8. It has two teeth like the carabus, above these the long horns, much shorter and smoother than in the carabus; four others of the same form as these, but still shorter and smoother; and above these are placed its eyes, which are small and short, and not large like those of the carabus. The part above the eyes is acute and rough, as it were a forehead, and larger than in the carabus: on the whole, the head is sharper and the thorax much wider than in the carabus, and its whole body is more fleshy and soft: of its right feet, four are divided at the extremity, and four not divided. 9. The part called the neck is externally divided into five portions, the sixth and last division is wide and has five plates; in the inside are four rough plates, upon which the females deposit their ova. On the outside of each of these which have been mentioned, there is a short and straight spine, and the whole body, with the part called the thorax, is smooth, and not rough as in the carabus. On the outside of the large feet there are great spines. The female does not in any way differ from the male, for whether the male or female have larger claws, they are never both of them equal. 10. All these animals take in sea-water through their mouths; the carcini also exhale a small portion of that which they have taken in, and the carabi do this through the branchiform appendages, for the carabi have many branchiform appendages. All these animals have two teeth: the carabi have two front teeth, and then a fleshy mouth instead of a tongue, from this an œsophagus continued on to the stomach. And the carabi have a small œsophagus before the stomach, and from this a straight intestine is continued. In the caraboid animals and the carides, this is continued to the tail in a straight passage, by which they eject their excrements, and deposit their ova. In the carcini this is in the middle of the folded part, for the place wherein they deposit their ova is external in these also. 11. All the females also, besides the intestines, have a place for their ova, and the part called mytis[119] or mecon, which is greater or less, and the peculiar differences may be learned by studying the individual cases. The carabi, as I have observed, have two large and hollow teeth, in which there is a juice resembling the mytis, and, between the teeth, a piece of flesh resembling a tongue; from the mouth a short œsophagus extends to a membranous stomach; in the part of this nearest the mouth are three teeth, two opposite and one below.
