A single specimen (700 mm in disc length) of Plesiobatis daviesi, belonging to the family Plesiobatididae, was firstly collected in the north-eastern coastal waters of Jejudo Island, Korea by using a bottom trawl on 24 October 2010. This species was characterized by having five pairs of gill openings, tail with one to three large spines, long snout length, long caudal fin, and pleated margin of nasal curtain. It is morphologically similar to Urolophus aurantiacus, but the former is distinguished from the latter by having longer caudal fin and snout length. We add P. daviesi to the Korean fish fauna and suggest the new Korean names, "Gin-kko-ri-huin-ga-o-ri-gwa", "Gin-kko-ri-huin-ga-o-ri-sok" and "Gin-kko-ri-huin-ga-o-ri" for the family, genus and species, respectively.

Seasonal variation in species composition of estuarine fauna in the Han River estuary was determined by analyzing monthly samples collected on the intertidal flat of Ganghwa Island by a fence net from April to December 2009. Total number of species was 57: 34 species of fishes, 20 species of crustacean, 2 species of cephalopods and 1 species of jellyfish. Of a total of 57 species, Portunus trituberculatus (57.2%), Palaemon gravieri (7.1%), Collichthys lucidus (7.0%), Hemigrapsus sanguineus (6.2%) and Exopalaemon carinicauda (4.7%) were predominated in abundance. Diverse species were occurred in spring and autumn, and abundance was high in autumn. Chelon haematocheilus, Synechogobius hasta, Co ilia nasus, P. gravieri and E. carinicauda were classified as the brackish residence species. P. trituberculatus, C. lucidus, Mugil cephalus and Cynoglossus joyneri were coastal migratory species which use the estuary as nursing and feeding grounds. Diadromous species (such as Takifogu obscurus, Anguilajaponica and Eriocheir sinensis) and freshwater fish (Carassius auratus) were also collected.

This is the first report of Cantherhines pardalis (Tetraodontiformes: Monacanthidae) from Korea. A single specimen (105.4 mm in SL) was collected from the coastal waters of Busan by gill net on 20 June, 2012. This species is characterized by having the following morphological traits: II, 34 dorsal fin rays; 31 anal fin rays; 13 pectoral fin rays; caudal peduncle without large spines; spine row on the lateral side of first dorsal spine distinct; posterior end of pelvic with encasing scales distinctly more protruding than ventral flap. This species is similar to C. dumerilii except for the number of spines on caudal peduncle (none in C. pardalis vs. two pairs in C. dumerilii). Based on morphological and molecular approaches, the specimen was identified as C. pardalis. We add C. pardalis to Korean fish fauna and propose the new Korean names "Yuk-gak-mu-nui-jwi-chi" for the species.

Three specimens (56.7~92.4 mm in standard length) of the small psychrolutid Psychrolutes pustulosus (Schmidt, 1937) were collected by bottom trawl in the coastal waters off Pohang, the southern East Sea, Korea. This species is characterized by large cephalic pores, no markings on the body or fins, no spines on the head, and no notch between the spiny and soft-rayed dorsal fin. We describe specimens the southernmost distribution in the world, and compare them with two congeneric species from Russia. We thus present the first record of Psychrolutes pustulosus (Schmidt, 1937) within the Korean fish fauna and propose the new Korean name "Min-mu-nui-mul-su-bae-gi" for this species.

Six specimens (151.4~171.2 mm in standard length) of the poacher Aspidophoroides monopterygius were collected by Danish seine net in the coastal waters off Samcheok and Gangneung, the East Sea, Korea. This species is characterized by a slender body, one dorsal fin, terminal mouth, no barbel on the head, and a pair of nasal spines on the snout. It differs from Anoplagonus occidentalis Lindberg in having a nasal spine. We describe it as the first record within the Korean fish fauna, and propose the new Korean name "Ak-eo-jul-go-gi" for this species.

A single specimen (1,058 mm TL) of Pteroplatytrygon violacea, belonging to the family Dasyatidae, was firstly collected by using drift gill net in the north-western coastal waters of Jejudo Island, Korea on 6 July, 2017. This species was characterized by having a broadly rounded snout, five pairs of gill openings, tail with a large spine, ventral tail fold not reaching to the tip of tail, no dorsal fold, and ventral surface of disc dark purple. Based on such morphological characters, the specimen was identified as P. violacea and confirmed with the nucleotide sequence of the mitochondrial cytochrome c oxidase subunit I gene. We added P. violacea to the Korean fish fauna and propose the new Korean names, "Bo-ra-saek-ga-o-ri-sok" and "Bo-ra-saek-ga-o-ri" for the genus and species, respectively.

A single specimen (373.2 mm SL) of the snailfish Careproctus colletti was collected by gill-net at Donghae-si, East Sea, Korea. This species is characterized by having the slender and stick-like teeth, lower end of gill opening not reaching to upper origin of pectoral fin, rays of lower part of pectoral fin long, reaching behind anus and margins of dorsal and anal fin dark. We described it as the first record to Korean fish fauna, and proposed the new Korean name "Meok-bun-hong-kkom-chi" for this species.

Metacercariae of the genus Stictodora encysted in the head tissue of Acanthogobius navimanus (the gobies) caught at Sachun-gun, Kyongnam Province, were identified to be Stictodora Zari Yamaguti, 1939 (Trematoda: Heterophyidae), a new parasite fauna in Korea. The metacercariae were 0.39∼,0.43 mm by 0.32∼0.35 mm in size, long elliptical, and with a thin and transparent cyst wall. Total 200 metacercariae were collected from 50 gobies. In order to obtain adult worms two kittens and a Puppy were infected each with 34∼100 metacercariae, and total 33 adults were recovered between the day 4 and day 8 post-infection. The S. sari adults measured 0.95∼1.18 mm long and 0.26∼0.32 mm wide and the eggs in uteri 0.028∼0.033 mm by 0.017∼0.020 mm. The most characteristic morphological feature of these flukes was the presence of a gonotyl and gonotyl spines arranged in two groups; densely crowded group of 30~40 spines and linearly-arranged one of 30∼40 spines, together of which made a comma(or reversed comma) shape along the lateral margin of the gonotyl. It has been proved by this study that 5. sari is distributed in southern coasts of Korea.

According to the character states of nostrils in the Barbatula species comprising 1,366 specimens collected from the major river system in Korea, distribution pattern of the two Korean Barbatula species was reviewed. The taxonomic character related to nostrils in Barbatula was very stable and two character states (widely separated and closely set) were observed in the present materials. B. toni (Dybowski, 1869) with widely separated nostrils distributes in the streams flowing into the East Sea north of Sokcho, Gangwon-do Province; Eogokcheon Stream, a tributary of Namhangang River; and Anseongcheon Stream, Gyeonggi-do Province, whereas B. nuda (Bleeker, 1864) with closely set occurs in most rivers flowing into the Yellow Sea including Nakdonggang River as well as in the Yangyangnamdaecheon Stream, Gangwon-do Province south to Bangyulcheon Stream, Gyeongbukdo Province, flowing into the East Sea as previously reported with some exception. Especially, both Barbatula species were co-occurred in the Yeongokcheon Stream, Gangwon-do Province and Eogokcheon Stream. The present results will provide a useful guide to study the regional fish fauna or fish community analysis as well as to clarify the taxonomical status of the Korean Barbatula species.

Labrid fishes, Cheilio inermis and Labroides dimidiatus were collected around Cheju Island, between April-August, 1993, and described herewith as new to the Korean fish fauna. Labroides dimidiatus was originally described as Cossyphus dimidiatus by Cuvier and Valenciennes(1839), then reclassified as genus Labroides by Randall(1958). Underwater observations of Labroides dimidiatus have revealed the unusual food habit of removing ectoparasites from other fishes. Cheilio inermis was originally described by Forssk${\aa}$l(1775). It is distinguished from the other labrid fishes by the continuous lateral lines and elongated body form.
