EXPLANATION OF PLATES 



The figures are intended to show the comparative size.s of the eggs of gadoids and pleuronectids. All 

 are drawn to the same scale of magnification (X 30). Average sizes are given, but it should be understood 

 that an exact arithmetical average has only a very limited meaning, as it is not the same in the different 

 phases of the spawning-time (cf. the Tables). 



The literature notices refer to the best available figures of the various species, and the sizes given here 

 have for the most part been taken from these figures.
