The species, about which more data should certainly be obtained, are 

 the turbot, brill, and ling ; and the districts further from shore than those 

 here dealt with, will have to be investigated for this purpose. A research 

 of this kind would probably throw light on the later stages of these 

 species as well, and might also clear up the ignorance regarding the hali- 

 but. 



It was intended that this review should also include the areas of St 

 Andrews Bay, Moray Firth, and the Clyde, but the detailed examination of 

 the Firth of Forth has prevented the inclusion of the St Andrews Bay 

 data here. The general spawning-system appears to be much the same in 

 many respects as regards the Moray Firth and the Clyde ; the few observa- 

 tions that have been made have revealed some remarkable differences 

 from the Forth system, though the fact of their paucity prevents the issue 

 of statements which could carry any weight. It is thus best to leave 

 them out of consideration for the present.
