 atricapilla Vieillot, = Cerlhia spiza Linnseus. )

 slightly decurved terminally, the maxillarj^ tomium more or less dis- 

 tinctly notched sub terminally; adult males glossy green, with pileum 

 and sides of head black; or if violet-blue, the pileum also blue. 



Bill about as long as head, or a little longer, narrow, gradually taper- 

 ing and slightly decurved terminally; culmen straight or nearly so for 

 about basal half, then gently decurved to the tip; gonys straight or 

 very slightly concave toward tip; maxillary tomium with a slight sub- 

 terminal notch. Nostril exposed, longitudinal, narrow, overhung by 

 broad membrane. Rictal bristles minute, very weak. "Wing moder- 

 ate, rather pointed (eighth, seventh, and sixth primaries longest, ninth 

 much longer than fifth), the tip about equal to length of tarsus. Tail 

 much shorter than wing (decidedly shorter than distance from bend of 

 wing to tip of secondaries), emarginated. Tarsus rather short (about 

 one-fourth as long as wing or a little less, less than length of commis- 

 sure), its scutella rather distinct; middle toe with claw shorter than 

 tarsus.

 bluish green, with pileum and sides of head black, or else violet- blue
