Part II: 



The Skager Eack. 



To set up various belts (regions) with different faunas is not by far 

 so easy in the Skager Rack as in the Cattegat, partly because the Skager Rack 

 bas not as yet been so fully explored, partly because there do not exist so sbarply 

 distiuguisbed belts in the deeper regions of the Skager Rack. The bottom is thus 

 everywhere in the Skager Rack on deep water, where I have been fishing, soft 

 clay, mixed with a little sand where the depth approaches 50 fathoms; the bot- 

 tom slopes very gradually from the shores dowu to 3 — 400 fathoms ; finally, the 

 deep Skager Rack offers, with respect to hydrography, no such sharp transi- 

 tions as the Cattegat. Though thus oue belt passes into the other out here, by 

 almost imperceptible degrees, it must be said that the differences between the 

 faunas on the different depths, e. g. on 275 — 300 fathoms and on 20 — 40 

 fathoms, are very considerable. I shall therefore, as far as it is possible for 

 me at this moment, try to give some of the most characteristic features in the 

 distribution of the animals, more particularly the fishes, in the various parts 

 of the Skager Rack. 



On the lower water, c. 20—35 fathoms, we have made but few 

 proper hauls with otter-seiue, Nr. 15, 19, 20, 21*). The fauna, evidently, 

 agrees very closely here with that of the Cattegat on the corresponding 

 depths. As, however, the sand-mixed clay deposits, go out on greater 

 depths in the Skager Rack (most likely because the influence of the
