Both specimens seem to be young, the largest one having only a length of nearly 

 8 Mill., those described by Smith of 13 Mill., but the description agrees in every particular, 

 especially the presence of an internal septum, as in the genus Septaria, is very characteristic. 

 The "Investigator"-specimens have been dredged in the Laccadive Sea at 105 fathoms and in 

 the bay of Bengal, at 410 fathoms.

This species has only been recorded from the Philippines. A very young specimen 

 from Stat. 313; has a nearly smooth base, under the lens a row of beads borders the umbilicus, 

 a few very faint spirals surround it and still fainter growth-striae, elegantly curved, make their 

 appearance, the upper surface is quite covered with small stones and large foraminifera, only 

 the nuclear whorls remain uncovered.
