The group isextremely interesting, as exhibiting progressive and retro-gressive development, and deserves more attention than itappears to have hitherto received. The female (fig. 6) isabout I-18th inch in length, the male rather smaller, andthe larval form (fig. 1) about half the size of the female.I am indebted to our colleague Mr. Helenus Robertsonfor kindly producing enlarged micro-photographs of this 64 LIVERPOOL BIOLOGICAL SOCIETY. and other species from my momited specimens, thus greatlyfacihtating the task of subsequently drawing them.

Since the last Eeport on the Marine Copepoda of thedistrict, thirty-one additional species have been recorded,making fifty species altogether known to the district.Four of them are new to Britain, three of them beingaltogether new to science. Two of the other species havenot been before recorded in Britain for fifty and thirtyyears respectively. Some of the species noticed in the first Eeport as havingbeen found locally or sparingly have since proved to bevery common throughout the district. Of these may bementioned Pseudocalcnms elcngahis, Bias longiremis andOitho7ia spinifrons.
