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. Finally the name was ruled invalid and placed on the Official Index of Rejected and Invalid Names in Zoology, Number 1099 (Opinion 1217). •Not available, see discussion in Chernova et al. 2004:63 [ref. 27592].
