various species of Ceranium and Polysiphonia 

 are very abundant, as are also the species 

 of Monodroma, Ulva, Enteromorplm and Clado- 

 phora. 



In the ponds at the upper end of the 

 valley occupied by the harbor, fresh-water 

 algffi are present in great abundance and 

 variety. Besides several unusual species 

 of Schizophyceffi, such genera as Pandorina, 

 Volvox, Oedogonium and Bulbochcete are oi 

 frequent occurrence. In the springs and 

 pools on the edges of these ponds an un- 

 usually large number of genera of desmids 

 are present and Batraehosjjermum is occasion- 

 ally found. Many interesting hydrophile 

 phanerogams are also present in these 

 ponds. 



It is in the dense woods surrounding 

 these ponds that we find the most interest- 

 ing feature of the whole region. These 

 woods are chiefly of oak, chestnut, beech 

 and birch, with an undergrowth of Clethra 

 and Hamamelis in the damper portions and 

 of Kahnia in the drier ones. The damp soil 

 and air make exceptionally favorable con- 

 ditions for parasites and saprophytes. 

 Such forms as Cuscuta, Monatropa and Coral- 

 lorhiza are abundant, while the variety and 

 abundance of the Myxomycetes and Fungi 

 are quite remarkable. Fifteen genera of 

 Myxomycetes, six of them new to the 

 island, have already been noted and many 

 new species of the more common genera 

 will probably be found when the study of 

 the region can be carried beyond the limited 

 territory already visited. Among the Fungi 

 the Pyrenomycetes, Hysteriacese, Dis- 

 comycetes and Helvellacese of the Ascomy- 

 cetes, and the Hymenomycetes, Phalloidese 

 and Gasteromycetes of the Basidiomycetes,
