A NEW LUGWORM FROM WOODS HOLE, HITHERTO INCLUDED IN ARENICOLA CRISTATA (POLYCHAETA)

Authors


Abstract

The Woods Hole fauna contains two distinct species, both conforming to the current diagnosis of Arenicola cristata Stimpson. In the absence of Stimpson's original material, one of them is identified with his species on the basis of his descriptions. The other is described as Arenicola caroledna sp. nov. Their distinguishing characters have not previously been regarded as of taxonomic importance so it is often impossible to tell from the literature alone whether a record of “Arenicola cristata” refers to cristata in the strict sense, to caroledna or even perhaps to some other form.
