A study on marine sponges was conducted by SCUBA diving at Ulleungdo Island and Gageodo Island, Korea during the period from July 2000 to October 2001. Two species, Clathria (Clathria) gombawuiensis n. sp. and Clathria (C) gageoensis n. sp., are new to the fauna of sponges. Clathria (C) gombawuiensis n. sp. closely relates to Clathria (C) conica Levi, 1963 based on the type of spicules, but differs in size of spicules and growth form, Clathria (C) conica has not small toxa. Clathria (C) gageoensis n. sp. is similar to Clathria (C) hexagonopora Levi, 1963, but it differs in size of spicules and growth form, also Clathria (C) hexagonopora has not small toxa.

Specimens were observed by light microscopy (Carl Zeiss Axioskop II) and scanning electron microscopy (SEM, HITACHI S-3000N). The identification was performed on the basis of external features, shape, structure of skeleton, and size and form of spicules. The thin free-hand section was made by specimen hardened in alcohol using a surgical blade in order to observe the structure of skeleton.

Type specimen. Holotype (Por. 55), Binjibak (Gageodo Island), 24 Jul 2000 (K. J. Lee), by SCUBA diver from 20 m in depth, deposited in the HUNHM. One Paratype (Por 55-1), Binjibak (Gageodo Island), 24 Jul 2000 (K.
Spicules were prepared by dissolving a piece of sponge in sodium hypochlorite and examined with SEM (Hooper, 1996, Rutzler, 1978). The holotypes are deposited in the Natural History Museum, Hannam University (HUNHM) Daejeon, Korea.
The subgenus Clathria is only a single category of auxiliary style forming a sparse paratangential ectosomal skeleton; choanosome without marked difference between axial and extra-axial region (Hooper and Van Soest, 2002). The samples were collected from Gageodo Island and Ulleungdo Island, Korea during the period from July 2000 to October 2001 by SCUBA diving. They were fixed at once in 99.

) hexagonopora. The acanthostyle of new species is three times as length as Clathria (C.) conica, and large toxa is half of them. Also Clathria (C.
This new species is similar to Clathria (C.) conica Levi, 1963 based on the types of spicules (Levi, 1963), but the new one is distinguished from growth form and size of thick styles. The growth form is thick flatten in this species, but mass in Clathria (C.
