tion was apparently satisfactoiy, it was not placed beyond donbt by 

 securing the parent. The eggs averaged .68 x .03. Neither in size, 

 shape, nor in the shade of ground-color, did they at all resemble any 

 fresh eggs of E. minimus that I have ever seen. 



In these ten specimens, the greatest length is .70, the least .07, aver- 

 age .73; the greatest breadth is .58, the least .53, average .55. 



Since the above was written, my friend Mr. Wm. A. Jeffries has pro- 

 cured for me, through the courtesy of Mr. Deane, the measurements of 

 the four eggs procured by the latter in Maine, and described by Mr. 

 Purdie. These measure .70 x .55; .70 x .55; .05 x .52; .70 x .55, and re- 

 duce the average to .72 x .55. The eggs are described by Mr. Jeffries as 

 of pure white ground, with markings in two eggs of line dots; in the 

 others, small irregular blotches, of a light red-brown, not so deep or so 

 bright as in difficUis; mingled with these are a few markings of lilac. 

 The ground-color appears to have lost the rosy tint mentioned by Mr. 

 P. in the first description, in which, too, no mention is made of the lilac- 

 colored spots. 



Through the kindness of Mr. Osborne I have also been enabled to 

 examine one of the eggs contained in the nest of this species found by 

 him in Grand Menan. It measures ,70 x .50, and agrees exactly with 

 the description given by him, except that there is a slight roseate tinge 

 in the white ground. The spots are a light reddish brown, and the egg- 

 is undistinguishable from several eggs in my collection of E. difficUis. 

 It is very different from the eggs identitied by Mr. Boardman. 



Mr. Osborne writes me that none of this set differ more than yf^ in 

 their measurements, and that in their color the only points in which any 

 differ from the one described are the lighter shade of the ground-color 

 and the larger size of the blotches.
