 bushes. Incubation just begun, May 4, 1878. .09 x .50; .69 x .51; .70 

 X .52 ; .69 x .52. These four eggs, as indeed nearly all of the eggs of this 

 species that I have ever seen, are conspicuously marked with vivid light 

 reddish-broA^Ti spots. In three of this set they are chiefly on the larger 

 end ; in one the markings are distributed over the whole egg. Ground- 

 color a creamy white. 



T. M. B. No. 2959. Nieasio, Marin County, Cal. C. A. Allen. The 

 female parent was shot by Mr. xVllen and identified by Mr. Bidgway. 

 .70 X .53 ; .70 x .54 ; .05 x .54 ; .70 x .55. Marked with large bright red- 

 brown spots, chiefly about the larger end. This nest was also built in 

 a cavity. 



T. M. B. No. 2728. Santa Cruz, Cal. Geo. H. Keady. Sent me as 

 JE. jiusillus, but evidently a wrong identification. The nest Avas on a 

 horizontal sycamore limb, ten feet from the grouiul. .08 x .55 ; .70 x .57 ; 

 .70 X .57 ; .08 x .58. 



T. M. B. No. 2800. Haywood, Cal. Dr. J. G. Cooper. May 25, 1877. 

 .70 X .55 ; .70 X .55 ; .60 x .55 ; .08 x .52. The last-mentioned cg<^ is of a 

 very nearly unspotted white. 



T. M. B. No. 3053. Santa Cruz, Cal. Geo. II. Beady. April 22, 1877. 

 Nest on the lower limb, at the extremity, of a sycamore, ten feet above 

 the ground. .00 x .52 ; .05 x .53 ; .07 x .53. These eggs are, with hardly 

 a doubt, those of -E7. <7/^c?7/.§, though mistaken by Mr. E. for 2)usillus. 

 Their ground-color is pure creamy white. The spots are few, small, and 

 of a more than usually faint brown, disposed in rings around the larger 

 end, the residue of the eg'^ being unspotted. 



In 24 examples, the greatest length is .76, least .65, average .69 ; great- 

 est breadth .59, least .50, average .54.
