1 Measured in per cent of total length of animal. 



2 Measured in per cent of total length of ovary. 



3 Distance from anterior end of ovary to anterior end of posterior fin 

 measured in per cent of total length of animal. The + sign signifies that 

 the ovary is anterior, and the — sign that it is posterior to this point.
