such pelagic eggs as those of the variegated sole, witch, mullet-like 
species and numerous ova of the dragonet. The period of the year 
is also more or less characterised by the occurrence of certain forms. 
Thus in January, off the east coast of Scotland, the eggs of rockling 
and plaice appear, followed by those of the haddock, bib, and long 
rough dab. In March and April the eggs of the cod, ling, dab, 
sprat, gurnard, lemon-dab, brill, and other forms are common. As 
the season advances the ova of the weever, whiting, dragonet, 
witch, sole, and solenette are found ; those of the turbot and 
topknot appearing towards the end of July.
