Ecological and systematic studies of Ecological and systematic studies of the Ceylon species of Caulerpa ecologicalsystem00unse Year: 1906 122 CEYLON MARINE BIOLOGICAL REPORTS.

This form should, on the contrary, most certainly be derived from davi- fera, the only closely related form that grows in the district and of which it must be considered as a deeper water or shade form. Naturally it could imaginably be derived from C. uvifera, but this Caulerpa does not occur at aU within the south-west region of Ceylon, but only in the north. Whether it is identical with J. G. Agahdh's C. racemosa laxa (Till. Alg. Syst. I p. 35) can only be determined by examining the type- specimens, but there are none in Agardh's Herbarium. I propose to call this form /. remota. I have not found any periodicity at all in the development of this species; it seems to have the same appearance all the year round. Geographical distribution.—^Ceylon : very common along the coast, but especially on the south- west, more rocky part with coral reefs. Tangalla! Dondra Head! Matara! Weligama! Galle (with /. remota)!
