Much black in wing tip. Faint broken band on P5 and complete sub-terminal band on P10. Innner web of P10 with much black (broad medial band). Thayeri pattern on P9 combined with broad sub-terminal band. Medial band on P9 continues on inner web on right wing, and still it completely covers outer web at the mirror.

Bird probably best matches option Plate 3-b.
