Further notes on Leptolida (Hydrozoa: Cnidaria) from Canadian Pacific Waters

This paper includes new data on Anthoathecatae and Tiarannidae. Paulinum gen. nov., Paulinum lineatum spec. nov., and Euphysa vervoorti spec. nov. are described. A single specimen was assigned tentatively to the Trichydridae as incertae sedis gen., incertae sedis spec. nov. An additional four species (Calycopsis bigelowi, Merga reesi, Paragotoea bathybia and Modeeria rotunda) are recorded from Canadian Pacific and adjacent waters for the first time. The species Bythotiara depressa Naumov, 1960 is redescribed and its relationship to other Calycopsidae is discussed. Other data are briefly summarized to update the Anthomedusae portion of Arai & Brinckmann-Voss (1980:1).
