6. Bergquistia baculus View in CoL n. sp. ( Figs. 8, 9)

Type specimen. Holotype (NIBRIV0000811393), Korea: Songaksan, Daejeong-eup, Seogwipo-si , Jeju-do, 21 Oct 1998, Lee KJ, by SCUBA diving, Depth 20 m, deposited in the NIBR.

Description. Thick encrusting mass sponge, size up to 8 × 5 × 2 cm. Winding surface covered with filamentous membrane with thick strong collagen and sharp conules. Oscules, rare, 1.5 mm in diameter. Colour in life dark beige. Texture firm and compressible.

Skeleton: Primary fibres without branches, 150-300 μm in diameter, simple long line, but rarely connected with secondary fibres and not heavily covered with filaments. Secondary fibres, 50-150 μm in diameter, rarely branched off from the primary fibres, broad plate-like secondary web appeared at choanosome ( Fig. 8G). Filaments, 1-2.5 μm in diameter, not clear terminal knob.

Etymology. This new species name, baculus , is named after the stick shape of long primary fibres near the surface.

Remark. Primary fibres of this new species are not branched except near conules ( Fig. 8D). Secondary fibres are very rare, but web type of secondary fibres is only shown at the choanosome ( Fig. 8G). They have a very broad plate-like shape.
