FIGURE 1. Eurhopalothrix mandibles, showing simple versus double tooth row. A. Dorsal face of mandible, E. oscillum. Teeth are numbered from 1 at the base to 11 at the apex. B. Dorsal face of mandible, E. floridana, with 10 teeth in outer row. C. Interior face of mandible, E. floridana. Lines point to inner tooth row. For species with an inner tooth row, note common condition in which outer tooth 1 is somewhat broadened, tooth 2 is long and sharp like inner teeth, teeth 3–6 are shorter and not as sharp, teeth 7–10 are slightly developed as an apical fork, with outer teeth long and inner teeth short.
