My late friend Dr. Kuhl has noticed another genus of this 

 family under the name of Occidogynaj but he only observes that 

 the body is regularly oval, and that the hind legs are peculiar 

 and intermediate between the frogs and toads.

The axolotle appears to be the larva of an animal of this genus, 

 although Sir E. Home has discovered that it contains eggs, fdr, 

 according to Baron Cuvier, they are- to be found in the tadpoles. 

 The Sirex opercularis of Beauvois (Phil. Trans. Philad.) and th6 

 Proteus New Csesariensis oi Green (Jour. Acad. Nat. Sci. Phil.) 

 appear also to be larvae. The Trois doigts of Lacepede is said 

 to be a true lizard. Latreille formed the genus Idiytheosaurm 

 of the larvsD of this genus.
