Ceratocephala n. g. 



This article on the new genus Ceratoce])hala was read before the Western 

 Academy of Science, May 25, 1838. 



The name Ceratocephala was proposed for a fossil from Springtield, 

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

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

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

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

 as antenna-.
