Calcified larval and juven structures are revealed In polarized light. \t the posterior end of the larva, two juvenile to the posterior transverse rod. The bases of right postoral and posterodorsal rods are po periphery of the juvenile aboral surface to either side of a pan of the posterioi transvi 5 hours after metamorphosis. Numbers 1-5 indicate genital plates; four of these form from elements. D. E.

Juvenile, two days after metamorphosis. I he apical system has almost completed filled the aboral surface. Adult spines can be seen at the circumference of the test and have a verj different morphologj from juvenile spines.
