page 420 note 2 The complete bony boundary of the orbit is rare in recent birds (the Psittacidæ e.g., see Owen's Anat. Verts, vol. ii. p. 51, fig. 30). In Arehæopteryx it seems to have been continuous around the orbit.Google Scholar

page 421 note 1 The antorbital vacuity in most recent birds is confluent with the anterior nasal foramen (e.g. Alca, Aptornis, Dinornis), not distinctly separated as in Archæopteryx. Didus shows a bar between the vacuities, but in Pezaphaps it is wanting. In Apteryx the anterior nostril is most remote from the ortorbital vacuity. (See Owen's Extinct Wingless Birds, pl. i. fig. 1, pl. lxxxiii. fig. 1, pl. lxxv. fig. l, pl. viii.) Odontopteryx (Q. J. G. S. vol. xxix. pl. xvi. fig. 2nGoogle Scholar) shows an extensive tract of bone between the nostril (n) and the antorbital vacuity (73, fig. 8), the corresponding dividing plate between the antorbital and nasal openings in Archæopteryx is narrow when compared with Odontopteryx, the antorbital vacuity being very large in the former.
