 hand side of the figure, instead of the upper side.) 



Fig. 2. Median vertical section of another specimen. Showing the vesicular tabulae and 



dissepiments and the thickened columellar septum. x 3/2. 



Figs. la-Id. Serial transverse sections from the same specimen as fig. 2. Epitheca only 



complete in fig. 2ft. The LopliophyUum stage, with the septa extending to the columella, is seen in
