 The case here discussed is one of the reduction of the intensity 

 of color from crimson through orange to yellow, due, the author 

 concluded, to a change in habitat and to insularity, the insularity 

 doubtless resulting in inbreeding and consequent " deficiency in 

 capacity " to produce the more intense color.
