b Four specimens. 



c Of the four males from Jamaica, only one is in the cinnamon-buffy plmnage, but 

 the three females are all in that plimiage. The difference evidently is not constant, 

 and, judging from indications in some of the other forms of the species I am led to 

 doubt whether there is even an average difference between the sexes.
