    Five species of the genus Psammocinia (Irciniidae) are described from Chejudo Island, Namhaedo Island and Wando Island, Korea (Psammocinia jejuensis, P. mosulpia, P. mammiformis, P. samyangensis and P. wandoensis). Psammocinia is characterised by large quantities of sand in spongin fibres, mesohyl matrix and as a thick superficial cortex. In addition to the primary and secondary branching fibres, fine filaments emerge from individual pores in the fibres. Occasionally short secondary fibres are connected to large sand grains, forming bridges between adjacent sand grains. The skeleton formed from sand grains associated with fibres provides additional support for the body of the sponge.
