OBSERV. This genus represents, in Australia, the group of Phry- 

 nocephali, to which it belongs as a distinct type. The cephalic plates

 the back, their anterior margin being thicker and elevated, whilst the 

 posterior margin is thin, and slightly covered over by the adjacent 

 plates or scales, as the case may be.

CHAR. SPEC. Scutis supralaUalibus in ires series ordinatis, quam 

 labiales minoribus ; infralabialibus exiguis, item in ires series ordi-
