ADDITIONAL DATA FOR YELLOW, WHITE, VERMILION, AND MINIATURE.
Considerable new work has been done by various students upon the linkage of the older mutant characters, namely, yellow, white, vermilion, and miniature. We have summarized these new data, and they give values very close to those already published. We have included in the white miniature data those published by P. W. Whiting (Whiting 1913).
