far as the investigations go we may divide the murænoid species 
into two groups: 1) those spawning in or rather over great depths 
and 2) those spawning in shallow water. To the former belong 
Conger vulgaris, C. mystax and probably also the fresh-water eel 
(further the parent forms of L. lanceolatus and ingolfianus), to the 
latter Muræna helena, Ophichthys serpens and other Ophichthys- 
species, the eggs of which I have been able to identify. The 
latter spawn in shallow water, inside the 200 or even the 100 m. 
lime where their eggs and tiny larvae occur at the surface together 
with larvae of true coastal forms.
