 about the islands, and dredged down to 18 m.; in quiet places as large, 

 thin fronds, in exposed places masses of short, irregular, densely 

 packed fronds. Apparently equally common at all times of the year. 

 Aug. 11, 1913, in the cave at Agar's Island, yoimg plants were found 

 growing on the rocks between tides, forming a continuous coating, 

 the individual plants not over 1 mm. high. In some individuals the 

 lamina was beginning to form, but most of the plants resembled young 

 Cladophora, except that the branching was in one plane. There was 

 a distinct filiform stipe, attached at the base by slender- coralloid 

 projections.
