A glance at the locality named sufficed to show that the prospects of sport were not encouraging. A stiff breeze blowing towards the shore tumbled the sea too much to allow of the tow-net being put down. A move was therefore proposed to quieter waters, which were found near the Gem pier. Here a boat was secured, and, once clear of the shipping near, the tow net was put out by Mr. Shephard. The muddy appearance of the water gave little hope of success, and only a few \" dips\" were indulged in, so as to allow each member to carry home some of the spoils. However, a slight investigation of the material at home revealed a good many interesting larval forms, principally of the Echinodermata. Medusoids were also fairly plentiful, together with a Radiolarian, occurring singly and in groups.","number":null,"lower":null,"upper":null,"comparator":"=","unit":null},"caveats":{"kind":"source_reported","kind_label":"Reported by source","origin":"community_reported","origin_label":"Reported by community","period":{"text":"1895","start":"1895-01-01","end":"1895-12-31"},"verification":{"level":"reviewed","label":"Reviewed","step":3,"of":4,"meaning":"PLOT checked the claim against its source.
