Notes
It is possible that the creature actually sighted by Stiasny was the new species of Netrostoma awaiting description; however, this seems unlikely because it would be difficult to mistake a single large central knob for "about 10 wart-like projections", or lack of appendages on the arms for "two kinds of appendages between the mouths". However, Kramp (1965) did make this error (Gershwin & Zeidler, in press).
While it is clear that a new species of Netrostoma exists in Queensland waters, it is less clear whether N. coerulescens is also present in Australia.
