Nordsøen, Skagerak og Østersøen pelagisk tagne Former af de her 
omhandlede Ordener. En Hovedgrund er, at jeg ved et foreløbigt 
Forsøg fandt, at Udbyttet vilde blive yderst magert i Forhold til 
den Tid, et Gjennemsyn af de talrige Lister vilde kræve. Heller 
ikke følte jeg mig fuldt overbevist om, at Bestemmelserne af det 
ringe Antal af Arter hørende til flere Ordener altid var fuldt paa- . 
lidelige, thi Fejl indløber lettere ved Bestemmelse af enkelte 
Former end ved en systematisk Bearbejdelse af et stort Materiale 
bestaaende af talrige Arter.
