but for the rest only a narrow friuge along the east coast of Samsø. It reaches 

 down to 5 — 5V2 fathoms depth. Tlie Zostera is fairly long and vigorous, but 

 grows scattered (mixed vegetation). 



8. Great Belt and Langeland Belt. A similar vegetation as in 

 Samsø Belt is found along the coasts of Funen and Langeland. The /ostera is 

 long and vigorous, but grows scattered and mixed with a great many algæ whieli 

 are mostly fixed to small stones, found on the bottom there. Where there are 

 bays and fjords the occurrence of the Zostera vegetation becomes broader, as between 

 Funen and Romsø, iu Kjertemiude Bay, between Funen and Langeland (Lunge 

 Bay); it is here the large vigorous Zostera with oecurs. To the south we again 

 reach the just-mentioned extensive vegetation between the small Islands south 

 of Funen. 



The Zostera reaches down to a depth of 5 — 5V2 fathoms in the open Belt, 

 and to 4 — 41/2 fathoms iu the bays. 



I am but little acquainted with the conditions on the Zealand side, but 

 what I know agrees witli those mentioned for the western side. Rich vegetation 

 is thus found e. g. in Kallundborg Fjord and Musholm Bay and in Albu Fjord. 



9. The north coast of Zealand. The open north coast of Zealand 

 does not offer favourable conditious for Zostera, and it is also but a sparse and 

 scattered vegetation we find here in the narrow coastal margin to ca. 5 fathoms 

 depth. The Zostera is fairly delicate and narrow-leaved, and generally oecurs 

 scattered among the algæ; the bottom is firm, sandy or stony. These are the 

 conditions from Refsnæs to Vrøj, round Sejerø, and from Zealand Odde to the 

 Sound; the Zostera is even at many piaces wanting altogether, especially on this 

 last extensive tract. 



Iu Nexelø Bay however we find a rich and abuudant vegetation on soft 

 bottom from 4 — 2 1/2 fathoms (see p. 24). 



10. Isse Fjord. Concerniug Holbæk Fjord reference may be made to 

 Report I of the Biological Station. The widely distributed, dense vegetation of 

 abuudant MudZostera reaches out to 2 — 2V2 fathoms dejith. Similar conditions 

 occur in the other bays of the Isse Fjord while the Isse Fjord itself is only eovered 

 on a narrow strip along the coast. 



11. The Sound. In the uorthern half of the Sound from Elsinore to 

 Drogden, good Zostera vegetation oecurs from the coast to alrøut 4*/., fathoms, at 

 many piaces, liowever, with bare spots or greatly mixed with algæ. The best 

 vegetation is in about 3 fathoms. The Zostera is long and broad-leaved at most 

 piaces, as usually less vigorous close under land and at sandy piaces, e. g. in 

 Nivaa Bay and off Rungsted. 



More to the south, in Køge Bay, the vegetation is of less importance. 



12. The Smaaland Waters. In the waters between the south coast of 

 Zealand and Lolland-Falster the most widely distributed Zostera vegetation in our 

 waters is found. It attains its most luxuriant development in the island -rich, 

 sliallow waters north of Lolland (Fæmø Sound, etc), where the large vigorous
