Two new marine species of the family Halichondriidae, Ciocalypta sasuensis n. sp. and Epipolasis maraensis n. sp., are collected from Chujado Island and Jejudo Island, Korea during 2000-2005. Ciocalypta sasuensis n. sp. is closely related to C. penicillus(Bowerbank, 1864) in the type of shape and ectosomal skeleton. However, C. sasuensis n. sp. is larger than Ciocalypta penicillus. Epipolasis maraensis n. sp. is similar to E. suluensis(Wilson, 1925) in the type of skeleton, but is different in size of spicule and growth form. Its oxeas and raphide are smaller than E. suluensis's. The growth form of this new species is semispherical and massive, but E. suluensis is lamellated.

Two new marine sponges in the family Halichondriidae, Halichondria gageoenesis n. sp. and Halichondria muanensis n. sp. are collected from Gageodo Island and Yongjeong-ri, Hyeongyeong-myeon, Muan-gun, Korea during 2006-2007. H. gageoenesis n. sp. is similar to H. oshoro(Tanita, 1961) in type of spicule, but is different from the latter in growth form and size of spicule. The oxea of the new species is larger than H. oshoro's. The growth form of H. gageoenesis n. sp. is thick and consists of encrusting with numerous erect hollow cylindrical tubes, but H. oshoro is of massive form. H. muanensis n. sp is similar to H. retiderma(Dendy, 1921) in type of spicule and choanosomal skeleton, but it is different from the latter in growth form and size of spicule. The oxea is smaller than that of H. retiderma. The growth form is thick and consists of encrusting, with numerous erect hollow cylindrical tubes, compared with the massive lobose of H. retiderma.
