A species of Eulalia, keying out as E. pusilla Örsted, 1843 in Fauvel (1923) and Hartmann-Schröder (1971), was collected at Plymouth in 1986. This species does not however agree with the original description, nor does it occur in the Danish waters from where E. pusilla was first described. The confusion apparently stems from Quatrefages (1865) and Saint-Joseph (1888) who both incorrectly applied Örsted's name to this more southerly species, the latter author providing the first accurate description.
