Pleurobrachia pileus (O. F. Muller).

This species has been recorded from New Zealand waters by Moser (1909) and Ralph (1949) and the present study only places on record that the New page 2 Zealand specimens of P. pileus are efficient fish catchers. On several occasions larval fish observed when the net was taken on board were missing when the haul was later examined. Once P. pileus was seen to come in contact with a larval fish as large as itself. The fish seemed to die immediately and in approximately an hour was within the stomodeum. The economic importance of this habit has been emphasized elsewhere. (Bigelow, 1924.)
