BLACK-STRIPED FROG. 137 



The following somewhat doubtful or not well- 

 determined species are mentioned by Mr. Schnei- 

 der, in his publication on the Amphibia. 



PUNCTATED FROG. Raua Punctata, 



Colour whitish grey, with small, irregular, 

 snow-v/hite specks on the head and back, and a 

 snow-white band from the eyes to the hind legs : 

 gape running beyond the eyes : abdomen and thighs 

 beneath thickly beset with calli or papillae : body 

 very thin near the thighs. Mr. Schneider speaks 

 of a drawing of this species, which represented it 

 of a brown colour, instead of grey ; so that the 

 colour of the first described specimen might, per- 

 haps, have been changed by being preserved in 

 spirits. 



BLACK-STRiPED FROG. Raua Melanorabdata, 



Among some drawings executed in Brasil by 

 the command of Prince Maurice of Nassau, pre- 

 served in the Royal Library at Berlin, this species 

 occurs, but unaccompanied by either name or de- 

 scription. The head and back are green, with trans- 

 verse black bars. Perhaps, says Mr. Schneider, it 

 may be the same with a Frog described by Marc- 

 grave, under the name of Rana arborea mediocris 

 magnitudinis, tota ex flavo albicans superius, at 

 inferius per totum lutei coloris : crura postica me- 

 dietate inferiore etiam lutei coloris, sed trans- 

 versim lineis nigris variegata, ut et latera ventris.
