Desmarestia ligulata herbacea, Xitophyllum latissimum, CaUopyllis fabel- 

 lulata, and others, are found on the holdfasts of these Nereocystis plants. 



2. Along the exposed rocky shore of the southwest side of Point 

 George, Bangia atropurpurea fuscopurpurea and Porphyra perforata are 

 very abundant in the middle and upper littoral zone. 



3. On the southwest headland of Squaw Bay are several small coves 

 Avith gravelly beaches wliere Hormiscia tetraciliata is very common on 

 large pebbles near the low tide line. 



4. About 100 meters back from point 3 on Squaw Bay, on a steep 

 shad}' rocky slope. Ptilota pectiimta, Microcladia borealis, Soranthera 

 ulvoidea, Leathesia dijformis and several species of Odonthalia were 

 found very common in the littoral zone. 



5. XorthM'est of Hankin Point on the almost vertical rocks Colpo- 

 menia sinuosa, Coilodesme bulligera and Scytosiphon lomentarius were 

 frequently found in the lower littoral zone during extremely low tides. 

 Large specimens of Rhodomela larh' were found here forming rather 

 dense mats in the middle littoral zone. 



6. In a little cove east of Blind Bay (plate 34) Agardhiella tenera 

 and Polysiphonia urceolata were found very abundant on shells and peb- 

 bles scattered over the sandy bottom at a depth of 1 to 2 meters. 



7. Broken Point is a steep rocky point projecting into the channel 

 en the north side of Shaw Island (plate 35). Right on the point there is 

 very little littoral vegetation and the kelp beds are very near the shore 

 because the sides of the cliff are very steep. From just above the low- 

 tide line to about 2 meters below it there is a very dense growth of Iridaea 

 laminarioides, I.amiiutria bidlata, Alaria tenuifolia, Costaria costata, Coral- 

 Una officinalis, Amphiroa tuberculosa and species of Desmarestia. On 

 the overhanging and vertical rocks Codium mucronatum and Codium di- 

 morpliuvi were found in great masses. 



8. On this rock shore (plate 34) both species of Codium were found 

 very common. In some spots Codium covered the rocks in the extreme 

 lower littoral zone almost to the total exclusion of the other algae. 

 Porphyra nereocystis, Antithamnion floccosum and Ectocarpus confer- 

 voides were often found growing on old kelp plants near this shore. 



9. On these low overhanging rocks Apoglossum decipiens, Griffithsia 

 tasmanica (?) and Codium dimorphum were often found at or just below 

 the extreme low-water mark. 



10. A small narrow cave was found just above the low-water mark 

 on a limestone cliff on the north side of Cliff Island. The vertical rocks 

 near the entrance to this cave were covered with dense mats of Ectocarpus
