Taxonomic comments. Poraniomorpha tumida View in CoL lacks spines on its actinolateral fringe/inferomarginal plates, although granuliform spinules similar to those elsewhere on the body, are present on the actinolateral/ inferomarginal plates ( Fig. 7 View FIGURE 7 E). This species possesses an abactinal surface covered by patches of tiny granuliform spinelets ( Fig. 7 View FIGURE 7 G) and has an actinal surface covered by either widely dispersed pointed granules or very tiny, pointed papilliform spinelets (length = 0.5 mm). Three to five furrow spines in transverse series are present.

Occurrence. North Atlantic, West coast of Greenland, north and east coasts of Iceland, northeast of the Faeroe Channel, Denmark Strait, Jan Mayen Island, near Spitsbergen and northern Norway, throughout the Barents Sea, Kola Bay, White Sea and Kara Sea north to about 82º. The Laptev Sea, East Siberian Sea east to 161ºE. Hudson Bay, Beautfort Sea. 9–1203 m (30–300 according to Djakonov 1950).
