The variations of the shoulder-girdle in this genus will be noticed under the difi'erent species into which it has been found desirable to distribute it. Text-fig. 62. Shoulder-girdle of Mwmnosaurus 'lleedsi, (K. 3704, -J nat. size.) cor., coracoid ; gl., glenoid cavity ; , iuterclaviele ; , interscapular foramen ; sc, scapula. â The scapuloe (sc, PL VI. fig. 3 ; text-figs. 62, 67, 68), as in the other genera of the Elasmosauridse, are triradiate bones, each consisting of a posterior arm uniting with the antero-external angle of the coracoid, a dorsal arm extending towards the vertebral column, and a ventral expansion which, in the adult animal, meets its fellow in the middle line in a deep symphysial surface, which extends back to meet the anterior median prolongations of the coracoids. The posterior bar is thickened at its extremity, v/here it bears two facets, one for union with the coracoid, the other forming the anterior part of the glenoid cavity. The fiirsit of these facets looks backwards and
