LAMELLIROSTRAL SWIMMERS — ANSERES. 
following particulars : The maxilla is less expanded terminally, the edges being nearly parallel ; 
but on each side, near the end, is a membraneous, somewhat angular lobe, the end of the mandible 
being nearly truncated, and the nail much smaller and narrower than in Spatula ; the nostrils are 
much smaller, and near the base of the bill ; the tertials and rectrices are broad and rounded, 
instead of acute. 
The two American species of Spatula differ more particularly as follows : — 
1. S. clypeata. Male: Head and neck dark metallic green ; jugulum white ; abdomen and 
sides chestnut, unspotted ; back and inner scapulars dusky ; outer scapulars white. 
j Female : Back and scapulars nearly uniform dusky ; bill brown, the mandible dull 
orange. 
2. S. platalea. 1 Male: Head and neck buff, streaked with black ; jugulum, back, and scap- 
ulars (outer as well as inner) deep cinnamon-buff, thickly marked with roundish spots of 
black ; abdomen and sides chestnut, speckled with black. Female : Back and scapulars 
dusky, the feathers broadly bordered and otherwise variegated with buff ; bill wholly 
black. 
The female and young male of S. platalea may also be readily distinguished from those of S. cly- 
peata by the much longer, more cuneate tail, the rectrices being almost, if not quite, as acuminate 
as in the species of Poecilonetta ; thus, while the middle rectrices in a female of S. clypeata measure 
about 3.75 inches, those of an example of S. platalea measure 4.25, or half an inch longer.

Hab. The whole of the Northern Hemisphere ; Australia. Breeding from Texas to Alaska ; 
wintering as far south as Guatemala, Cuba, and Jamaica. 
Sp. Char. Adult male, in winter: Head and neck dark metallic bluish green, much duller than 
in Anas loschas ; breast and outer scapulars white, the former sometimes spotted with dusky ; entire 
abdomen and sides uniform chestnut ; crissum dark metallic bluish green, bounded anteriorly by 
a band of finely undulated grayish white. Back and inner scapulars dusky, the feathers sometimes 
bordered with white ; longer, lanceolate scapulars marked with a mesial lanceolate stripe of white ; 
wing-coverts light grayish blue, the last row tipped with white, forming a narrow band across 
the wing; speculum bright metallic- green, very narrowly tipped with white; tertials dusky 
black, with faint green reflections, and marked toward the end with an indistinct mesial stripe of 
grayish white ; primaries and their coverts dull slate-gray ; rump and upper tail-coverts black, the 
former with faint, the latter with bright, green reflections ; rectrices chiefly grayish white, the middle
