A new variety, Lecanorchis japonica var. insularis (Orchidaceae: Vanilloideae), a mycoheterotrophic orchid from Jejudo Island, Korea, is described and illustrated. It usually grows with L. japonica var. japonica, L. japonica var. hokurikuensis and L. kiusiana in evergreen forests. The newly described variety is distinguished from L. japonica vars. japonica, hokurikuensis, and kiiensis by having fully opened, larger flowers and an obtuse labellum apex.

Holothuria pericax Selenka, 1867 belonging to the family Holothuriidae in the order Aspirochirotida of the subclass Aspidochirotacea is new to Korean fauna. This species was redescribed with figures based on the specimen collected at 16 m deep in north-west Munseom, Seogwipo. A key to the genus was presented. Fifteen species of holothuroids have so far been reported in Jejudo Island of Korea.

This study was carried out to investigate the possibility for utilization and the effectiveness of citrus byproducts on the nutritional composition and sensory score of Jejudo native pig meat. The groups are consisting of the Jejudo native pig loin without citrus byproduct ($JNP-T_0$) and the Jejudo native pig loin fed with 8% and 15% citrus byproduct during growing and fattening period($JNP-T_1$). The contents of moisture, crude protein, crude fat, crude ash, calorie, cholesterol content Mg, P, K, Na, vitamin $B_1\;and\;B_2$, total amino acid, and total free amino acid content were not significantly different between $JNP-T_0$ and $JNP-T_1$(p>0.05). It was found that palmitic acid($25.301{\sim}27.403%$) was the highest one among saturated fatty acid while oleic acid($42.234{\sim}43.061%$) was the highest among unsaturated fatty acid in both groups. In case of sensory score, the color and aroma of raw meat, and the flavor preference of boiled meat of $JNP-T_0$ were higher than those of $JNP-T_1$(p<0.05). But the taste, texture, juiciness and palatability of boiled meat were not influenced by feeding of citrus byproduct.

Two species of halacarid mites belonging to genus Copidognathus viz C. jejuensis n. sp. and C. polyporus Bartsch, 1991 are described on the basis of the specimens collected from an algal bed in Jejudo Island, Korea. Copidognathus jejuensis n. sp. is closely related with C. dentatus Viets, C. dentipes Bartsch and C. eblingi Chatterjee. Morphological similarities and dissimilarities among them are discussed. Copidognathus polyporus Bartsch is reported for the first time from Korea and away from its type localitiy. A key to the species of genus Copidognathus from Korea is provided.

This study presents a survey of the bryophytes of evergreen broad-leaved forest near Baekyaki Oreum in Gujwa-Seongsan Gotjawal in the eastern part of Jejudo Island, Korea. A total of 53 taxa belonging to Bryophyta (11 families 26 genera 39 species) and Marchantiophyta (9 families, 9 genera 14 species) were determined, and the liverwort index was found to be 26.4%. The predominant life-form was the mat type. The rates of bryophytes dominating at mesic to hygric sites were higher than those of bryophytes, which were mainly observed in xeric habitats. These values indicate that the forest areas in this study area have a high density level. Upon an investigation of the substrates, bryophytes on rocks were most diverse. It was also found that volcanic rock masses of various sizes lay scattered over the study area and offer numerous micro-habitats for bryophytes. This is related to the characteristics of Gotjawal. We consider that more detailed studies should be conducted on regional scales to establish the bryophyte flora of Gotjawal and the evergreen broad-leaved forests of Jejudo Island.

A single bothid specimen (113.9 mm in standard length) was collected by bottom trawl from southern Jejudo Island, Korea. It was easily identified as Kamoharaia megastoma (Kamohara, 1936), based on extremely large mouth. The species is characterized by maxillary extending beyond eyes, three pairs of long curved canines on lower jaw, tip of vomer projecting into mouth cavity, blackish pectoral fin, and blind side without lateral line. We described it as the first record to Korean fish fauna, and proposed the new Korean name, "Keun-ip-dung-geul-neop-chi" for this species.

This study presents a survey of bryophytes in a subtropical forest of Nabeup-ri, known as Geumsan Park, located at Aewol Gotjawal in the northwestern part of Jejudo Island, Korea. A total of 63 taxa belonging to Bryophyta (22 families 37 genera 44 species), Marchantiophyta (7 families 11 genera 18 species), and Anthocerotophyta (1 family 1 genus 1 species) were determined, and the liverwort index was 30.2%. The predominant life form was the mat form. The rates of bryophytes dominating in mesic to hygric sites were higher than the bryophytes mainly observed in xeric habitats. These values indicate that such forests are widespread in this study area. Moreover, the rock was the substrate type, which plays a major role in providing micro-habitats for bryophytes. We suggest that more detailed studies of the bryophyte flora should be conducted on a regional scale to provide basic data for selecting indicator species of Gotjawal and evergreen broad-leaved forests on Jejudo Island.
