disk sub-pentagonal (d.d. 8.3 mm). Arms at least four times disk diameter. Disk covered with thin scales, many carrying a spinelet. Spinelets long, hollow, rugose, with tip of spinelet produced into a smooth point, sometimes with two or three small pointed spires; spinelets in middle of disk finer than those on the periphery or in the interbrachial region. Radial shields exposed, approximately triangular in shape; each shield pair separated along whole length; length extending slightly shorter than a quarter of the disk diameter. Ventral interbrachial area covered with small scales. Spinelets present but shorter and with a lower density than aboral surface.

Second oral tentacle pore emerging superficially onto the surface of the jaw. Oral tentacle scales larger than oral papillae, four to five in number, often longer than high with a rounded free edge; tentacles scales superficial situated on oral surface and separated from oral papillae.

Ventral arm plates approximately rectangular with a convex distal edge, contiguous on proximal arm segments. Tentacle pores covered, on the proximal segments oval scales, slightly pointed and often of different sizes; each pore with three scales arranged around the first two to four arm pores, decreasing to two thereafter until nearly the end of the arm; two scales comprised of a large glassy, slightly pointed, almost leaf-like scale sitting over a smaller inner scale. Lateral arm plates flared forming a ridge along the area where arm spines inserted. Arm spines six, up to three arm segments in length on proximal arm segments becoming shorter on distal ones; not quite forming a continuous row on the first free arm segment. Dorsalmost spines finely rugose, slightly flattened; ventralmost spines shorter, wider at the base of the spine, much flatter developing a saw-like edge with distinct teeth, terminating in triple-tipped spine; tip of arm spine glassy. These ventralmost spines become shorter on outer arm segments forming a row of large teeth along the ventral edge on the outer part of the arm spine.</paragraph>

, do not have thickened skin over the oral surface so the plates are clearer. Oral shields are more rounded slightly wider than long. Jaws with three to four oral papillae which are slightly more rugose than in larger specimens. However in other characters, such as tentacle scale number and arrangement, smaller specimens resemble the larger, although the gap between the oral papillae and oral tentacle scales is more obvious. Oral shields triangular slightly more elongated and rounded. Dorsal arm plates on smaller specimens are triangular with a convex distal edge and are separated, not contiguous. Often just two tentacle scales The number of scales may be the result of a larger scale being split perhaps during development thus resulting in three scales not two.
