ORDER BATRACHIA. 397 



The Blue and Yellow Frog, (Sh. H. Bicolor, Daud. 

 viii. and Spix xiii.) 



Celestial blue above, rose-coloured underneath ; 

 from South America. 

 One still larger is, 



The Zebra Frog, (Sh. R, masina, Linn. Hylce pal- 

 mata, Daud. xx.) 



Striped irregularly across with red and fawn-co- 

 lour ; is of North America.* 



We may also remark in consequence of the sin- 

 gular property which is attributed to it. 



The Tinging Frog, {Mana Tinctoria, L.) 



Whose blood, inserted into the skin of parrots, in 

 the places where some feathers have been plucked 

 from them, causes red or yellow feathers to come 

 instead, producing on the bird a parti- coloured 

 plumage. We are told that this is a brown species, 

 with two whitish bands, united crosswise in two 

 places (Daud. pi. viii.) ; its hind feet have the toes 

 almost free.t
