Remarks. We do not distinguish subspecies of S.

dehiscens in the present study. Specimens from the sequence studied are primitive in that the opening of encrustation is not broad, so our material include the primitive subspecies S. dehiscens immatura (Cushman) (e.g., Natori, 1976, pl. 1, fig.

5), while the advanced subspecies S. dehiscens excavata Banner and Blow (e.g., Natori, 1976, pl.

1, fig. 7) has not been observed.

Occurrence. Common in the upper part of the

Yonahama Formation and the Minebari Formation.
