3. The Secretary exhibited and made remarks upon an arrow-worm (Spadella), from New Zealand waters. The pela-gic group of worms, Chætognatha, comprising the two genera Sagitta and Spadella, is widely distributed, but hitherto does not seem to have been recorded in the Transactions as from the seas about New Zealand. The specimens referred to were taken in the tow-net off Antipodes Island, and in the planktonnet in Paterson's Inlet, Stewart Island, and in Norman's Inlet, Auckland Islands. They are closely allied to if not identical with Spadella hamata, Möbius.
