The W biting (Gadus meriangus), but ouly smaller si^ecimens, never above 

 10 iuch. loug. 



The Cod {Gadus callarias), iu various sizes, but rarely the very large ones; 

 tlie fry of the year as well as the one year old lish also seem to appear 

 iu much smaller numbers than the iutermediate ages (10 — 20 iuch.). 

 Much more rarely occur: 



The green Cod (Gadus virens); most frequeutly only young specimens, but 

 never the fry of the year. Trigla gurnardus, Callionymns mamlatus, Aphya 

 pellucida, and Lahrax lupus. The latter is a very rare migratory fish, 

 whicli iu our seas has been caught only in this locality. In 1897 it was 

 caught a few times in eli weels at Frederikshavn: October the Uth, 12th, 

 and 28th. 



In autumn we often see the trout [Sahno trutta) in the rough wa- 

 thers about the stone-banks. Af ter its stay in the sea, it goes towards the 

 shores at this time to enter the water courses. 



Quite a large number of sharks are also seen now and then in this 

 locality, These proportionally large and quick fish are scarcely ever 

 caught in the seines, but most frequently on hooks or in pound-nets. 



The picked Dogfish [Acanthias vulgaris) is by far the most frequent of 

 tliem, but now and then also other forms are seen; in September 1898, 

 for iustance, two rather large specimens of Galeus vulgaris were caught 

 in pound-nets at Frederikshavn. 



As above mentioned, we meet in the zostera helt a consideralile number 

 of larger and smaller stone-banks, with a rich algæ vegetation. Be- 

 sides the natural banks, Busserev, Brunerev, etc, we may class among these 

 also the long stone moles at Frederikshavn, where the same algæ and lower 

 auimals are living: chitons, snails, bryozoa, various bydroids, etc. 



The locality, however, is too limited to develop a rich fauna, and, more 

 particularly, very few fishes may be said to be at home here. 



The otter-seines are not well calculated for the exploration of the fish- 

 i'auna ou this bottom; generally we must have recourse to weels, as the small 

 dredges, though they may be used here, are but badly adapted for the catchiug 

 of fish. 



Now and then, however, a lish which is particularly attached to the
