Amphilichas sp.

Fig. 6F .

Material.—One cranidium (repository number NIGP−152000).

Remarks.— Amphilichas from Tasmania ( Edgecombe et al. 2004: fig. 11A–C; Edgecombe and Webby 2007: fig. 5B–D) shows resemblance to this cranidium. This incomplete glabella however differs in having an anterior margin that is slightly curved backwards sagittally and sharply curved longitudinal furrows. The specific identification cannot be completed, because of incomplete preservation as well as paucity of specimens.
