Two species of the family Chalinidae, Haliclona (Gellius) tubulensis n. sp. and Haliclona (Gellius) marismedi were collected from Hongdo Island and Gageodo Island, Korea during 2004-2007. H. (G.) tubulensis n. sp. is closely related to H. (G.) coreana in type of spicules and growth form. But it is different in size of toxas and oscules. Toxa of H. (G.) tubulensis n. sp. is one type and its oscules are tuberculated. The toxa of H. (G.) coreana is two types and lacks projections. The overall shape and spiculation of H. (G.) marismedi are nearly identical with specimens described by Pulitzer-Finali (1977).
