It varies in length and breadth; sometimes short and narrow, at other times two feet long and three inches in diameter. It is always simple, whereas E. compressa is branched. It changes from pale-green to yellow, and be- comes white in decay. The most interesting specimens I ever got of this plant might be regarded as subfossil. They were found in a sand- stone quarry at Ardeer, Ayrshire, about a mile from the sea. When the quarriers had removed about six feet of earth, they came to a thick stratum of shale, which was perforated in many places, and in the mouth of the bore, which was about an inch in diameter, I generally found a pretty entire specimen of Ekolas crispala, the very same kind of mollusk that I had often seen boring the shale in the sea at Salt- coats. The perforation was about six inches deep, and at the bottom of the bore there was in all cases a matted pellet of vegetable substance. On macerating this, it spread, and I saw by its puckerings and reticulations that it was Enteromorpha inlesllnalis. 1 sent it to Sir William Hooker, and he said that it was correctly named.
