Figures 83–88 Type locality: Alaska, Aleutian Islands, Andreanof Islands, S of Amatignak Island (51 º 11.935 N, 179 º 05.87 E), 95 m. Type material: Holotype, LACM 2004 - 279.001 (leg. R.N. Clark, 4 July, 2004; trawled R/V Sea Storm, 95 m) (NMFS 143 -0401- 110). Diagnosis: Large, slender stars; disc small, rays very long, slender; abactinal surface covered with a thick, cuticle-like epidermal layer; aboral plates small, close-set, bearing 6–12 pointed spinelets; Color violet abactinally, pale yellow-cream actinally. Description: Large, long, slender rays, R to 21.3 cm, r 2 cm, R:r 10.65: 1 (Figs. 83 & 84); disc small, rays very long, slender, gradually tapering. Abactinal surface (Fig. 85) covered with a thick, purple, almost cuticlelike epidermal layer which completely obscures the abactinal plates. Abactinal plates small, round or oblong, crowned with five to ten short (0.5 mm), bluntly pointed spinelets; abactinal plates close set, forming a very fine reticulation with small papular areas, each with a single papula; madreporite small, about 3 mm in diameter, with irregular radiating ridges. Superomarginals about twice as long as wide, bearing three or four rows of 8–10, stout, sharp, thorn-like spines 0.4 mm in length; inferomarginals three times as long as wide, bearing three or four rows of 11–13 spines, similar to those of the superomarginals; intermarginals small, about the same size as abactinal plates, in a single series extending 20 % of R; two series of actinal intermediate plates, the first about half as large as inferomarginals, bearing three or four rows of six to eight sharp, thorn-like spines, about 0.4 mm long, and extending about 1 / 2 of R, where they become very irregular and mostly absent, to about 3 / 4 of R; second row much smaller, bearing five to ten similar spines and extending irregularly to about 20 % of R.
