Cephalon subquadrate to subcircular in outline, about 87% as long as wide, nonspinose, strongly convex; border wide (sag., exsag.), flattened; border furrow well developed, moderately narrow (sag., exsag.); preglabellar median furrow shallow, short (sag.), moderately narrow (tr.). Glabella 71 to 75% (mean 72%, n = 5) as long (sag.) as cephalon. Small anterior lobe clearly defined, subpentagonal to semiovate in shape, obtusely angular anteriorly, occupying 32 to 38% (mean 36%, n = 6) of glabellar length. F3 shallowly incised, bowed moderately rearward; posterior glabellar lobe weakly tapered, strongly convex in its posterior half, less so anteriorly. F2 furrows slightly anterior of glabellar mid-length (sag.), weakly developed as faint notches, gently directed anteriorly for a short distance. F1 furrows effaced to weakly developed; glabellar node indistinct, located slightly posterior of F2 furrows; basal lobes small, subtriangular in outline.

); a pygidial axis that is constricted (tr.) around M2 and expands (tr.) in the posteroaxis; and a wide posterior border furrow. Only the absence of a node just posterior to F2 on the posteroglabella and the presence of finely granulose ornament differentiate the Goyder Formation material. As the posteroglabellar node and ornament is often difficult to discern in the considerably smaller Antarctic specimens (Jago & Cooper 2005, fig. 2A, B, E, F, H, I), it is likely these differences represent ontogenetic variation. The posteroaxis on the pygidium in the
