QUERQUEDULA EATONI. 5 



A rather small cluck, the sexes of which differ but little (chiefly iu the vividness of 

 the alar speculum). Head and neck minutely speckled with blackish-brown and light- 

 brown or brownish- white— the top of the head darkest, the sides of the head, the neck, 

 and especially throat lightest. Upper parts brownish-black ; all the feathers broadly 

 skirted with rusty-brown and pale-gray. Under parts dull whitish, mottled through- 

 out with brown, more uniform and of a richer shade on the breast, in l^S-ger pattern on. 

 the sides and crissum. Axillars white, with dark-brown cross-bars ; lining of wings 

 dark-brown, with paler or white edgings of the feathers. Wing-coverts plain grayish- 

 brown, or, in the $ , with narrow rusty-brown edgings ; the greater row of coverta 

 tipped with orange-brown, paler or whitish in the 2 . Speculum iridescent green, with 

 purplish and violet reflections, immediately bordered with bl.ick, this in turn margined 

 with white on the ends of the secondary quills. In the $ , the green speculum is dull, 

 and tinged with brown. Primaries fuscous-brown ; tail-feathers the same, with pale 

 edges, and irregular oblique rusty-brown markings, like broken V-shaped bars. The 

 tail-feathers are all lanceolate-acuminate, and the tail as a whole is acute. — C.
