92 Supplement to the History

# ON CARPS

Since many varieties of these fish were recorded in their dedicated *History*, we are now presenting an examination of the internal parts of the marsh carp, as follows:

A. 1. The inner surface of the bony gill arches, which is fringed on both sides. Likewise, the lower surface of the bony arch is fringed on both sides, just as the upper part is villous, being marked by a double row of fine filaments.

C. The socket in which the "carp stone" is held.

4. The exterior portion of the carp stone.

5. The interior portion of the same stone.

AA. An inner tooth of the first row and second size.

BB. A tooth of another row (the middle one), of the first size, and the largest of all.

CC. A tooth also of the second row and third size.

DD. A tooth likewise of the second row, and the smallest of all in size.

EE. A tooth of the third row which, due to its shape, may be called papillary.

FF. The internal part of the jaws facing the belly.

A. The lower bladder positioned toward the tail.

B. The upper bladder ending at the stomach.

C. The external membrane of the bladder.
