| Summary: | The Hudson bay, a great inland sea situated well to the south of the arctic circle, has its two entrances at the northern extremity, one into the Arctic ocean and the other through Hudson strait into Davis strait. As the whole region lies within the area of the most recent glaciation, its fauna must have been re-established since the recession of the glacier from northern sources. This will probably explain the fact that practically all of the species are those of Greenland and arctic America, which in turn are chiefly circumpolar in distribution.Collections made in 1897, 1904, 1927, 1928, 1929 and 1930 of bryozoan material from the northeastern part of the bay, from Hudson strait, and from the region about Port Churchill in Manitoba, show seventy-five species and well marked varieties, including two species described as new, Bugula simpliciformis and Callopora ungavensis, with one striking variety, Gemellaria loricata var. cornuta. |
