On some points in the Anatomy of _Nautilus pompilius_. By T. H. HUXLEY,
F.R.S., Professor of Natural History, Government School of Mines.

[Read June 3rd, 1858.]

Some time ago my friend Dr. Sinclair, of New Zealand, had the kindness
to offer me two specimens of the Pearly Nautilus which had been brought
to him from New Caledonia, preserved in Goadby's solution. I gladly
accepted the present, and looked forward to the dissection of the rare
animal with no little pleasure; but on proceeding to examine one of the
specimens, I found its anatomical value greatly diminished by the manner
in which a deposit from the solution had glued together some of the
internal viscera. Other parts of the Nautilus, however, were in a very
good state of preservation; and I have noted down such novel and
interesting peculiarities as they presented, in the hope that an account
of them will be acceptable to the Linnean Society.

Of the six apertures which, besides the genital and anal outlets, open
into the branchial cavity of _Nautilus pompilius_, one on each side lies
immediately above and in front of that fold of the inner wall of the
mantle which forms the lower root of the smaller and inner gill, and
encloses the branchial vein of that gill. The aperture is elongated and
narrow, with rather prominent lips. It measures about 1/8th of an inch.

The other two apertures are larger, and lie at a distance of 7/1
