Description. Centrodorsal thin discoidal, circular or pentagonal in aboral view, 3–5 mm across, 0.7–1.2 mm thick, with cirrus sockets in 1–2 irregular rows. Cirri XVI–XXVI, 12–24, 8– 13 mm long. Longest cirrals (5 th –7 th) 1.2–1.5 times longer than wide; cirrals beyond 7 th with aboral spine. Radials almost wholly concealed by centrodorsal.
