The serpent

genus is similar and in almost all respects furnished
similarly to the saurians among land animals, if one could only
imagine these saurians to be increased in length and to be devoid of
legs. That is to say, the serpent is coated with tessellated scutes,
and resembles the saurian in its back and belly; only, by the way,
it has no testicles, but, like fishes, has two ducts converging into
one, and an ovary long and bifurcate. The rest of its internal
organs are identical with those of the saurians, except that, owing to
the narrowness and length of the animal, the viscera are
correspondingly narrow and elongated, so that they are apt to escape
recognition from the similarities in shape.
