Two atrial hexactine pinules. C. A choanosome diactin, whole and enlargements of the tip and center. D. Hypodermal pentactin, whole and enlarged tangential ray end. E. Two whole hypoatrial pentactins showing different lengths of proximal rays, and enlargements of the ray ends. F. Choanosomal hexactin, whole and enlargement of a ray end and the coarsely spined central area. G. Discohexactin and enlarged ray end (all whole microscleres at same scale). H. Hemidiscohexaster. I.
