M. browni has been described by Brough (1931 : 262-266). A new restoration of the skull is given here (Fig. 32) to include additions and amend- ments . The opercular has a curved ventral border ( 312, Fig. 33); the posterior border of the subopercular is pectinated and its surface ornamented with small spines. The preopercular has a more strongly concave antero-ventral border than is shown in Brough's figure (1931 : text-fig. 11). In addition to the usual preoper- cular sensory canal, there is a long horizontal branch extending across that bone (). The single triangular suborbital and the rectangular dermosphenotic have pectinated posterior borders. The dorsal side of the orbit is bordered by four supraorbital elements ( 304). These are deep and appear considerably fore- shortened in the restoration. ?ant. clav 4nnm I I I I I Fig. 33.
