and then the female walked off to her nest; and very soon 
after the male went out to sea. In about an hour he came 
. hack to the lake; and his mate then joined him; but I never 
saw her leave the nest until she heard him cooing on the lake. 
They remained a short time on the lake playing about and 
cooing, and then again went out to sea, and did not return 
until the next day. When the old one began to sit the male 
came in every day and took her out to sea, and again accom¬ 
panied her back to the lake; but I never saw him approach 
the nest. I left Michalaski before the eggs were hatched. 
Their principal food here is mussels and other small shell¬ 
fish, for which they dive in from three to six fathoms of 
water. One day I counted from the fort 206 of them feeding 
along a tide-line in the bay; out of the whole number four 
only were females. Their note very much resembles the 
cooing of the Wood-Pigeon often repeated. 
In the general colour of the plumage the male resembles 
the common Eider [Somateria mollissima), except about the 
head, v/here the wdiite of the cheeks shades gradually into 
the green which separates it from the black of the upper 
part of the head. The white line running backwards from 
the eye is wanting; but that separating the green feathers 
on the nape is present. It has a V-shaped black mark under 
the throat, similar to that of Somateria spectahilis ] but the 
fork extends further backwards. The bill is orange at the / 
base, and shading into gamboge-yellow^ at the margin, wdiich 
is of a yellowish horn-colour. The legs are dirty yellow, 
with a shade of orange, the webs dusky. The female very 
much resembles the female of the King Duck; but the spots 
and blotches about the back and scapulars are larger; the 
bill is dark greenish olive, horn-coloured nail; legs and 
toes dusky dirty-looking yellow, with dusky wxbs; iris brown 
in both. 
In form it dilfers much from the common Eider. The 
head is larger and more clumsy, and has the the supra-orbital 
glands more developed, and forming a prominent swelling 
over the eyes. The bill is under and more elevated at the 
base; and the frontal processes end in very sharp points in-
