Because of the slender nature of the gastrostyle and the rudimentary ring palisade, there is ample space surrounding the style within the gastropore tube. Although the ring palisade is visible from an apical view of the gastropore, the gastrostyle tip is slightly recessed below the coenosteal surface. The abcauline dactylopore spines (
