descriptions of the species of Chelonian reptiles : the distribution of 

 the Saurians into their families and genera ; an essay on their or- 

 ganization and habits ; and a similar list of the books which treat 

 of them. 



The general observations are written by M. Dumeril ; while 

 every thing relative to the description and determination of the spe- 

 cies and their synonyms, has been left to M. Bibron, now his as- 

 sistant in the museum, and formerly the animal preserver of the de- 

 partment.* 



It is much to be regretted that M. Bibron, with the characteris- 

 tic inconsiderateness of a young naturalist, has deemed it necessary 

 to change capriciously many of the established family, generic and 

 specific names ; but in so doing he follows many of the modern 

 French authors, who thus affect to give a national character to their 

 works. Thus he has named anew all the families of the Chelonian 

 reptiles ; he has changed the name of the genus Chelydra of 

 Schweiger, which Fleming also had called Chelonura, to Emysaura ! 

 Trionyx of Geoffroy, which is the same as Aspidonectes of Wagler, 

 must now be called Gymnopsus ; and Emyda of Gray becomes the 

 Cryptopus of M. Bibron ! 



M. Bibron has followed the arrangement of the Chelonians pub- 

 lished by Mr Gray in his Synopsis Reptilium. He has given a very 

 extensive list of synonyms, copied in a great measure from the ela- 

 borate paper on the synonyms of these animals written by the 

 unfortunate Schweiger : and to those is added a very verbose de- 

 scription of the species. — J. E. G.
