Sean,
In addition to the references already posted, a few
more useful ones are the following:
Lacalli, T.C. 1980. A guide to the marine flora and
fauna of the Bay of Fundy: polychaete larvae from
Passamaquoddy Bay. Canadian Technical Report of
Fisheries and Aquatic Sciences 940:1-27.
Bhaud, M. and C. Cazaux. 1987. Description and
identification of polychaete larvae: their
implications in current biological problems. Oceanis
13(6):596-753.
Blake, J. 1975. The larval development of
Polychaeta from the northern California coast III.
Eighteen species of Errantia. Ophelia 14:23-84.
Cazaux, C. 1968. Etude morphologique du
devellopement larvaire d'annelides polychetes
(Bassin d'Arcachon). I. Aphroditidae,
Chrysopetalidae. Arch. Zool. exp. gen. 109:477-543.
These are all useful for getting larvae down to
family, but unless there are descriptions of larvae
available for worms from your region, identifying
to species will be pretty hard, at least with the
scaleworms.
