Monotis typica (Kipar.), M. cf. M. haueri Kittl, and M. cf. M. daonellaeformis Kipar. are for the first time described from Canada. M. typica occurs in the Pardonet formation of British Columbia, doubtfully in the Lower Norian, and probably throughout the Middle Norian. Associated with the upper Middle Norian Himavatites columbianus ammonoid assemblage of the same area is M. obtusicostata sp. nov.; it occurs with the first usually sparse M. pinensis West. and the last Halobia.M. pinensis usually flourishes just above this assemblage. Monotis cf. M. haueri occurs in the Upper Norian 'formation D' of the Lewes River group in southern Yukon. M. cf. M. daonellaeformis is described from the Middle Norian of Axel Heiberg Island in the Arctic. The Monotis sequences of British Columbia and Japan compare closely, while the Canadian and Siberian Arctic faunas show great similarity.
