curious specieshere figured to Cladophora, on account of the decided tendencyto anastomosis among the ramuli, a tendency that increases withthe age of the plant, and in full-grown specimens (if ours be, asI suspect, immature) would probably be more strongly indicated.The anastomosing ramuli show an affinity with Microdictyon,and consequently with the ValoniacecB; but the character is notso decided as in Microdictyon, and the nature and ramification ofthe filaments are very similar in this plant to what they are inCladophora composita, and several other undoubted species ofthat genus. On the whole, therefore, I prefer leaving C. anasto-mosans in Cladophora until some better place be found for it. It is a deep-water plant, and as yet very rare. The only spe-cimens seen were picked up after a gale, on the shore, near SwanRiver. It has not yet been sent by Mr. Clifton ; another proofof its rarity. Fig. 1.
