This is the first report of Japonolaeops dentatus Amaoka, belonging to the family Bothidae, collected in Korea. Four specimens (152.9~174.7 mm in standard length) were caught in the coastal waters of Jeju Island by using the bottom trawl. This species was characterized by the following morphological traits: 115~120 dorsal fin rays, 96~98 anal fin rays, 105~106 pores in lateral line, upper jaw extending to below anterior margin of lower eye, and teeth presenting on both ocular and blind sides of the jaw. We propose a new Korean name, "Geom-eun-kko-ri-neop-chi-sok" and "Geom-eun-kko-ri-neop-chi" for the genus and species, respectively.

A bothid specimen (65.8 mm SL) collected from southern coastal waters of Tongyeong, Gyeongsangnam-do, is identified as Engyprosopon grandisquama. The specimen represents a new Korean record for the species. It is characterized by the presence of 6 gill rakers on the lower limb of the first arch, caudal fin with a pair of large jet-black blotches between the 3rd and 4th rays counted from the upper and lower margins, and body depth more than 50% of body length. A new Korean name "keun-bi-neul-neop-chi-sok" and "keun-bi-neul-neop-chi" is proposed for the genus and species, respectively.

Morphological characteristics of the cross-bred $F_1$ hybrid between female Paralichthys olivaceus and male Platichthys stellatus were studied. The hybrids showed common biological characteristics of both parents, but showed more morphological similarity to P. stellatus than P. olivaceusin the following biometries: higher ratios of body length to body height (56.3%), head length to snout length (20.6%), and head length to upper jaw length (34.2%). They also showed some significant biometric characteristics similar to P. stellatus, such as ratios of predorsal length (10.5%), prepectoral length (32.2%), preventral length (29.8%), and preanal length (28.0%) to body length. The hybrids had black spots on the dark brownish-green area near the eyes, and they lacked the small bony tubercles that area characteristic of Platichthys stellatus. The hybrids had unique bands: 6~20 bands on the dorsal fin and 5~10 bands on the anal fin that gradually lost their coloration towards the fin margins. The number of fin rays were 60~66 for dorsal fin, 40~51 for anal fin, 18~21 for caudal fin, and 11~12 for pectoral fin. The gills of the hybrids contained 13~18 gill rakers and 73~98 gill filaments. The vertebrae of the hybrids numbered 34~37, with 2~3 vertebrae fused from the start of the caudal vertebrae.
