“ Fore head, cheeks, and chin, pale ochreous-yel- 
low; region of the eyes, crown of the head and 
nape of the neck, greyish white ; neck, as far as the 
collar, oclireous-yellow, tinged with orange ; collar 
about half an inch in width, glossed with green ; 
breast, mantle, scapulars, and under parts of the 
body, gall-stone yellow tinged with orange, being 
deepest upon the breast ; the feathers on the upper 
parts of the body have their margins paler, and the 
long tertials pass into sienna yellow ; lesser and mid- 
dle wing- covers white ; secondary quills green, gloss- 
ed with purple, and forming a large speculum ; 
greater quills black ; lower part of the back, upper 
tail-covers, and tail, black glossed with green ; bill, 
legs, and feet black.”* Female is said to want the 
black collar. 
We shall next examine the true ducks, or those 
where the lamina; of the hill are farthest developed, 
and shall show first the form of which the common 
wild duck is typical, as carrying forward the great 
facility or domestication in a species which in its 
native haunts exhibits exceeding wariness. We 
do not here find the laminas either much developed 
or exposed, at the same time the whole food is taken 
by searching for it in the mud or among the aquatic 
vegetation, as any one may observe by noticing our 
common breods of ducks while feeding, grain or 
food of any kind when placed even in clean water,
