So very little is known of this curious class of animals, that 

 it is impossible to say any thing with respect to the connexion 

 which exists between the families or orders; but that such 

 an affinity does exist must be obvious to every one who con- 

 siders the difficulty of distinguishing them. I have attempted to 

 bring together all the species that have been described of the 

 Siienidae and Amphisumidae, as Merrem (the last work published 

 on the species of Amphibia), describes only two of these animals. 

 It is to be hoped that Mr. Say and Dr. Harlan will continue 

 their researches, that have so much illustrated a group, which 

 has particularly attracted the attention of Ellis, Garden, Linnitus, 

 Cuvier, Schreiber, llusconi, and Sir Everard Home.
