parrii, Ophidium Ross [J. C.] 1826:109 [Zoology of the Arctic regions; ref. 18641] Baffin Bay, between western Greenland and Baffin Island and Prince Regent's Inlet, off northern Canada. Syntypes: whereabouts unknown. Originally thought to be a zoarcid; it was described from Baffin Bay. Günther (1862:325 [ref. 1969]) established the genus Uronectes [preoccupied by Uronectes Bronn, 1850 (Crustacea)]; therefore, Gill (1884:180 [ref. 1725]) suggested Lycocara as a replacement. Under that name it was considered the only generic Arctic endemic zoarcid. Unreported after its original description, Andriashev & McAllister (1978:710 [ref. 6988]) determined that it is a liparid and a senior synonym of Liparis koefoedi. In 1980 (Able & McAllister 1980:18 [ref. 6908], Able 1990:488 [ref. 20106]) synonymized it as a junior synonym of L. fabricii.
