or, as they said, into a fish. This error is now com- 

 pletely refuted. 



This frog is greenish, spotted with brown, and 

 particularly recognized by irregular brown lines 

 along its thighs and legs. It inhabits Guiana. 



There are many other foreign frogs, some of 

 which are very large, and as yet, but badly deter- 

 mined.* 



We may remark in the number,

 marbled with black.t 



Certain species have the hinder toes, almost with- 

 out palmation, but always greatly elongated. 1^ 



* N. B. A deeper examination, and tiie inspection of numerous batra- 

 cians brought to the Museum within a few years, have caused me to change 

 the favourable opinion which I had pronounced on the labours of Daudin. 

 What he has done is neither complete nor critical, and one half of his 

 figures, made after mutilated individuals, cannot serve for any precise de- 

 termination of the species. We may, however, except his hylcs, which are 

 much better made out than his frogs and toads. 



-}- I am convinced that in (he United States many species have been 

 confounded under this name, similar in size and colours, but differing 

 among other characters, in the relative magnitude of the tympanum. 

 That in which the tympanum is the largest has been designated by Merrem 

 under the name of Mugiens ; but its synonyms are not certain. The fig. 

 of Daudin, xviii., with a yellow stripe along the back, is a species of the 

 Indies. Add, Rana Palmipes, Spix, V. 1 ; i?» Tigrina, Daud. xx. ; E.
