Arbacia stellata (de Blainville, 1825)
Arbacia incisa Agassiz 1872 is probably a junior synonym for Arbacia stellata (de Blainville, 1825). Already Mortensen in his Monograph of the Echinoidea, II, page 577, had some difficulties, because both names were in use. He wrote: "In any case I think it objectionable, simply to use the name incisa, without giving at the same time the name stellata as a synonym, so that any body, also when not familiar with the object, may be able to see which species is meant with the name".
