(Fig. 79, 80) Occurrence : Sosua (Dominican Republic), 19 April 1964. Holotype; msng 47708 This small specimen was light violet in life, elastic. The ectosomal skeleton, not separable, is a plurispicular reticulation with meshes 180-380 ^m wide. The fibres, 15-30 [j-m thick, are made by megascleres bound by clear spongin. Abundant sigmas are also present. The choano- somal skeleton is a dense reticulation of 10 to 35 [xm-thick fibres in which spongin predominates as they are mostly cored only by one or two spicules in front. The meshes are irregular, 90-180 [xm Fig. 79 - Gelliodes sosuae sp. n., the holotype.
