 Perkins, Henshaw and others to observe this rare bird again, we may well suppose that this species is either extinct, or will very soon vanish if any are left.

In former times the Mamo was probably more or less common. Its golden yellow feathers were of great value, and, though the majority of the famous war-cloaks are composed of the feathers of Moho nobilis, a few such cloaks are known to consist of Mamo feathers. It is supposed that it took generations to complete such a cape.

I only know of specimens of this bird in Vienna, Leyden, Paris, Honolulu, Cambridge and Tring.

The two examples in the Vienna Museum were obtained by Fichtel at the sale of the Leverian collection. One is perfect, the other has the upper portion of the bill wanting.
