either pure sand bottom or stony sand-bottom, and in the last case (cominonly in 

 somewhat deeper water) we often find a vegetation of delicate algæ (Edocarpus, 

 Polysiplionia, Ehodomela etc.) and sometimes some Characeæ (Tolypclla. Chara hcil- 

 tiea). We only find the Zostera in scattered, small patches and short and narrow- 

 leaved; the conditions most nearly correspond with those of the Kattegat and the 

 north coast of Zealand, in spite of the great difference in the salinity of 

 tlie water. 



The Zostera reaches down to a depth of SVj fathoms off the east coast of 

 Falster, and to ca. 4 fathoms in Faxe Bay; but the vegetation is so sparse that 

 it is of no practical importance. There is no difference in the Zostera piants from 

 the deepest piaces and those from shallow water. 



On the open coasts of Bornholm the Zostera is not of any importance 

 to the fisheries; there are ouly here and there some small scattered patches of 

 short and narrow-leaved piants.
