fouad everwhere in summer where there is rich algal vegetatiou at low water or 

 a considerable bed of washed-up Zostera on the beach. As mentioned it was 

 represented this j'ear by very small numbers in Odense Fjord at Seden Strand at 

 the end of May; in June I searched in vain for it in Klosterhavn at Nykjøbing 

 Mors; and at Lindholm uear Stege only a few specimens of it were taken in the 

 beginning of the same month. 



II. (ironp. 



The specimens of this year's group have been 2 years in our waters on 

 the Ist of May (date of immigration). 



The eels have now become quicker in their movements and are more 

 distributed, so that one cannot catch the same quantities of them with the shrimp 

 shove-net as of the previously mentioned annual groups; thus in several of our 

 tables this group is very slightly represented, e. g. Table 7. — Nevertheless there 

 can be no doubt about the lower limit of the approximate average size of its 

 specimens; this appears partly from what has been said abo'se regarding the limits 

 of the I group, and \ve must therefore place the lower limit of tiie II group on 

 the date of immigration in spring at ca. 9V2 cm. and its maximum at ca. 13 cm.
