Note 92 — SUPPLEMENTARY NOTES.

I regret to state that the egg-shells, and many highly interesting bones, belonging to unknown genera of birds, from Rangatapu or Waingongoro, in my son's first collection, remain undescribed. My notes and observations on the geological position of the ossiferous deposits of the North Island of New Zealand, derived from the sketches and letters of Mr. Walter Mantell, are published in the Geological Journal; those on his collection of fossils from the Middle Island will appear in the same publication in the course of the present year (1850).
