branchi-

The mouth is provided with organs of mastication, the branchi are attached to the hind jaws, and the animals have but one eye.

Here again a glass is requisite to appreciate the delicacy and beauty of their locomotive organs, their branchi, and so on.

Within the sack, attached to its carino-lateral end, a folded membrane forms the branchi.

The Branchi, in E. plicatus, are well developed and moderately plicated.

Both folds of both branchi are deeply plicated on both sides; hence the superficies of the whole is very great.
