Poraniomorpha tumida 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 E). This species possesses an abactinal surface covered by patches of tiny granuliform spinelets ( Fig. 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 ). Material examined.
