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.
