Two specimens, both clearly fossil, but from different deposits. 

 One apparently Cretaceous, the other probably from a Tertiary sand. 

 Both the specimens are quite plain ou the surface, and devoid of 

 the peculiar thickened and concentric ring of shell-substance which 

 Terqnem figures in his fossil specimens from the Eocene of Paris. 

 We have not observed this concentric thickening in any of the 

 numerous recent specimens from various Localities which have 

 come under our observation. The species, though never very 

 abundant, has a practically world-wide distribution.

The specimens are perfect and characteristic, and probably fossil. 

 The fine spines with which the specimens were originally covered 

 have been worn down, leaving nothing but a shagreen-like texture 

 of the shell. The specimens nre probably derived from Tertiary 

 sands, as they have the appearance characteristic of such fossils.
