a length of c. 11 inches. A third grown-up (mature) annual series and perhaps a 



fourth are most likely represented by the specimens from c. 12 — 23 inches. 

 The milters do not seem to reach the spawners in maximum seize, nor do 

 they reach them in average size. The largest spawners I have measured are 

 c. 26 inches, the largest milters only c. 23. The fish is thus scarcely as large 

 as Bhombus maximus, and particularly not so weighty. 



The spawning-time agrees with that of Bhombus maximus: May — July; 

 in that period spawning individuals are not rare in the Cattegat. Its eggs 

 are larger than those of Rhombus maximus. Also this fish is said to have 

 suffered much from the too eager fishing in the Cattegat in these later years. 



It is scarcely so numerous in the Cattegat as Rhombus maximus; in our 

 narrow seas in towards the Baltic, it is at any rate much rarer, and in the 

 Baltic Sea it is found even far more rarely than I!li<>ml>iis maximus. It will 

 lie perceived that the 2nd annual series of this species of fish, like that of 

 Rhombus maximus, is particularly abundantly represented in the seas about 

 Grenaa where they are fished much with gill-net. This may be looked upon, 

 perhaps, as a parallel to the fact that the younger annual series of the the 

 plaice (not the youngest though) in our inward seas (particularly in the Bal- 

 tic east of Sealand and Falster) were so numerous, and that the older fish 

 must be supposed to emigrate from tins place to the Cattegat. 



The Norvegian Topknot (Zeugopterus norvegicm). 



Of this rare flounder, which is of no value for the fishery, two specimens 

 were taken during these investigations, both east of Lajso, on the 1. July 1893, 

 i>n a depth of respectively 27 and 3s fathoms. Our two other species of this 

 genus, Z. megastoma aud Z punctatus, are very rare; nay. I have seen only 

 one single little specimen of the latter in the Cattegat in these 10 years, and 

 the former 1 have never found. They are of no interest at all to our fishery. 



The Megrim (Amoglossu.s laterna). 

 24. June 92 were found 2 specimens N. of Anholt lighthouse on lOfaths. of water.
