At tlie l^ase of the tail it descends to tlie lower border, and covers part of the third muscular column. This derives a tendinous origin from the inner trochanterian ridge of the femur, and from a ligament thence extending to the femoro- fibidar articidation : from those attachments the muscle passes l^ackward to the haemal arches and spines related thereto by alternating origins and insertions, and there assumes the myocom- nial character of the lowest or hasmal tract in the tail of the Newt and Fish. By its anterior attachments in the Crocodile, this series of muscles — t\\efemoro-j]ero7ieo-(:occy(iiuii of Cuvier—closely asso- ciates the pelvic limljs with the tail in the natatory actions and evolntions of the amphibious carnivore. The mandiljvdar muscles are strongly dc^•cloped m the Cro- codile in comparison with other Saurians ; 112 although they seem, after a comparison with those of carnivorous mammals, small in pro- portion to the length and massiveness of the jaws. The temporal is represented by two muscles, one of which, the pretemjjoralis, fig. 142, e, has its origin extended forward into the orbit from lieneath the })Ostfrontal, whence its fibres pass oljliquely l^ack- ward: the larger temporalis, ib. f, is attached to the parietal, the mastoid, and tympanic, and its fibres pass vertically external to those of the pretemporal, to be inserted into the coronoid and surangular. The pterj/goidei are larger muscles than the tem- porales; the one from the ectopterygoid, fig. 142, /«, receives an accession of fibres from the long pterygoid bone, and, passing obliquely backward, swells out into almost a hemi- spheric prominence at its insertion into the outer side of the angxdar elements at li.
