apparatus. The cerebrum and the cerebellum have been included to indicate the 
relative size of the olfactory lobes.

PLATE 1 
EXPLANATION OF FIGURES 
(All figures X 1) 
1 Dorsai view of olfactory lobes and nerves in Struthio camelus, (ostrich). Pos- 
terior ends of nasal chambers shown semi-diagrammatically. 
2 Dromaeus novae-hollandiae, (emeu). Dorsal view showing olfactory lobes 
and a portion of the nasal chambers. A posterior portion of the roof of the left 
nasal chamber has been dissected away to show the contour of part of the posterior 
turbinal. The right posterior turbinal and a posterior portion of the right middle 
turbinal are also exposed. Contour lines for the eyes and bill have been sketched 
at the sides of the drawing for orientation. 
3 Dromaeus. Lateral view of specimen shown in fig. 2, but without the nasal 
chambers. 
4 Turtur risorius, (ring dove). Dorsal view to show olfactory lobes, olfactory 
nerves, and sections of the ophthalmic branch of the trigeminus nerve. 
5 Fulmarus glacialis, (fulmar). Dorsal view of portion of dissected head with 
the brain case material which separates the eyes from the brain removed. The 
right nasal chamber and a posterior portion of the left nasal chamber are exposed. 
The posterior turbinal of the right side has been opened at d to show the turns or 
rolls of its structure. The middle and anterior turbinals have been mutilated 
slightly in the dissection. 
6 Fulmarus. Lateral view of right olfactory lobe. A small posterior bit of 
the right nasal chamber is represented semi-diagrammatically in contact with the 
right olfaetory lobe. 
7 Pavoncella pugnax, (ruff). Dorsal view. Sections of the ophthalmic 
branches of the trigeminus nerve are figured pulled apart very slightly to avoid 
confusing their outlines with those of the olfactory nerves. 
8 Pseudotantalus leucocephalus, (white-headed ibis). Dorsal view to show 
olfactory lobes and nerves.
