shorter and with terminal portion abruptly attenuated; and with 
the sexes very different in color. 
Bill longer than head, slender, terete, but with base slightly ex- 
panded; nasal operculum overlapping maxillary tomium, but the 
greater part covered by latero-frontal feathers; maxilla with a dis- 
tinct lateral groove extending about halfway (more or less) from 
nostril to tip. Wing about three times as long as exposed culmen, 
the tenth (outermost) primary, in adult male, slightly shorter than 
ninth, its incurved terminal portion abruptly attenuated, in adult 
female and young male equal, or nearly equal, to ninth, and not 
attenuated. Tail nearly three-fifths as long as wing, in adult male 
deeply emarginate and with rectrices very broad, in adult female 
rounded, with rectrices much narrower. Tarsal feathering short, 
the inner side of tarsus wholly exposed. 
Coloration.—Adult male metallic green (brighter below), the fore- 
head and crown bright violet-blue, the rectrices deep chesnut broadly 
margined with metallic bronze; adult female green above (including 
forehead and crown), under parts grayish white (spotted with green

cuneate spot of dull whitish and a median fusiform area of chestnut 
on proximal portion.
