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 



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

 whorls remain uncovered.
