This species has a confused history of description in the literature. In the last 25 years or so our understanding has improved a little, although the situation is still not fully resolved. Mackie (1984) gave a detailed description and drew attention to the downward-pointing neuropodial lamellae on chaetiger 2, among other things. This feature is present in the type material illustrated by Wirén, which has 6 pairs of branchiae. However, Mackie's figured specimens (not from the type locality) closely resemble Prionospio aluta Maciolek (1985). Sigvaldadôttir (2002) discussed P. cirrifera and P. aluta and placed them in synonymy. We believe that these species are separate and belong to a more inclusive complex of similar species; all of which have ventrally-directed neuropodial lamellae on chaetiger 2, though some may have more or fewer than 6 pairs of branchiae, with or without interparapodial pouches. Therefore, we can say that the description of P. cirrifera by Maciolek (1985) is incorrect. The figured ...
