The adult male has the black frontal band fully as broad, and the crest as deep 
golden yellow, as the specimens from the left bank (Humaytha) obtained by 
Mr. Hoffmanns on his first journey in 1906. Those from Paraiso with narrower 
black frontlet and more lemon-yellow crest, though in full. breeding plumage, are 
apparently not quite adult. This is enhanced by the fact that the young male, still 
in the green juvenile plumage, has the crest of the same pale yellow hue. 
C. regina is a perfectly distinct form, though it may prove to be merely a 
geographical representative of the C. pareola group. Mr. De Witt Miller, in his 
excellent monograph of the genus Chiroxiphia,* has suggested that C. regina might 
be closely allied to C. napensis Miller, from Eastern Ecuador. On comparison of 
the two species, I find this surmise to be quite correct. C. regina differs from 
C. p. pareola and C. p. atlantica, but agrees with C. napensis in its rather short 
crest, dark azure-blue mantle, and dark reddish (instead of yellow) legs and feet. 
Unfortunately I have not seen the female of C. napensis. That of C. regina differs 
at a glance from those of C. p. pareola and C. p. atlantica by having the upper parts 
of a much brighter olive-green, and the lower ones, including the under tail-coverts, 
nearly uniform oil-green. The range of C. regina extends over the area comprised 
between the Rio Solimoéns in the north, the Javarri to the west, and the Rio 
Madeira to the east. No other species of Chiroxiphia is known to occur within 
this district.

In addition, I have examined Natterer’s series in the Vienna Museum, con- 
sisting of three adult males from Borba, a couple from Engenho do Gama, Rio 
Guaporé, and a female from Sao Vicente. The specimens from the Rio Madeira 
agree with a large suite from Pardé and Maranhio (Miritiba), in the Munich Museum,
