The mark (Ji) corresponds in every respect with the basal shaded spot of the simple feather described in the last paragraph (fig. 58), but is more highly developed and more brightly colored. Above and to the right of this spot {b, fig. 59), with its bright shading, there is a long narrow black mark (r), belonging to the same row, and which is arched a little downward so as to face b. This mark is sometimes broken into two portions. It is also narrowly edged on tha lower side ^vith a fulvous tint. To tiie left of and above.
