The Rock-pools of Bimdoran. 3 



eq7ii?ia, lyinn., of the varieties hepatica, rubra, olivacea, and 

 viridis was present everywhere. Under one of the ledges of 

 rock I met w ith a large group, thirty or forty individuals, of 

 the prett)' little Corynactis viridis, Allni. This anemone varies 

 much in colour, although those belonging to the same colony 

 are generally alike. In the present case the column was of a 

 light brown colour, the margin a rich bright orange, and the 

 tentacles green at the base, with greenish-brown stems and 

 white knobs. At Roundstonel have met with colonies of the 

 more typical green form. Specimens of Hcliactis bellis, E. 

 and S. were present in the cavities of the rock-pools, and also 

 the large Tealia crassicor^iis. Mull, in considerable variety 

 of colour. A single example of Cylista imdata, MltU. was 

 also obtained. 



The coast to the north of Bundoran is varied by steep 

 precipices and sandy shores. Around Claddaghlagan not 

 much was obtained, nor along the beach in front of the east 

 portion of the towm. Rog>^ Bay, a narrow inlet, was the best 

 locality for material washed up from the sea. Here were 

 obtained stems of Laminaria with quite thick forests of 

 Sertularia operailata, lyinn., growing on them, presenting 

 almost the appearance of a fox's tail. The roots of the 

 Laminaria also yielded several species of encrusting Polj'zoa. 

 I may here record one fact in which I have alwaj^s found the 

 west coast of Ireland to differ from the east coast, namely, in 

 the amount of material from considerable depths washed 

 ashore by storms. On such occasions we find suitable places 

 on the east coast literally strewn with zoophytes and other 

 treasures from the deep. Tangled masses are rolled about on 

 the sand}^ shores, composed largely of Hydrallmania falcata, 

 lyinn., Sertularia abietina, lyinn., Eudcndrium ramosum, Linn., 

 various species of /'///^/r^ and Ciisiaf Vesicularia spinosa, Linn., 

 and heaps of other smaller forms along with them or growing 

 upon them, the whole forming a very rich and easily obtained 

 harvest. On the west coast, however, I have never found any 

 of the species mentioned above washed ashore. It has often 

 been disappointing upon going to some strand, where, under 

 similar conditions along the east coa.st, I should have obtained 

 in a few minutes thirty or forty different species of zoophytes, 

 to find practically nothing. Tullan Strand, extending a dis- 

 tance of nearly two miles from the Fairy Bridge to the mouth
