Tlu-ro seems to be no reason for not rcf.Mriiig all the above forms to one species, the dUIen'iues 

 being merely in the relative amount of bhu'k and yellow. The great.'r predominance of the 

 former color we slioidd exi.eet in specimens from the West Indies, where in this fauuly the 

 nielanistic tendency is so marked.
