ECHINOCORYS. 



This genus was well established by Breynius, in 1732, and illustrated with good 

 figures ; it is to be regretted that Lamarck, in 1801, suppressed the name Echinocorys, 

 and proposed, without any reason for it, that of Ananchytes, now so well known to all 

 geologists ; still, in justice to Breynius, I am under the necessity of restoring his name in 

 order to carry out the principle which has guided me in the nomenclature I have adopted 

 throughout this work.
