Abstract
Four psammocinian species(Demospongiae: Dictyoceratida: Irciniidae) are described from Gageodo and Jejudo Islands, Korea. Among them, three are new species, Psammocinia rana, P. massa and P. vermins, which are very different from other recorded species. Secondary fibres of Psammocinia rana are mostly wide platelike shape with large perforation. Primary and secondary fibres of Psammocinia massa are lumped together in a thick mass through numerous areas. Psammocinia vemis is similar to P. mosulpia in skeletal structure, but differs in size of cored sands in primary fibres. The fourth species, we reclassify from Ircinia chupoensis to Psammocinia chupoensis based on more detailed observation of the skeletal structure. Ircinia only has sand cored primary fibres, while the observed species, has sand cored primary and secondary fibres.
