: fig. 13c-d). A question about the peduncular pattern is if there are any changes in this pattern during the development? The three specimens record- ed have distinct sizes (tl of 29.5, 37.5 and 49.0 mm). If all the scales of the specimens are figured some differences can be observed. In the smaller stage the peduncular plate pattern is the basic eight-plate pattern with one row of rl-cl and another of sr-l-sc (
