Ctratocephala n. g. 



This article on the new genus Ccratocephulu was read before the Western 

 Academy of Science, May 25, 1838. 



The name Ceratoccphala was proposed for a fossil from Springfield, 

 Ohio, well described and illustratecj. The original specimen which received 

 the name of Ceratocephaln goniata was a large head of a trilobite with 

 bases of conspicuous spines upon the occipital ring. The author illus- 

 trated the fossil in an inverted position and regarded the occipital sjiiues 

 as antenna-.
