This series shows the interesting and curious development with age of the horny plates on the upper mandible. The youngest specimens have merely a raised lump, while the oldest has no less than seven plates, and the bill is longer and stronger than in the younger birds. The young male (spec, c) has a black spot on the extremity of each of the tail-feathers, which is absent in the rest of the series, and Mr. Woodford assures me it is the only specimen in which he ever observed this peculiarity. 22.
