Archive image from page 83 of The Danish Ingolf-Expedition (1919). The Danish Ingolf-Expedition danishingolfexpe0508ingo Year: 1919 76 I. walls are destructed and detached from the subumbrella, only the narrow entodermal stripe, along which the canal was attached to the snbumbrella, remaining. The sexual products are first evacuated in the proximal part of the gonads, so that at a certain moment the radial canals are seen attached to the subumbrella by the parts free of gonads and by the distal part of the gonadial part, from which the sexual products are not yet evacuated, while the part, in which the evacuation has been completed, hangs freely downwards like a bow (see the diagram, textfig. lo). Female individuals, which have evacu- ated the eggs, are found to measure 40—56 mm in diameter; a male specimen, 44 mm wide, has spawned. Occurrence: The occurrence of Halopsis occllatn at the coast of North America is limited to the Gulf of Maine from Grand Manan to Cape Cod (A. Agassiz, Fewkes, Bigelow). The distribution on the European side of the North Atlantic is as follows: The species is common all along the south coast of Iceland, mainly in the neighbourhood of the coast. Hitherto it has not been found at the Faeroe Islands. It is common in the waters between Scotland and Rockall, and has been found, moreover, south-west of Ireland. As mentioned above, it has not previously been recorded from the European waters, thus all our knowledge of its occurrence in that area is based on the material here dealt with. It will be observed from chart IX, that it does not at any point surpass the Wyville Thomson ridge. As it has, besides, not been found at the western or northern coasts of Iceland, its distribution may be designated as being entirely Atlantic. The occurrence seems, moreover, to be mainly neritic. Thus during the cruise of the Fig 10 Haiop,,s oceUata A, .\gassiz. Dia- 'Armauer Hansen' in 1913 the species was only found on stat. =ent°'°/exutbreut°''
