In this bird the uppermandible had exceeded the average length by about a thirdof an inch, while the lower mandible was nearly three timesthe normal length. The lower mandible made a half turn,so that what should have been its lower surface, was, at thetip, the upper. It would have been interesting to know ifthis bird was able to feed on seeds and fruit, which normallyform a large part of the food of this species, or whetherit was fed by the mate, which was with it when shot. Atthe time it was collected the stomach was empty, while.

The horny sheath of the bill is called rhampothecaand is formed by the outer layers of the malpygiancells. It resembles in structure the other horny parts,such as claws, nails, and spurs. In some birds, assome of the ducks, this covering remains soft exceptnear the tip, which contains tactile organs.
