Breaking through of the shaft stripe pattern at the tip of the neck- and saddle-hackle feathers. Poorly defined and interrupted lacing. Very irregular lacing. Much yellow in the sickles and by-sickles. Completely white feathers on body and thighs. White in wing-flights and tail steering-feathers. Strongly deviating color from the white lace.
