The acute membranous lobe which fills the notch between the two opercular spines is likewise scaly, and there are a few scales about the origin of the ridges, but the space between the ridges, the sub-operculum, and the inter-operculum, are naked.

The frontal lobes of the brain are the central offices for higher thought.

The lobe of the ear was slit, the hole being either kept distended by a large plug of rolled-up leaf, apparently of the banana, or hung with thin circular earrings made of the ground down end of a cone-shell (Conus millepunctatus) one and a half inches in diameter, with a central hole and a slit leading to the edge.

The supposition, that in such cases all the lobes of each squama are cells of one and the same anthera, receives but little support either from the origin and arrangement of the lobes themselves, or from the structure of other phaenogamous plants: the only cases of apparent, though doubtful, analogy that I can at present recollect occurring in Aphyteia, and perhaps in some Cucurbitaceae.
