Abstract

A new species of Corvaspis, C. arctica, is described from the Peel Sound Formation of Somerset Island, North-west Territories, Canada, where it occurs in association with Hemicyclaspis murchisoni (Egerton), an index fossil for the lowest Downtonian of Britain. C. arctica sp. nov. is considered to have been a streamlined form, with an undivided dorsal shield; it is probably related to the Cyathaspididae.
