lashing of tlie waves here reaches deeper down), we do not meet the charac- 

 teristic »clay animals«, e. g. Brissopsis, coustantly, till deeper down, on more 

 than 30 fathoras, while we find them in the C!attegat already on 15. The fauna 

 is very rich on 20—30 fathoms, both in fishes and in lower animals. The for- 

 mer are represented by the same species of cod-fishes and fat-fshes as are 

 found in the deeper parts of the Gattegat. Loose Laminariæ are found, at times, 

 and at certain piaces, in masses, probablj' carried hither by the current from 

 stones on the western shores of Jntland. 



These regions are especially characterized by their rich plaice-fishery, 

 which is carried on by the Danish fishing-cutters with plaice-seines. But also 

 the foreign trawlers are working here, particularly to catch liaddochs {Gadus 

 rpglefinus). cod [Gadus callarias), hal:es {llerliicins snviridiis), and the pole dah 

 [Pleuronedes cynoglossus). 



Between 40 and 60 fathoms Brissopsis lyrifera is never missing, 

 except wlien replaced by Amphidetus or Spatangns. Nr. 14, 16 — 18, 22 — 26. 

 The fishfauna, nevertheless, still agrees very closely with that of the former 

 region, but the codfishes are more dominating than the flat-fishes. The plaice 

 is missing, or is rare, and of the codfishes Gadus Pontassou, which does not 

 live in the Gattegat, has been added. Gadus EsmarJcii is common and Lycodes 

 begin to appear. 



The Danish fishing-smacks scarcely ever fish here, but the trawlers take 

 great numbers of cod, luiddoclc, the pole dah, and other fishes. 



On 70 — 80 fathoms, Nr. 10 — 13, Brissopsis is never missing. Astro- 

 pecten Andromeda is added here; it never goes into the Gattegat. A great uum- 

 ber of other invertebrates occur here, which are not found in the Gattegat. 



Of flat-fishes we find only the pole dah [Pleuronedes cynoglossus) in great 

 numbers, and moreover the long rough dah [Drepanopsetta platessoides). 2 spe- 

 cies of Lycodes are common, besides the haddocl; and other species of gadus, 

 and Ung [Moha vulgaris). A small species of codfish [Gadiculus argenteus) has 

 been found. The hag {Myxine glotinosa) occurs, evidently in great numbers, 

 but singly only in the fishingapparatus. The steam-trawlers are fishiug here 

 for haddoclc and the pole dah. ' — 



The young ones of the latter are found out here; they have never been 

 observed iu the Gattegat, and, as it is the opinion of English iuvestigators also, 

 they are at home, evidently, on deep water only. 



As aljove mentioned we find a great number of lower animals, particularly 

 echinodermata and crustacea decapodea in great masses. This fauna goes
