Remarks. — -The occurrence of the above minute species is 

 interesting as extending its range in time. It was previously 

 recorded from the neocomian of England, besides being well- 

 known as a tertiary fossil.

Remarks. — This is another species which now has its range in 

 time extended, since it was previously known only from the 

 English neocomian of Surrey and the gault of Kent, as regards 

 mesozoic strata. It is also a tertiary fossil. The example 

 before us shows all the characters of the species, and especially
