Microstomum jenseni Riedel, 1932

Microstomum tortipenis Steinböck, 1938: 7 , Figure 4 a–c.

Material examined

Site 15: two specimens, in squash preparation.

Geographical distribution. NW Atlantic: Davis Strait ( Greenland: Disko Bay); NE Atlantic: Iceland (Isafjördur); North Sea: North Frisian Islands (Sylt), Norway (Herdla off Bergen); Skagerrak: Gullmarfjord (v. Graff 1913; Steinböck 1933a, 1938; Westblad 1953; Faubel 1974b, 1976 a, 1977).

Remarks

The specimens collected, like the population of the Island of Sylt, did not possess rhabdites. Riedel (1932) and Westblad (1953), however, discerned rhabdites in their material collected from Disko Bay and Gullmarfjord, respectively (cf. Faubel 1974b).
