Nederlandse fauna: Sepietta oweniana eruit. Rondeletiola minor nog niet erin!

After investigating literature and collections we show that Sepietta oweniana (d’Orbigny, 1839) should be removed from the list of the Dutch fauna. A sample collected in 1877 attributed to this species contains instead 2 specimens Rondeletiola minor (Naef, 1912). A male specimen of Rondeletiola minor has recently been found in the northern North Sea and is a new addition to the Swedish fauna and is reported here.
