« Seventeen specimens. The longest supracaiidal plume in a series of one hundred 

 adult males from Costa Rica examined at one time measured 774.5 mm., while the 

 longest in another series of seventy-seven adult males measured 787 mm. In none 

 of the entire lot of nearly two hundred adult males examined were these plumes 

 nearly as wide as in the average of Guatemalan examples, usually not more than 

 about half as wide.
