Test in front view oval, in end view irregularly globular ; chambers 

 very tumid; suture slightly depressed, in side view the last-formed 

 chamber at the aboral end somewhat curving out over the preceding 

 chamber; wall smooth, white; aperture semicircular, with a simple 

 flat tooth filling a large part of the opening. Length, about 1 mm. 



Specimens that seem to be the same as the specimens described by 

 Bornemann from the Oligocene of Europe, and recorded by Schlum- 

 berger from off the Azores, are found at numerous stations in the 

 Albatross collections but not in the shallow- water samples. The 

 typical form has a flat tooth largely filling the aperture. The speci- 

 mens figured from the Philippines do not have this typical tooth but 

 are otherwise similar.
