Abstract
In a previous paper (Harris, 1972) the meiofauna of an exposed sand beach at Whitsand Bay, Cornwall, was described in relation to the physical environment. During this study special emphasis was placed on the harpacticoid copepods, of which 13 species were recorded on the beach. In the present paper the horizontal and vertical zonation of the copepod species on the beach is described. An account of seasonal changes in the copepod population will be given in a subsequent paper.
