 occurring- in the southern hemisphere, this genus leads directly 

 to PcBcUonetta, which in turn is intermediate between Nettion and 

 Dajila. 



The two species of Nettion occurrinj^ in the northern hemi- 

 sphere are much alike, the males bein<»: very handsome in 

 plumage. They may be distinguished as follows: 



ComiON Chaeactebs. Adult males: Head aud upper half of the neck chostnufc-nifons, 

 marked with a large patch of metallic green on each side of the head, behind the eye; 

 chin and upper part of throat dull black; nuchal tuft blue-black; lower part of the neck, 

 upper part of the back, scapulars, and lateral parts of the body beneath, undulated with 

 bla'k and white; outer scapulars marked with black and white; speculum bright metallic 

 green, the lower feathers black, tipped with white; crissum black centrally, creamy buff 

 laterally. Adult fetnales: Wing, only, as in tlie males; elsewhere varied with dusky and 

 brownish white, the former prevailing above, the latter beneath; the abdomen nearly or 

 quite immaculate. 



1. A carolinensis. A broad white bar across side of breast, before the wing; inner 

 webs of outer scapulars vermiculated with dusky and brownish white, the outer 

 webs marked witii a longitudinal lanceolate spot of black, bordered internally with 

 a white line. 



[2. A. crecca. No white bar on pide of breast; inner web of outer scapulars wholly, 

 and outer web partly, white, the exposed surface of outer webs almost entirely 

 black: undulations of sides, etc.. much coarser than in A. carolinensis. Hab.
