The orifice opens into the branchial cavity behind a conical lobe, which stands above the third foot in place of a branchia which is wanting in Ocypoda.
The two apertures lie just above the edge of the fold of membrane which runs from the inner root of the larger or outer branchia, across the branchial cavity and beneath the rectum, to the other side.
Tadpoles (after they have cast their branchia or gills), newts, and rock fish can be used to the extent of six to the gallon.
There are five branchia [l] arches, made up pharyngo -, epi - and cerato-branchials, and the ventral elements fuse in the middle line to form a common plate of cartilage.
