There seems to be no reason for not referring all the above forms to one species, the ilifferences 

 being merely in the relative amount of black an<l yellow. The greater predominance of the 

 former color we .shoulil expect in specimens from tlie West Indies, where in this family the 

 melanistic tendency is so marked.
