Abstract
The adults of three populations of the spionid polychaete Scolelepis squamata were studied throughout a year in Barbados. From quantitative estimates of gametes and numbers of breeding animals, four statistically reliable outbursts of spawning were determined, each about 2 months apart, followed by a cessation of breeding activity from November till February. Spermatophores of this species were described for the first time; they occurred at each of the four spawning times.General observations on the ecology and reproductive morphology of this species were made. Two varieties of this species were found; their possible relation to the species in the literature was considered.
