Genetic Interaction in a Hybrid Pheasant.

Summary. (1) A brief description is given of a male hybrid between Chrysolophus amherstias and Lophophorus impeyanus, two markedly different genera of the Phasianinas. (2) The chief point of interest is the almost complete disappearance of the striking colours and patterns of the two parents, the hybrid being almost entirely black with no or very limited iridescence. (3) The crest-shape of the Amherst is dominant, while the facial skin of the hybrid resembles that of the Impeyan parent. (4) The cape of the Amherst, which is wholly unrepresented in the Impeyan, is present in the hybrid but is reduced in length and feather-breadth, and is not developed on the anterior margin of its normal area; it has not been seen to be spread in display. (5) The tail is roughly intermediate in length and shape. (6) The body-build inclines somewhat towards the Amherst parent, though the size is intermediate. The Impeyan habit of digging with the beak is dominant over the Amherst habit of scratching with the feet.
