*Oken, Isis, 1817. In Isis, 1817, immediately following the publication of the 

 Regne Animal, Professor L. Oken recapitulated the genera of Cuvier, giving Latin 

 forms to those left by the author with French names only. These occur on pages 

 1181, 1182, and 1183 (misprinted in the text as 1781, 1782, and 1783). Several of 

 these were also Latinized by Cloquet, Dictionnaire d'Histoire Naturelle, in 1817, 

 but the date of Oken is earlier. Still others were Latinized by John Stark, Ele- 

 ments of Natural History, Edinburgh, 1828, vol. L 



As the question of priority is not affected, we leave the names of Cuvier latin- 

 ized by Oken in their proper sequence.
