@ Seventeen specimens. The longest supracaudal 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.
