caught on deep water (10 — 38 fathoms), and most numerously on the deepest 



water. — Of the fry from the winter and spring 1893 I have in 1893 been 

 unable to find any trace anywhere in the seas. It must also, f think, live on 

 deep water; on shallow water it is certainly not in our seas. That it should 

 not live here at all is not likely, I think, as the one year old fry is found in 

 our seas as far into these as the northern parts of Funen and perhaps farther. 

 It is remarkable too. however, that we rind so few males of these fishes in 

 our seas; yet, according to FuUons's investigations on the coasts of Scotland, 

 this seems to lie the rule there also. 



The next series (a little more than 2 years till 2 1 /., etc.) is very common 

 in the tallies, and is nearly always caught together with the younger series; 

 it extends in summer over specimens between c. 5 — 8 inches, but neither this 

 nor Hie younger series has <tt the same time i[itil< the same sise everywhere in 

 tlw seas; there is for instance a perceptible difference in the size of the series 

 in the month of July (both in 1892 and in 1893), so that they seem retarded 

 in their development (particularly the younger series) in the deep seas of the 

 northern and eastern Cattegat (see in the table columns 5, 11, 12 from East 

 of La'so 27—38 fths. 1. July 92«, The Skaw 33 fths. 7. July 1893 . »North 

 of Anholt 21 fths. 21. July 1893«) compared to the other places, which are 

 all of them cither situated on much shallower water or at any rate (Lsese- 

 Rende) situated in such a way that the hydrographieal conditions are essen- 

 tially different from those of the former places. 



The deep places will lie influenced by the summer temperature much 

 later in the year and then in a much slighter degree; the winter temperature 

 on tlu' other hand is not so low at these places. Whether now this circum- 

 stance is decisive in this question I cannot tell, but the hydrographieal condi- 

 tions are on the whole very different at the said places. 



Among the specimens between 7V, and 13 inches 1 have found several 

 which had evidently lately spawned in spring, to judge from the large, 

 empty ovaries; a single female with running roe was found as late as 

 5. April 1893 at Kjerteminde. I must think, therefore, that their breeding- 

 season occurs in winter ami early spring; this agrees also with Scotch 

 statements. 



Why the large specimens are so rare is a question which has occupied 

 me much after my attention had first been called to it; this was not imme- 

 diately; as this fish plays such a small part in our fishery I originally took 

 but little heed of it. 



I do not know that I have seen any males larger than 8 inches; Fulton.
