In the course of a study of the age and growth of the Common Dragonet, Callionymus lyra L., a number of specimens of another species of Callionymus have been collected off Plymouth, differing from both C. lyra L. and C. maculatus Rafinesque, the only two dragonets previously recorded from the Plymouth area (Mar. Biol. Assoc., 1931), and, indeed, from northern European seas (Andersson, 1942; Day, 1880–84; Duncker, Ehrenbaum, Kyle, Mohr & Schnakenbeck, 1929; Jenkins, 1925; Mohr (in Joubin, 1929–38); Le Danois, 1913; Norman, 1935; Otterstrøm, 1912; Poll, 1947; Redeke, 1941; Sænundsson, 1949; Smitt, 1892–95).
