We have had no difficulty in finding the bottom stages of the Lumpenus. 

 They hve together with the older annual groups od the soft, covered gi'ound in the 

 western and true Baltic. Here they pass their whole life after the pelagic stage 

 is ended. We can therefore obtain all the different groups in the same haul
