it were, so as to fully expose the lamellae. Through the forms 

 occurrinp; in the southern hemisphere, this genus leads directly 

 to PtvcUonetta, which in turn is intermediate between Nettlon and 

 Dnfila. 



The two species of XMlon occurring in the northern hemi- 

 sphere are much alike, the males being very handsome in 

 plumage. They may be distinguished as follows: 



Common Ch.vbactebs. Adult males: Head and upper half of the neck chestnut-rufous. 

 marked with a large patch of metallic gieen 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; orissum black centrally, creamy bull' 

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

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

 quite immaculate. 



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

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

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

 a white line. 

 [2. A. cretoa. No white bar on side 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. Uab. 

 Palicarctio Regiou, occasional in eastern North America.]
