Two marine species of family Callyspongiidae, Callyspongia mookriensis n. sp. and Siphonochalina truncata, were collected from Chujado Island and Jejudo Island, Korea during 2005-2007. Callyspongia mookriensis n. sp. is similar to Callyspongia flabelliformis Tanita, 1968 in type of spicule, habitat and growth form but differs in spicule and mesh size. The new species has longer oxea and broader mesh than Callyspongia flabelliformis's. The overall shape and skeleton of Siphonochalina truncata are nearly identical with specimens described by Lindgren (1897).

A new marine sponges, Mycale (Carmia) ieoensis n. sp., of the family Mycalidae was collected SCUBA diving in June 2017 from Ieodo Ocean Research Station, Korea. M. (C.) ieoensis n. sp. is encrusting to irregular massive type, yellow in life. This new species is similar to M. nullarosette Hoshino, 1981 in color and growth form but it differs in spicule size and sigma shape. Spicule size of M. (C.) ieoensis n. sp. smaller than that M. nullarosette. Also, M. (C.) ieoensis n. sp. has two size toxa, but M. nullarosette is not. The new species are compared to other Mycale species from the Korean region, and similar species from elsewhere.

Two adult rock partridges raised in a city zoo were examined parasitologically and pathologically. Two distinctive eggs resembling those of Capillaria and Heterakis were detected in the feces. At necropsy, a markedly-dilated duodenum with severe catarrhal exudates, containing adult worms of Capillaria sp. and Heterakis sp. in the cecum, was observed. Male Capillaria had the cloacal aperture extended almost terminally with a small bursal lobe and an unsheathed spicule with transverse folds without spines. Female Capillaria had a vulva that was slightly prominent and slightly posterior to the union of the esophagus and intestine. The esophagus of the adult Capillaria was more than a half as long as the body in the male, but was much shorter in the female. Based on these morphological features, the capillarid nematode was identified as Capillaria obsignata. The male adult worms of Heterakis was identifiable by 2 dissimilar spicules, a unique morphological feature where the right spicule was considerably longer than the left, which is also a characteristic feature of Heterakis gallinarum. This is the first report of concurrent infections with C. obsignata and H. gallinarium in rock partridges.

Ingrowing toenail has been treated conventionally by various surgical treatment modlities. However, none of these procedures are perfect to achieve esthetic results with low cost, recurrence, and complication rates. Although mild cases can be treated conservatively, in severe recurrent cases, surgical treatment is preferred. The purpose of this study is to evaluate the effectiveness and safety of using partial matricectomy and paronychial advancement flap for correction of recurrent ingrowing toenail. Eight patients suffering from recurrent ingrowing toenail were operated using partial matricectomy and paronychial advancement flap in our department from August 2004 to August 2005. The number of recurrent episodes ranged from 2 to 5. With digital nerve block, the excision area was marked on nailplate and inflammed lateral nail fold. The horizontally designed paronychial flap considering defect size was effective for wide exposure of the neighboring germinal matrix, which is later to be completely excised or cauterized because remnant germinal matrix made postoperative spicule formation. The nailplate on the affected side was removed about 3-5 mm width longitudinally, being cautious not to damage the proximal dorsal nail fold. The same width of the sterile matrix including germinal matrix was excised longitudinally with inflammed granulation tissue and partial lateral nail fold on the affected side. The subcutaneously elevated paronychial flap was advanced to cover the defect and was anatomically sutured with 5-0 nylon sutures. We evaluated our procedure's effectiveness by examining some factors such as cosmetic results, recurrence, spicule formation, postoperative pain and duration of return to normal activities. In eight patients, no complication was observed such as recurrence, severe pain and spicule formation except for 1 case of infection. Postoperative discomfort was minimal. Average duration of return to normal activities was 12 days. Cosmetically the results were acceptable in all patients. The partial matricectomy and paronychial advancement flap for correction of recurrent ingrowing toenail were found to be technically simple, efficient procedure with a relative low recurrence rate and better cosmetic results.

Two new species belonging to genus Mycale are described from the waters around Geojedo Island and Gageodo Island, Korea. Mycale (M.) geojensis n. sp. seems close to M. (M.) adhaerens parvasigma Hoshino, 1981, but our new species has three categories of anisochelae. M. (Aegogropila) hentscheli n. sp. is closest to M. (A.) obscura (Carter, 1882) in shape and spicule, but has no large sigma.

A taxonomic study on marine sponges was conducted with materials collected from Gageodo Island, Korea, from August 1999 to July 2001 by SCUBA diving. Among them, Phorbas gukhulensis n. sp. is new to science. Phorbas gukhulensis n. sp. is similar to P. fitictius Pulitzer-Finali from which it differs in spicule size and growth form.

Two species in the genus Stelletta, Stelletta crusta n. sp and Stelletta maxima Thiele, 1898 have been Collected from Geomundo Island. Stelletta crusta n. sp is similar to Stelletta tetrafurcata Hoshino, 1981 in the clade of the dichotriaenes which is trifurcate or multifurcate but both species differ in spicule size and composition. Stelletta maxima is first recorded in the Korean fauna.

A new marine sponge in the family Tethyidae, Tethya uljinensis n. sp. was collected from Uljin, Korea in 2007. Halicometes koreana in the family Tethyidae was redescribed. Tethya uljiensis n. sp. is closely to Tethya simi. in skeletal structure and spicule composition. But, it differs in the size of spicules(stronyloxea) and shape of oxyaster.

A new sponge species of the genus Hymeniacidon (family Halichondriidae) from Munsum, Jeju Island, Korea is described. This species is similar to H. sinapium in spicule size, but the color, oscules, external surface and arrangement of the spicules are considerably different. This species is bright yellow in live, and retains multiple oscules and a plumose bundle of styles in the subectosomal region.

Chelonaplysilla supjiensis n. sp. belonging to family Darwinellidae was collected from Jejudo Island, Korea in 2008. C. supjiensis n. sp. is closely to C. noevus in surface structure and skeleton, but differ in surface, sandy reticulation mixed with many spicule detritus. This study is a new record of genus, family and order in Korea.
