CHRONOLOGICAL LIST. 33 



The only synonymy introduced in the Chronological List is the adding of the original specific 

 name to a synonyme when it first appears. Thus, in Lamarck, 181 G, we find, 



Ecltinus 



neglectus! = Echinus Diobachiensis Mull. 1776. 



Showing that Lamarck described as a new species what had already been described as Echinus 

 Diobachiensis by Mullek, or that I consider it to be the same species, which may or may not 

 be a correct view. 



Typographical errors figure as new names, and are denoted as follows: under Forbes, 1844, 

 we find, 



Amphidotus (err. typ.) Amph.id.etus Agass. 1841. The correction is at once indicated. 



The light and heavy type are used throughout the book to denote the relations the specific and 

 generic names bear to the authority of the special case, but it does not necessarily follow that 

 because we write Encope micropora. under Agassiz in 1841, Mon. Scut., that the genus 

 Encope was not established by him ; it merely denotes that he described as belonging to Encope 

 the species micropora, at a different period or in a subsequent paper to the one when Encope 

 was first established. See 1840, Agassiz, Cat. Syst. Ectyp., Encope grandis, where the genus 

 was first named. 



In the Chronological List fossil genera have been introduced in their proper order.
