Daucus species vegetated in the island Dae-heug-san-do off the Korean Peninsula has been recorded as Daucus littoralis Sibth. et Sm. var. koreana Nakai, endemic to Korea in several flora. However, the name was revealed as a naked name, nomen nudum, because the valid publication and type specimens were found anywhere. Comparative observation on morphological characters between the Korean taxon of Daucus and D. littoralis reveals that the Korean vegetated in the island Dae-heug-san-do is not the D. littoralis, but the D. carota L. subsp. carota. The Korean name of the latter is designated newly as San-dang-geun. The new korean name, Seon-dang-geun, of the unrecorded taxon, D. carota subsp. maritimus (Lam.) Batt., is also given.

In this study, we intended to describe an unrecorded species of heterophyid trematode recovered from the small intestine of a Korean raccoon dog, Nyctereutes procyonoides koreensis, in Korea. A total of 13 small flukes were collected from a deceased Korean raccoon dog which was found in Chuncheon-si, Gangwon-do, Korea in May 2017. The trematode body were covered with many small spines, rectangular, broader than long, 807-1,103 ㎛ long and 1,270-1,550 ㎛ wide. Oral sucker in the anterior end slightly smaller than acetabulum. Pharynx muscular and well developed. Esophagus relatively long and sigmoid. Acetabulum small and located at median in anterior 2/5 portion. Ceca bifurcated at the anterior of genital pore and acetabulum and terminated at testis level. Testes larger, deeply lobed and located at the near of posterior end of body. Ovary small, triangular and located at the slight left of median and the anterior of left testis. Vitelline follicles dendritic and extend from the middle level of esophagus to the posterior portion of body. Eggs embryonated, operculated, small and 33-35×15-16 ㎛ in size. Based on the morphological characteristics, the small heterophyid flukes recovered from the small intestines of Korean raccoon dog, N. procyonoides koreensis, were identified as Euryhelmis squamula (Digenea: Heterophyidae). Accordingly, this species of heterophyid flukes is to be a new trematode fauna in Korea by this study.

Arcuospathidium is a haptorian ciliate genus composed of 18 species, and only one species has been reported in Korea. Here, we identify two unrecorded Arcuospathidium subspecies by morphological observation of both living and protargol-impregnated specimens with the small subunit ribosomal RNA (18S rRNA) gene sequence. These subspecies, Arcuospathidium cultriforme cultriforme (Penard, 1922) Foissner, 1984 and A. cultriforme scalpriforme (Kahl, 1930) Foissner, 2003, were isolated from various terrestrial habitats in July and August 2013, respectivley. Arcuospathidium cultriforme cultriforme is similar to A. cultriforme scalpriforme by a knife-shaped body, a twisted-shaped macronucleus, number of dorsal brushes, position of dorsal brushes, and shape of macronucleus but former mainly differs from the body length to oral bulge length ratio (27-38% vs. 41-53%), extrusome (one types vs. three types), cyst shape (roughly faceted wall vs. smooth surface and thin wall) and number of somatic kinety rows(18-30 vs. 30-44). Additionally, we analyzed the 18S rRNA gene sequences of two A. cultriforme subspecies and compared them with the sequences from GenBank to confirm their identification at the molecular level. As the results of genetic analysis, the 18S rRNA gene sequence of the Korean A. cultriforme cultriforme population is most similar to that of Austrian population. Also, the sequence of the Korean A. cultriforme scalpriforme population is most similar to that of another population with some nucleotide differences.

In May 2020, a single larval specimen (5.14 mm in total length) was collected from the southeastern sea of Jeju Island of Korea using bongo net. The specimen was identified as Lepidotrigla longifaciata based on mitochondrial DNA cytochrome c oxidase subunit I sequences. The morphological traits of the L. longifaciata larva are as follows: a long snout, a large mouth, large fan-shaped pectoral fins, and black melanophores scattered on the abdominal cavity and nape. We propose the new Korean name 'Gin-meo-ri-dal-jae' for this species, which was first discovered in Korea.

Larvae of fishes were collected at 26 stations in the Korea Strait, by horizontal towings using the fish larval net (Norpac) in the surface layer and by oblique towings using Isaac-Kid mid-water trawl in the mid-water layer in summer (July) and in autumn (November), in 1983. The towing speed was 1.5 knots. Of the larval fish examined, 3,529 individuals were identified to generic and specific levels. They belong to 27 families, consisting of 38 species in 37 genera. Unidentified were 114 specimens. The most abundant species was Engraulis japonica which occupied $88.5\%$ of the whole 3,645 individuals. Diaphus sp. took the second place with 50 individuals ($l.3\%$). Seasonally abundant species were in the order of Engraulis japonica, a Gobid, Trichiurus lepturus, and Diaphus sp. in summer, and in the order of Diaphus sp., Engraxlis japonica, Bothus sp., and a Ophichthid in autumn. Of these larvae, Engraulis japonica and Diaphus sp. continuously appeared from summer to Autumn. Champsodon sp., Diaphus sp. and Synagrops philippinensis were unrecorded species in Korea.

Two unrecorded naturalized species, Lolium rigidum Gaudin (Poaceae) and Oenothera rosea L'H$\acute{e}$r. ex Aiton (Onagraceae) were newly reported in Korea. L. rigidum, 'Daeng-Dol-Bo-Ri', was found at roadside of Yesong beach, Yesong-ri, Bogil-myeon, and roadside of Myeongsasimni beach, Sin-ri, Sinji-myeon, in Wando-gun, Jeollanam-do. It was distinguished from L. mutiflorum Lam by spikelet 10-20 mm long, florets 2-10(-13), and obtuse lemma, awn absent or up to 3-8(-10) mm. O. rosea, 'Ae-Ki-Bun-Hong-Nat-Dal-Mat-I-Kkot', was found in side of Wondong wetland, Yongdang-ri, Wondong-myeon, Yangsan-si, Gyeongsangnam-do. This taxon was distinguishable from other Oenothera in Korea by following combination of characters, stem erect to ascending, petal 5-12 mm long, pink to bright purple. Descriptions and illustrations of the two taxa and their photographs in the habitat are provided along with a key to the species of Lolium and Oenothera from Korea.

Since a new (unrecorded) species was reported in 2016, a total of four sea snake species are currently listed in Korean waters. Although the possibility of year-round inhabitation of sea snakes in Korean waters has increased due to climate change, the related studies are scarce because of the lack of human resources and available equipment. We placed posters and banners requesting voluntary information on sea snakes in coastal regions and Jeju Island to obtain information on sea snake distributions in the coasts of South Korea and possible specimens through volunteer activities. As a result, we received total 45 reliable reports, including photographs or video, between March 2013 and December 2016. Eighteen reports on three sea snake species and thirteen capture cases of two species were submitted from Jeju Island and southern coastal regions of Korea mostly between August and November. There were twenty-seven false reports including seven cases of terrestrial snakes, eighteen fishes, and one each of invertebrate and inanimate material. Based on the results, we proposed the effective way of sea snake surveys using volunteers.
