  • Two new species of the genus Burmoniscus collinge, 1914, B. ifugaoensis and B. taitii are described from Banaue and adjacent area, mountainous district in the northern Luzon, the Philippines. B. ifugaoensis is morphologically similar to B. novabritannicus(Vandel, 1973) and B. yunnanensis Kwon and Taiti, 1993, but is distinguished by the much elongated distal part of male pleopod 1 exopod and the peculiar setation on the distal part of male pleopod 1 endopod. B. taitii is similar to B. punctatus Taiti, Ferrara and Kwon. 1992 in the shape of male pleopod 1 endopod, but is easily distinguished by the peculiar coloration of male, the morphology of cephalon, and the shorter distal part of male pleopod 1 exopod.

  • Some siphonophores and scyphomedusae were collected from the coasts of Hoopo(Sea of Japan) and Geojedo Island, Changson(Korea Strait) in Korea respectively. They identified into Porpita umbella O. F. Muller, 1776 of the order Siphonophora in the Hydrozoa and Dactylometra quinquecirrha L. Agassiz, 1862 of the Semaeostomeae in the Scyphozoa. P. umbella looks like a bule button. It's chitinous float is light brown and the other body protions are turquoise blue. D. quinquecirrha has four long curtain-like oral lobes which are highly flexible and ornamented with numerous nematocyst warts, and 32 radiating reddish brown stripes upon exumbrella. The Siphonophora is reported for the first time and three scyphomedusae are reported in Korea so far.

  • Electrophoretic method is and morphometric analysis were used to examine genetic and phenetic variation among 16 populations of Rhabdophis tigrina and to clarify the subspecific status of R.t.tigrina and R.t. lateralis in Korea. The degree of genic variation based on 23 presume loci was moderate and was similar to those found for other vertebrates. Interpopulation levels of genic differentiation were slight for all populations studied and overall genetic similarities were =0.970. The number of ventral and subcaudal scales showed clinal variation with increasing tendency in numbers toward south . Discriminant function analysis based on six morphometric characters revealed that there were no morphometric differentiation between two subspecies, therefore it was concluded that they were same taxon and R.t. lateralis (Berthold, 1859) should be treated as synonym of R. t. tigrina(Boie, 1826)

  • Two species of Moroco oxycephalus and M. lagowskii were studied to examine patterns of genic variation and morphological difference within and between populations of two species, and to clarify their taxonomic status and geographic distribution. The number of scales above lateral line(SAL) was the key character to classify these species. On the average, M.lagowskii had 22 or more SAL whereas M.oxycephalus had 20 or less. Previously known character of the position of dorsal fin was found to be not appropriate to distinguish them. Five loci, Gp, st-1, Est-2, Est-3 and Got-1 , showed fixed difference electrophoretically between two species and these could be used as genetic markers to identify them. The degree of genic variation of M. oxycephalus was four fold higher(H=0.032) than that of M. lagowskii(H=0.008) but both species were far less than the average genic variation of freshwater fish in general. Rogers' genetic similarity coefficients between two species were S=0.692 and their presumed divergent time was estimated to be sbout 1.8million years ageo. Detailed survey of the geographic distribution of thses revealed that M.lagowskii was distributed in northeastern part of South Korea(Ganseong , Gangreung, Wangsan, and Oggye) and M. oxycephalus was occupied rest of the peninsula. The distrance between Oggye, the southern limit of M. lagowskii distribution , and Samwha (near Samcheog), the northern limit of M.oxycephalus, was aobut 15 Km apart and no symparty was found in between.

  • A taxonomic study was carried out on the freshwater copepods of Order Calanoida from Korean during the period from May, 1983 to November, 1984. Materials consist of both specimens deposited at the Department of Biology, Kangreung National University and the specimens collected from various freshwater regions (excluding the subterranean waters) such as rivers, lakes, ponds, bogs, ricefields, etc. during this period. As a result of examining the specimens collected at the 26 localities in South Korea, 8 species of 3 families were identified, of which 4 species are newly known from Korea ; Sinocalanus sinensis (Poppe, 1889) ; Tropodiaptomus oryzanus Kiefer , 1937 ; Sinodiaptomus sarsi (Rylov, 1923) ; Neodiaptomus schemackeri(Poppe et Richard, 1892).

  • Genetic and morphological variation among seven populations of two species of the genus Liobagrus that had been collected from six separate river systems in Korea were analyzed by means of starch electrophoreiss and discriminant function analysis . The degree of genic variation among three population of L.andersoni was P=21.3%, H=0.068 , and that of four population of L.mediadiposalis was P=16.3%, H=0.560. Rogers' gentic similarity coefficient (S) of L.andersoni and L.mediadiposalis were S=0.592 , S=0.675 respectively. In morphometric characters of L. andersoni, the population from Kum River was distinctly different from other conspecific populations.

  • Some hydromedusae were collected from Shiwhaho (Kyonsgi-do), Korea Strait and Yeosu, Korea during years 2000-2002. They were identified into Sorsia tubulosa (M. Sars, 1835) of the order Anthomedusae, and Liriope tetraphylla (Chamisso and Eysenhardt, 1821) of the order Trachymedusae respectively. They are new to the Korean fauna. The order Trachymedusae is first recorded in Korea. The long tube-like manubrium and four marginal tentacles are characteristics of S. tubuloso. In L. tetraphylla, the four triangle-shaped gonads and their positions upon half of surface of subumbrella, the seven blind centripetal canals in a quadrant and the long fat manubrium are its distinct characteristics. Resulting from this work, the Korean hydromedusae identified so far consist of 13 species of 11 families in five orders.

  • Six smittinid species were identified from Korean waters. Two of which were previously recorded in the Korean bryozoan fauna are reviewed. Parasmittina raigii (Audouin, 1826) reported from Gwabutan, Jeju Island is re-examined and reidentified as Parasmittina serrula Soule and Soule, 1973, which is new to the Korean fauna. Smittoidea reticulato (MacGillivray, 1847) is reported as species which doesn't occur in the Pacific Ocean Accordingly, Smittoidea reticulata should be deleted from the Korean bryozoan fauna and the Korean specimen identified as Smittoidea reticulata is synonymous with Smittoidea pacifica Soule and Soule, 1973. Fourteen smittinid bryozoans from Korea are thus recorded so far.

  • Two echiniscoid belonging to genus Anisonyches are recorded from the intertidal or shallow sublittoral coralline sands at Santacruz Island, Mindanao, the Philippines: A. deliquus n. sp. and A. diakidius Pollock, 1975. A. deliquus n. sp. is related to A. mauritianus in the absence of primary calvae and sensory papillae on leg IV with their characteristic claw formation, but discernible from the latter species in the absence of sensory spine on each of the first three leg pairs. We provide some remarks on the two claw types of the genus Anisonyches, that is, diakidius-type and mauritianus-type.

  • 190 species in 82 families of marine fishes were collected from 6 survey stations along the southwestern coast of Korea, from April 1996 to March 1997. A checklist of fishes from southwestern coast of Korea was given with their records of the specimens in the present investigations. Analysis of fish species compostion in this areas showed that the family Gobiidae was the most abundant and Scorpaenidae was the next. The fishes living in this area were under the influence of the Tsushima warm current and the Yellow Sea. Among them, Tridentiger trigonocephalus, Repomucenus valenciennei and Thryssa adela were commonly found from the each sites, and Chirolophis wui, Pholis fangi, Repomucenus koreanus, and Acanthogobius luridus are endemic speices of the to Yellow Sea.
