the result thai I found none or only very few*); whether they bore down 

 into the sand so that the seine cannot fish them, or whether they go out 

 on deeper water where I have had no opportunity of fishing in winter-time, 

 I cannot tell. The fishermen believe that they go down into the sand, and 

 I should feel most inclined to think so too. We must then content our- 

 selves with looking for them in spring, hut they do not then any more 

 belong to the 0-group, hut to the 1-group, lor they are now on an average 

 more than one year of age. 



We left them in the autumn 1892 a* fish of 2 — 4 inches (table VI. co- 

 lumn 19. 2ft), and find them again in the northern Cattegat at Bangsbo in 

 May 1893, as fish of 2 — 4 inches in length, under which the new 0-group 

 is clearly to he seen (table III, column 1, etc.). In the course of the sum- 

 mer, however, they disappear from the sea-shore (see table III), and give 

 room for the 0-group; for they are becoming rarer the later in the year 

 I hey are examined. Winther, loc. cit.. p. 314, seems to have seen some- 

 thing like this in the Sound. There is then an emigration of these fish 

 from the shore, and it has commenced, perhaps, already in the winter. 

 In order to follow this emigration an investigation of the seas at Aalbsek 

 was undertaken in July 1893, table IV. It will he seen in the columns 

 2 — 3 — 4 — 5 — 0. distributed according to the depths, that the plaice are 

 larger the farther we are going out. and if we make a summary of these five 

 columns (column 1). there is besides the 0-group a 1-group from 2 1 / 2 - — 2 

 inches, and a 2-group (or part of one) from G 1 /, — -10 inches. I am 'sorry 

 to say that the investigations were not carried on farther off on still deeper 

 water: these two amalgamated groups would then perhaps have been better 

 represented, i. e. the larger specimens belonging to the 2-group would then 

 perhaps also have been there. 



I have once before. 1892, attempted such an investigation with a series 

 of draughts from shallow to deeper water, table VI, column 3 — 8. suffering 

 the 2-group to be represented by fish caught by the fishermen in plaice- 

 seine with large meshes, column 3 in the table. Owing to great haste 

 these fish were badly measured (see the table), hut the summary-column 8 

 shows clearly a 2-group which is pretty clearly distinguishable from the 

 1-group. Here now is the remarkable circumstance that, though the inve- 

 stigations this year, 1892, were carried on earlier in the year (March) than 

 in 1893 (July), the specimens of both groups are evidently larger, and the 

 point at which the two groups meet is one inch above that of 1893. viz. at 



This year lin the winter 94 I have succeeded however in finding these little tislies 

 at Snekkersten and Kjerteminde. This winter is uncommonly mild.
