Vermiliu triquetra. Recent. 

 — — hicarinata, Lamk. ? Recent. 



Balanus ? I found at least six species, one of which I am in- 

 formed by Professor Agassiz is. common in the Molasse, another 

 agrees with one from Bordeaux in my possession. As Basterot's 

 catalogue of Bordeaux fossils does not include Balani, it is im- 

 possible to say whether any of the others are to be found in that 

 locality.
