The test of this species is smooth and glossy in 

 appearance. The segments, which are hemispherical 

 or ovoid, are joined to form a short series ; adherent 

 to fragments of rolled phosphatic chips or shells, and 

 usually found in hollows or recesses in such frag- 

 ments, as if for protection. 



F. Icevis is found sparingly in various Cretaceous 

 beds, as the Marl of New Jersey, the Gault of Folke- 

 stone, the Greensand of Cambridge, and the Chalk- 

 marl of Kent. (Plate 11, fig. F.)
