Secondary septa were continuous with the interlamellar septa (Figs. 3, 4) and lacked any apparent openings or ostia leading from the secondary water tubes to the brood chambers, effectively isolating the developing larvae from water flowing through the mantle cavity and the secondary water tubes (Fig. 6). Secondary septa also lacked the cil- iated cells present on the lamellar walls of the primary and secondary water tubes (compare Figs. 5. 6). The interlamellar septa of
