24 Rev. A. F. Kemp on the Shore Zones of 



adhering to the rocks, clumps of Cladophora rupestris, C.uncialis^ 

 and C. Jiexuosa were found. Masses of the bright green and gelat- 

 inous Hormotrichum Younganum were also found adhering to the 

 edges of the rocks. These plants have a considerable range of 

 growth and some of the Cladophorse may be found in fine condi- 

 tion as far down as the lower limits of the third zone, but there 

 . they assume a deeper green color and stronger texture. Entangled 

 among other plants, the dark green crisp and tortuous Ghcetomor' 

 pha litorea finds also a home. This plant has however a consi- 

 derable range of growth, and is not specially abundant in any 

 place only it does not grow in very deep water or far down on 

 the shore. Of the £Jnte7'omorpha it may be remarked that it is 

 very troublesome to the fishermen, as it infests the bottoms of the 

 boats, and greatly retards their progress in sailing. It adheres to 

 them with great tenacity, and in an incredible short space of time, 

 covers them with a perfect foi-est of long green fronds. The 

 only remedy for this pest is frequent scraping, burning and tar- 

 ring. 



In this second zone there are found, besides, stragglers from the 

 zone beneath. 



The chief and most notable of these is a dwarf species of 

 Facus. It grows in the corners aud crevices of the water pools, 

 and travels very little beyond the Ulva Zone. In its dry state it 

 has much the appearance of a Bictyota, but in its fresh condition 

 it is thick and feathery as a Facus. It may be a dwarf form of 

 Fucus vesiculosus^ but in no case did I either find air vessels or 

 terminal receptacles upon it. It had always the same appearance : 

 a plain narrow frond with a slender midrib frequently bifurcating 

 in a dichotomus manner. Its colour is a pale olive. Hervey 

 does not notice this plant in his Nereis Borealis but in his Manual 

 he describes a plant of the same kind as a variety of Fucus vesicu- 

 losus under the name of F. Balticus, stating at the same time 

 that it is probably a depauperised condition of F vesiculosus. It 

 may be so, but I was not able to trace the connection between the 

 two by intermediate forms. I am disposed to think that it is enti- 

 tled to a specific name, and that it may retain that of F. Balticus, 

 Dwarf specimens of Fucus nodosus are also found creeping up 

 into this zone, but regarding these no doubt can be entertained. 

 Their linear form and occasionally inflated fronds sufiiciently 

 indicate their connection and origin. The rocks are also covered 

 with a soft velvety green substance apparently made up of a
