CHAP. 36. (20.)—CLASSIFICATION OF FISHES, ACCORDING TO THE SHAPE OF THE BODY.
Some sea-fish are flat, such, for instance, as the rhombus,[2448] the sole,[2449] and the sea-sparrow;[2450] which last only differs from the rhombus in the lateral position of the body. The rhombus lies with the right side upwards,[2451] while in the sea-sparrow the left side is uppermost. Some sea-fish, again, are long, as the muræna and the conger.
