Abstract Larvae of Boccardia knoxi (Rainer) were
reared in the laboratory after dissection from brood capsules extracted from
the outer shell and periostracum of Cookia sulcata and Haliotis iris
collected from Tasman Bay, New Zealand. All the eggs within each brood
capsule developed into embryos. The dissected larvae had provisional setae and
fed on phytoplankton. Larval development is described through to metamorphosis.
