Abstract
The anisakid nematode originally called Ascaris decipiens Krabbe, 1878, the adults of which occur in seals in the Atlantic off the eastern coast of Canada, is removed from the genera Porrocaecum and Terranova in which it has been variously placed and is made the type and only species of the new genus Phocanema. The hosts of the genus Porrocaecum are birds and the hosts of the genus Terranova are elasmobranchs.
