Regan 07i the Anatomy and Other features of the head skeleton are shown by thefigures, and it need only be remarked tliat the form of thecranium, the development of the temporal fossse, the generalcharacter and arrangement of the frontals, parietals, the oticbones, the nasals, circumorbitals, and supraniaxillaries indi-cate a pretty close relationship to generalized isospondylousfishes such as Elops [cf. Ridevvood, P. Z. S. 1904, ii. pp. 35-81, c. figg.). The vertebral column only differs from that of the Elopidaein that the centra are coossified with the arches ; there are52 vertebrae ; the centra are perforated ; the ribs and epi-pleurals are inserted together on very short processes whichincrease in length posteriorly
