Frequent, both recent and fossil. The fossil specimens are of the 

 massive labyrinthic type, whereas the recent ones are of the depressed 

 encrusting type. Some of the recent specimens show the regular 

 truncatuline arrangement of the chambers figured by Sidebottom 

 from the Delos specimens. 



Eecorded by Millett — rare.

Fossil only. The specimens are apparently derived from at

 Apparently a recent specimen, although the form is usually a deep- 

 water type round our coasts.
