Hemilepidotus hemilepidotus (Tilesius, 1811) .

Red Irish Lord. To 50.8 cm (20 in) TL (Miller and Lea 1972). Commander–Aleutian Chain, and south-eastern Bering Sea (Mecklenburg et al. 2002) to Mussel Point, Monterey Bay, central California (Bolin 1944, Peden 1978). Benthic; depth: intertidal to 235 m (771 ft) (min.: Peden 1978; max.: Pucunski et al. 2013). A Diablo Cove, central California, observation (Burge and Schultz 1973) predates the revision of this group by Peden (1978) and cannot be confirmed. Contrary to previous reports, has not been documented from the Pacific Ocean off south-eastern Kamchatka or the western Bering Sea except off the Commander Islands (Tokranov et al. 2003).
