Summary

A new record of an early retiolitid, Reteograptus sp., from the topmost Llanvirn strata of Abereiddi Bay, South Wales, is described and figured. An approximately contemporaneous upper Darriwillian form from Gisborne, Victoria, Orthoretiolites? speciosus (Harris) is redescribed and shown to differ radically from both Reteograptus sp. and R. geinitzianus Hall, the type species of the genus.
