The spiral sculpture of the base is but faintly developed; this may be due to the youth 

 of the specimen, moreover a large part of the basal surface is broken.

The specimen is also very young, the foreign bodies consist of a nearly equal number 

 of Foraminifera and fragments of shells and stones.

Two of the specimens are very young, measuring without the spines only about 22 and 

 20 Mill. In this juvenile state, the sculpture of the base, so conspicuous in adult ones, is nearly 

 wanting; it consists of short striae radiating from the umbilicus, crosseel by a few (3 or 4) spirals 

 and leaving a large part smooth, unless for very faint, curved, growth-striae, a little more 

 conspicuous at intervals. The third specimen, though not large, is very characteristic.
