| Summary: | Sixteen species of athecate hydroids were identified in collections from the shelf waters of northern Canada between the Strait of Belle Isle and the Alaska–Yukon border. This brings the number of athecate species reported from Canada's north coast to 21, and the total number of hydroid species known from the region to 92. One species, Eudendrium caricum Jäderholm 1908 is placed in synonymy with Eudendrium arbusculum Wright 1859. No high-arctic forms were represented, and only eight of the species are panarctic or low-arctic in distribution. Of the remaining species, six occur in boreal as well as subarctic waters, and two have a wide latitudinal range. Five species, Corymorpha groenlandica, Tubularia regalis, Monocoryne gigantea, Rhizogeton nudus, and Hydractinia monocarpa, are recorded in North American waters for the first time. These five, plus Myriothela phrygia, Eudendrium capillare, and the hydroid of Euphysa, are new records for northern Canada. |
