discussion
Remarks. The rhopalasters correspond well in size and form with those of the type specimen: 300 – 400 µm in diameter with 6 terminal rays on short principal terminals. The discohexasters are within the same size range (measured by Reiswig & Kelly 2011 as spherical: 38 – 93 µm diameter and stellate 31 – 84 µm in diameter). The pentactins are of similar size (measured by Reiswig & Kelly 2011 as tangential ray length 191 – (281) – 384 µm, proximal ray length 313 – (450) – 560 µm). We did not find any oxyhexactins in our specimen, it is noted in the type description that these occur irregularly and the small size of our specimen may have resulted in them being missing.
