A single specimen, fossil. This may be derived from Gault or 

 lower Cretaceous formations, to which zones the species appears to 

 be confined.

Many fossil specimens, well preserved, and apparently from a ' 

 shell-sand. The specimens are small compared with those 

 commonly found in recent deposits. It is widely distributed at 

 the present day within the tropics and at all depths down to 

 2750 fathoms. Of its fossil distribution, Brady only records its 

 occurrence in the limestone from New Britain, in the Pacific, as of 

 unknown geological age, but its records may very possibly be 

 confused with those of its older and better known ally, Pulvinulina 

 menardii, of which it is merely a turgid and solid form, and which 

 has been recorded as far back as the Cretaceous period.

One fossil specimen from above the Selsey beds, opposite Wes c 

 Street. This species, now known only from deep water in the 

 great oceans, occurs in many Teritary deposits on the continent of 

 Europe.
