sexual difference in the color of the shield is not borne out b>' in>- 
observations, nor by ni)’ specimens, in which the bills of mature females 
are cpiite as richly colored as those of males. In one adult male. No. 
1801, Feb. I, 1913, the shields are flaking' off. 
The color of the reticulated iris is raw umber. The ]>upil is S(jiunr 
when contracted ; when dilated it takes a ])ol\'^'onal sha])e, like an “ iris” 
diaphragm of a ])ht)tographic lens. In life, the prominent nictitating 
membrane is frequentl\' drawn over the eye. 
The auricular- patches of mature birds are cadmium }-ellow ; at the 
front of the neck, where the branches are confluent, the color becomes 
orange. The ])o.sterior edge of the patch, where it joins the blui.sh tone 
of the hind neck, is distinctly green, the blending of the yellow and 
blue ])roducing a solid color on the individual feathers. The concealed 
portions of the _\'ellow feathers of the ear-patches are white ; tho.se of the 
feathers on back and brea.st, gra>dsh. The feather-shafts are character- 
istically flattened and curved, with a width as great as 2 mm. Becau.se 
of their external convexity they exert a s])ring-force again.st the body 
and function as shingles over the downy aftershafts. The feathers are 
placed equidistant from one another, forming regular, transverse and 
diagonal rows over the whole skin. One, or more often two, fllo]flume.s 
s])ring from about the ba.se of each feather. The aftershafts are single, 
but in the form of complex tufts. They are attached at the ba.se of the 
inner surface of the flattened quills, by wdiich they are matted snugly 
against the bod}^ 
The large eggs of the king penguin are subpyriform, and of a pale 
olive-green color. An egg taken from the oviduct of a dead bird is pure 
white. vSoon after being dejxxsited, however, the eggs become .so 
])lastered with mud that the original color of the .shell is indi.stinguish- 
able. Measurements in millimeters of six sjiecimens are : 108 x 77, 
98 X 74, 96 X 75, 108 X 76, loi X 76, 107 X 75.
