Holotype BMNH 82.12.23.399 Challenger Station 219, Admiralty Is, 274 m.

Main Features: The disc is covered with smooth plates and larger, separated radial shields. There are large interradial plates with two longer than wide plates between it and the central rosette. Dorsal arm plates small, triangular, wider than long. Lateral arm plates slightly tumid, with 3–4 small arm spines (note: the arm spines are absent from about halfway up the arms in the holotype). Two large ventral arm plates excavated each side for two pairs of exposed tentacle pores, each with an elongated scale. Distal ventral arm plates very small. Large, proximally pointed oral shields adjoining the interradial plate.
