 a great number of specimens which show that these variations can not be 

 specific. In part they say: 



"We find that we must either multiply the number of small blue 

 woods Ceyces from the Philippines indefinitely or reduce the above-men-

 the blue in the specimens first mentioned. 



"Our series shows that these extraordinary differences of color are
