A NEW ECHINOCORYS FROM BOLIVIA 231 



the European Danian species, E. sulcatus Goldfuss, but it appears to 

 be most similar. to the European Campanian and Maestrichtian 

 forms, E. CoUeaui and E. Duponti, described by Lambert, who 

 prefers to use the generic term Echinocorys proposed in pre-Linnean 

 time (1732) by Breynius, and re-adopted in 1778 by Leske, rather 

 than Ananchites Lamarck (1801) which has been adopted in recent 

 American texts. The age of the Bolivian deposit would appear 

 to be Campanian, although more definite confirmation is desirable 

 before this correlation can be accepted as final.
