As the muscles of the limbs reach their maximum of number and variety in the Chelonia and saltatory Batrachia, they will be specified in those groups ; and the myology of the trunk will be resumed, as it is seen in the Opiudla. In these reptiles, as might be expected from the functions of the spinal column, specialisation of the muscles of the vertebra; and ribs reaches its maximum. The coalescence of the upper or neuromesial and neurolateral parts of the myocommas into longi- tudinal tracts is more complete and distinct than in the fish-like Batrachia, or the CroeodiUa; the primitive distinction or segmentation being pre- served only at the points of attachment. In the neuromesial tract, fig. 143, A, those which may be called ' origins ' are in two series, one from the bases of the neural spines, the other by short tendons from the diajiophyscs: the flesliy fibres from each ori- gin converge and coalesce as they pass forward, and terminate in a long slender tendon: these tendons are attached to the summits of the neural spines.
