16. Marinogammarus pirloti Sexton & Spooner , 1940

Synonyms: Chaetogammarus pirloti auct.; Echinogammarus pirloti auct.

Description and illustrations: Sexton & Spooner 1940, p. 667, figs 9-10, pl. 4; Lincoln 1979, pp 265-269, figs 122b, 124 ( Chaetogammarus p.).

Ecology and habitat: Intertidally, under stones and among algae ( Ascophyllum, Enteromorpha ) at places where freshwater flows out. Distribution very patchy, but may be numerous where occurring. Apparently confined to the outer coast.

Distribution in Norway: Not well known. Discovered in Norway by Tulkki (1963) in the outermost Hardangerfjord. Later once found in the Oslofjord (C. Christophersen, pers. comm.) and a few places between Hardanger and the outer Trondheimsford ( Vader 1969), in all cases close to the open coast, as is also the case in Britain ( Spooner 1957). Not yet found further north than the Trondheimsfjord, but may well occur there.
