The life cycles of Lembos websleri Bate and Corophium bonnellii Milne Edwards are based on two generations per year. Eight cohorts have been identified in Lembos and nine for Corophium, each of which has a different longevity. In Lembos the summer generation

Lembos websteri Bate and Corophium bonnellii Milne Edwards are tubicolous. The morphology of tubes collected from Laminaria holdfasts is described and contrasted with that of tubes built amongst filamentous algae in a wave-sheltered environment. In
