20 BUFO AMERICANUS. 



2. The body is less full and bloated. 



3. Its motion and gait are much more lively and active. 



4. It differs entirely in having a spade-like process at the root of the first 

 toe, which in a measure approximates it to the Scaphiopus. 



Leconte first proposed calling this animal Bufo Americanus; and although he 

 has never published a description, still it is due to him to I'etain the name, which 

 seems to me sufficiently appropriate; for although there are many toads in the 

 United States, there are none so common, so widely extended, and so much like 

 the Bufo communis of the old world. Indeed, we regard it as the representative 

 of that animal in North America, and have taken it as the type of our genus 

 Bufo.
