tioii was apparently satisfactory, it was not placed beyoii<l doubt by 

 securing the parent. The eggs averaged .08 x .53. Neitlier in size, 

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

 fresh eggs of E. minimus that 1 have ever seen. 



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

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



Since the above was written, my friend Mr. Wm. A. Jeffries has ])ro- 

 cured for me, through the courtesy of JNIr. 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 .5o. 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 difficilis; 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 si^ecies 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 l>rown, and the egg 

 is undistinguishable from several eggs in my collection of U. diffieilis. 

 It is very different from the eggs idcn+ified by Mr. Boardman, 



Mr. Osborne writes me that none of this set differ more than -j-§^ in 

 theu' measurements, and that in their color the oi' '.y jwints in which any 

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

 and the larger size of the blotches.
