Some polyclad turbellarians new to the fauna of the Australian coasts

Abstract

This paper is a contribution to the knowledge of the polyclad turbellarians of the Australian coasts. Of the eleven species encountered and belonging to five known genera, one acotylean, Hoploplana rosea, and three cotylean species, one Acanthozoon and two Pseudoceros, are new, whilst six species have been described hitherto, but are new to the Australian fauna. Two specimens of the remaining form are very young, but appear to be unidentifiable stylochids.
