Six forms (5 of which are new) of echinactinomyxon and 5 new forms of the collective groups neoactinomyxum, aurantiactinomyxon, guyenotia, synactinomyxon, and antonactinomyxon of oligochaetes in Lake Sasajewun, Algonquin Park are described. Five forms of echinactinomyxon designated as echinactinomyxon 'A,' 'B,' 'C,' 'D,' and 'E,' a form of neoactinomyxum, and a form of aurantiactinomyxon were found in Limnodrilus hoffmeisteri. Echinactinomyxon radiatum, a form of synactinomyxon, and a form of antonactinomyxon were recorded from Tubifex tubifex. A form of guyenotia was found in Lumbriculus variegatus. The sporoplasmic mass of these actinosporeans was released through the anterior end of the epispore. An increase in the number of germ cells was observed in the floating spore stage of all forms except echinactinomyxon 'C' and the form of antonactinomyxon.
描述了在阿尔冈昆公园萨萨朱温湖寡毛纲动物中发现的6种棘肌孢子虫（其中5种为新种）以及新肌孢子虫、橙肌孢子虫、居耶诺孢子虫、合肌孢子虫和反肌孢子虫这5个群体的新形态。在霍氏水丝蚓中发现了被命名为棘肌孢子虫“A”、“B”、“C”、“D”和“E”的5种棘肌孢子虫形态、1种新肌孢子虫形态和1种橙肌孢子虫形态。从颤蚓中记录到辐射棘肌孢子虫、1种合肌孢子虫形态和1种反肌孢子虫形态。在杂色仙女虫中发现了1种居耶诺孢子虫形态。这些放射孢子虫的孢子质团通过孢子外壁的前端释放。除了棘肌孢子虫“C”和反肌孢子虫形态外，在所有形态的游动孢子阶段均观察到生殖细胞数量增加。
