tlae size and coloration of the bill. In true griseigena the bill is 

 little, if any, over 1.50 inches along the culmeu, or 2.00 along 

 the gape, and the yellow is either entirely restricted to the base, 

 or only extends thence a little on the edge of the under man- 

 dible. In var. liolbolli the above-mentioned measurements of 

 the bill are respectively 1.90 and 2.40, and much or most of the 

 under mandible, with the cutting-edges of the upper, are yellow. 

 In the present specimen, the culnien measures 1.60; the gape, 

 2.15, /and there is little yellow, excepting^at the base of the 

 bill. 



Eggs of the American red-necked grebe, from the Yukon 

 and other interior arctic localities, are rough, white, either 

 inclining to pale-greenish or with buffy discoloration, and of 

 the usual narrowly-elongate shape common in the family. They 

 measure from 2.10 to 2.35 in length by 1.25 to 1.45 in breadth, 

 the longer eggs not always being proportionally ■wide. 



"It is the only specimen seen during my residence upon the 

 islands. It has been observed before by the natives, who, how- 

 ever, affirm that it is uncommon."

An egg before me is noticeably more elongate than that of 

 F. arctica or of F. eirrhata, though not more pointed. The shell 

 is rather rough, and dead-white. We may anticipate that in 

 some instances a few obscure obsolete spots may appear, as 

 they occasionally do in the eggs of F. arctica, and, doubtless, 

 also show the usual discolorations in many cases. The pres- 

 ent specimen measures 2.75 by 1.75.
