Sarcotragus schmidti n. sp. ( Fig. 3 ) Type specimen. Holotype (NIBRIV0000325791), Korea : Marado Island , Daejung­eup , Seogwipo­si , Jeju­do . 4 Nov 2000 , Lee KJ , by SCUBA , depth 21 m , deposited in the NIBR . Description. Round mass, size up to 10.5 × 6 × 3.5 cm . Conules, difficult to distinct except at the side of sponge because many other animals attached on sponge surface. Thick filamentous membrane with fine branched fibres. Colour pale gray in life. Texture soft and compressible. Skeleton: Primary fibres, strongly braided longitudinal fascicles, and fine meshed net like bark of tree. Primary fibres’s diameter, diverse, 300-700 μm, thin primary fibres confused with secondary fibres. Cylindrical primary fascicles filled with wads of filaments. Secondary fibres with porous branch, 50­150 μm in diameter, secondary web, 800 μm in diameter. Filaments, 5-7 μm in diameter, terminal knobs, 15 μm in diameter. Filaments difficult to separate from fibres. Etymology. This species name schmidti is named after Schmidt who erected this genus Sarcotragus . Remark. This new species is characterized by strongly braided longitudinal primary fascicles with fine meshed net.
