Type material.

Syntypes, 26 specimens, NHM 1952:5:7:13.

Type locality.

Plymouth Sound, United Kingdom.

Depth range.

Atlantic Ocean: 3.7-323 m ( Laverack and Blackler 1974, Enequist 1949). Mediterranean Sea: 2500 m ( Chevreux 1935).

Distribution.

In the literature, this species name has been widely recorded from the north-east Atlantic Ocean, with a single record from the Mediterranean Sea.

North Atlantic Ocean. Denmark: the Skagerrak and the Kattegat ( Meinert 1890). France: South-west of Belle Île ( Chevreux 1898). Iceland: South-west coast ( Stephensen 1923a). Ireland: Bantry Bay ( Haddon 1886); off Fastnet Rock ( Pocock 1889); off Galley Head ( Walker 1895). North Sea Area: north-west North Sea ( Raitt 1937). Norway: Søndfjord; Hardangerfjord; and Haugesund ( Boeck 1871, 1872); Alesund; Kristiansund ( Boeck 1872); Trondheimsfjord ( G.O. Sars 1890, Oldevig 1959); Skjerstadfjorden; Herdafjord, Bergen ( Nordgaard 1911); Lofotens ( Stephensen 1932); the Skagerrak ( Enequist 1949); Raunefjorden ( Mattson 1981). United Kingdom: Plymouth Sound ( Bate 1862); Banff ( Bate 1862); Macduff ( Bate 1862); Moray Firth ( Bate and Westwood 1863); Shetland Islands ( Norman 1869); St. Andrews (from the stomach of a haddock) ( M’Intosh 1874, Laverack and Blackler 1974); Loch Fyne ( Robertson 1888, Chumley 1918); Loch Goil ( Robertson 1888, Chumley 1918); off Garnock Beacon ( Robertson 1888); Kilchattan Bay ( Robertson 1888); Cumbrae ( Robertson 1892); West of Bradda Head, Isle of Man ( Walker 1895, 1896); Firth of Forth ( Scott 1898); off Aberdeen ( Scott 1900); Gareloch ( Chumley 1918); Dunoon Basin ( Chumley 1918); Skate Island ( Chumley 1918); off Dartmouth, Devon ( Chevreux 1935); Clyde ( Sanderson 1973).

Mediterranean Sea. France: Off Corsica ( Chevreux 1935).

Ecology.

A scavenger that has been collected in baited traps ( Chevreux 1935) and from dead fish on fishermen’s lines ( Sars 1890).

Discussion.

We follow Stebbing (1906) and consider Tryphosa serra Meinert, 1890 to be a possible junior subjective synonym of Scopelocheirus crenatus . The record of Chevreux (1935) from off Corsica is the only known record of this species from the Mediterranean and is an order of magnitude deeper than all the Atlantic records. It may be a misidentification of Scopelocheirus polymedus Bellan-Santini, 1984.
