526 LAMELLIROSTRAL SWIMMERS — ANSERES. 



following particulars : The maxilla is Ifs.s expaiuled tenniiially, the edges being nearly parallel ; 

 but on each side, near the end, i?; a nienibrauoous, soniewliat angular lobe, tiie end of the mandible 

 being nearly truncated, and tiie nail muih ."mailer 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. Mah-: Head and neck dark metallic green ; jugulum white ; abdomen and 



sides chestnut, unspotted ; back and inner scai»ulars dusky ; outer scapulars white. 

 Female: Back and scapulars nearly uniform dusky; bill brown, the mandible dull 

 oiiin;,'e. 



2. S. platalea.* Male: Head and neck buff, streaked witli black ; jugulum, back, and scap- 



ulars (outer 08 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 \ariegated with bulf ; bill wholly 

 black. 



The female and young male of .S'. plntaJea may also be readily distinguished from those of S. cly- 

 peata by the much longer, more cuneatc tail, the rectrices being almost, if not (juite, as acuminate 

 as in the species of PcceUonetta ; thus, while the middle rectrices in a female of S. clypeata measure 

 alxiut 3.75 inches, those of an example of .S. platalea measure 4.25, or half an inch longer.
