7. Bergquistia ramus View in CoL n. sp. ( Figs. 10, 11)

Type specimen. Holotype (NIBRIV0000554227), Korea: Hyungjesum, Sagae-ri, Andeok-myeon , Seogwipo-si , Jeju-do, 2 Oct 1998, Lee KJ, by SCUBA, Depth 20 m, deposited in the NIBR.

Description. Round mass sponge, size up to 7 × 5 × 3.5 cm. Surface covered with distinct sharp conules and strong collagen filamentous membrane. Oscules, 1-4 mm in diameter. Color in life dark beige. Texture firm and compressible.

Skeleton: Long primary fibres, 200-500 μm in diameter, simple twisted or entwined pattern fascicles. Several primary fibres bound with thick fascicles at base. Long nuddle-like branched primary fibres are similar to secondary fibres. Secondary fibres, 100-250 μm in diameter, short bridged pattern. Thin filaments, 0.3-1 μm in diameter, terminal knob very rare, 3-4 μm in diameter.

Etymology. This new species name, ramus , is named after the shape of thick primary fibres divided into several thin primary fibres near the surface.

Remark. This new species is very unusual, thick primary fibres of this species divided into several thin primary fibres. The ends of primary fibres are divided into three branches near conules ( Fig. 10F).
