Ixxxiii rather longer than the preceding; second pair of legs slender, very short, bristled, andunarmed, in which last essential point it differs from the Poritophilus spitiosus of , Mai. Pod. Brit., t. 37, to which in other respects this species bears a nearresemblance. It is more rarely met with in the Arctic Seas than the Crangon Boreas, but a fewspecimens were obtained near Felix Harbour.
