This envelope, with its minute divisions, is beheld in the drawing at a, and encases nearly the entire body of the animal. In some species the shell is adorned with diamond-shaped figures, in others its surface is composed of, hexagons like that of a honey-comb; and a diversity of other angular figures embellish the cases in the different remaining varieties of the Lynceus.

These members also subserve another purpose, causing the animal, as it advances through the water, to proceed with a revolving motion; in which action it is also aided by the appendage I, which, striking against the water like a fin, renders the rotatory motion of the Lynceus m...
