A slight imcrease in the number of pelagic eggs usually 
occurs early in February, and becomes more marked towards 
the end of the month. The species of fish represented do not 
appear to materially increase. We find this to be the case 
year after year, and only about three or four species are repre- 
sented by their eggs in the plankton. The coarse nets caught 
nearly 6°3 eggs per haul, and the fine nets nearly 1:7 eggs per 
haul. The average catch of the coarse and fine horizontal 
surface hauls amounted to 4 eggs for each combined sample. 
The rockling eggs were fairly uniformly distributed throughout 
the month. The single specimen of the plaice ege was taken 
on February 19th.
