Portion of the oral frame, in dorsal view, with disc removed, for different stages of development: A, 7 arm-segment stage; B, 13 arm-segment stage; C, >30 arm-segment stage; and D, >41 arm-segment stage. Abbreviations as in Figures 1 to 4; and GP represents genital plate; GS, genital scale; MS, interradial muscle scale. Scale line is mm. Note that buccal scales, which lie on the oral surface, cannot be seen in C or D. Dotted lines separate DOP and POP. the first buccal tube-foot scale

Portion of the oral frame, in dorsal view, with disc removed, for different stages of development: A, 7 arm-segment stage; B, 13 arm-segment stage; C, >30 arm-segment stage; and D, >41 arm-segment stage. Abbreviations as in Figures 1 to 4; and GP represents genital plate; GS, genital scale; MS, interradial muscle scale. Scale line is mm. Note that buccal scales, which lie on the oral surface, cannot be seen in C or D. Dotted lines separate DOP and POP. the first buccal tube-foot scales (corresponding plates have been treated as ventral arm-plates or homologues of anilmlacral plates by various authors). By the 9 arm-segment stage, due to growth of the adoral shield, the adoral shield spine sits near the center of the shield plate (Fig. 4). It then acts as a "tentacle scale" for the second buccal tube-feet, analogous to the minute plates on.
