Yoitn^.— Similar in general coloration to adults, but blue of head 

 and neck much duller, more or less suffused or intermixed with green, 

 the forehead usually with a broken band, or a patch on each side, of 

 light red ; under taU-coverts with the red paler and duller, as well as 

 much more restricted (the green correspondingly more extended) ; 

 wing-coverts greener, more nearly concolor with back. 



Adult maZe.— Length (skins), 220-285 (246); wing, 167-195.5 

 (182.3); tail, 60.5-82.5 (73.9); culmen, 22-26.5 (24.4); tarsus, 18-21 

 (19.4); outer anterior toe, 22-25.5 (23.8).« 



Adult female.— Length (skins), 217-272 (241); wmg, 161.5-195 

 (175.7); tail, 65-80 (72); culmen, 22.5-25 (23.8); tarsus, 17-20.5 

 (18.9); outer anterior toe, 21.5-25 (23.2).^ 



a Forty-one specimens. 

 b Twenty-five specimens 



After careful examination and comparison of about one hundred specimens, from 

 practically all parts of the range of the species, I am unable to detect sufficiently con- 

 stant variations in coloration or measurements to admit of the definition of geographic 

 forms or subspecies. In the first place, it may be stated that the alleged greater 

 amount, or greater frequency, of red on the throat in examples from Panama and Costa 

 Rica is not shown by the series examined. The only tendency toward geographic 

 differences in coloration that I am able to find is in the brighter, or more intense, 

 coloration shown by many specimens from Venezuela and Colombia (especially the 

 former) as compared with those from Panama and Costa Rica.
