The flattened dorsal surface of the post-temporal is ornamented with raised bony tubercles. The supracleithrum is expanded and overlaps the upper end of the cleithrum. The lateral face of the supracleithrum is ornamented with a few weak ridges. The cleithrum is sigmoid in shape with its anterior edge produced medially. The endo- skeletal girdle attaches to the internal face of the cleithrum. The scapula contacts the cleithrum laterally, the coracoid ventrally and the mesocoracoid antero-medially. A large scapular foramen perforates the centre of the bone. Postero-dorsally the scapula has a prominent facet with which the anterior fin ray articulated. The remainder of the posterior edge is grooved. The coracoid is much larger than the scapula and considerably expanded antero-ventrally. SCO cor 10mm Fig. 62. Halec euplerygius (Dixon).
