Remarks. When describing Scalpellum nymphocola Hoek (1883) noted that this species “comes very near to Scalpellum angustum G.O. Sars ”. Withers (1922) pointed out that S. angustum G. O. Sars, 1879 was a homonym of S. angustum Dixon, 1850, a fossil. The name S. sarsi was proposed as a replacement name by Withers (1922), but S. nymphocola is the oldest available name for this taxon.
Hoek (1883) also mentioned material from HMS “Triton”, Stn 8: Atlantic, Northeast (South of Faroe Islands), 1170 m. The material cannot be located in the NHM collection.
