Phycologia britannica, or, A History of British sea-weeds, containing coloured figures, generic and specific characters, synonymes, and descriptions of all the species of algae inhabiting the shores of the British Islands . er of loner joints, which is the strongest of those mentioned, is not to bealtogether counted on; for though I have not observed the jointsin any specimen of C. rupestris to be of the extreme length ofthose of C. nuda, yet I have seen a tendency in some specimensof that species to produce long joints ; and this, joined to thenon-occurrence in recent times of C. nuda, has latterly disposedme to consider it a variety of C. rupestris. As, however, it hasalready obtained publicity both in this country and on the Con-tinent, I think it deserving of being figured in this work, andshall be happy to find that future researches prove its title to re-ceive a name. Last summer (1850) I sought for it diligently onthe basaltic rocks in the neighbourhood of the Giants Cause-way, but in vain; and it was out of my power to extend the ex-ploration as far as Port Stewart.
