their form is a long ovoid; and their dimensions average 
about 2.15 inch in length by 1.50 inch in breadth.

lope, L.) 
Bill shorter than the head, and equal to the inner toe claw; the sides parallel to 
near the end, which is rather obtusely pointed, the nail occupying the tip, and about 
one-third as broad as the bill; bill rather high; the upper lateral angle at the base 
not prominent, nor extending as far back as the lower edge; tail pointed, not half 
the wings. 
The North-American and European species of Mareca have the upper parts 
finely waved transversely with black and gray or reddish-brown; the under parts, 
with the usual exceptions, snowy-white. The top of the head is uniform white or 
cream-color; the neck more or less spotted; the middle and greater coverts are 
white, the latter tipped with black; the speculum is green, encircled by black; the 
tertials are black on the outer web, edged with hoary-white; the entire outer web of 
one of them hoary.

DESCRIPTION. 
Male. — Tail of fourteen feathers; bill blue, the extreme base and tip black; 
head and neck pale-buff, or faint reddish-yellow, each feather banded narrowly with 
blackish, so as to give the appearance of spots; the top of the head from the bill is 
pale unspotted creamy-white; the sides of the head from around the eye to the nape, 
glossy-green, the feathers, however, with hidden spots, as described; chin uniform 
dusky; forepart of breast and sides of body light-brownish or chocolate-red, each 
feather with obsolete grayish edge; rest of under parts pure-white; the crissum 
abruptly black; the back, scapulars, and rump, finely waved transversely anteriorly 
with reddish and gray, posteriorly with purer gray, on a brown ground; a little of 
the same waving also on the sides; the lesser wing coverts are plain gray; the mid- 
dle and greater are conspicuously white, the latter terminated by black, succeeded 
by a speculum, which is grass-green at the base, and then velvet-black; the tertials 
gre black on the outer web, bordered narrowly by black, the outermost one hoary- 
gray, externally edged with black; the tail is hoary-brown; the upper coverts are 
black externally; the axillars are white; iris hazel. 
The blackish chin appears to be found only in very highly plumaged birds. The 
top of the head is sometimes pure-white. 
The female has the head and neck somewhat similar, but spotted to the bill; 
wings as in the male; the black of tertials replaced by brown; the gray of the lesser 
coverts extending slightly over the middle ones; back and scapulars with rather
