Mr. Darwin found this species " in the island of Inchy, archipelago of 

 Chonos, north part of Cape Tres Montes, from the same great height as Bufo 

 Chilemis (from 500 to 2500 feet elevation) under a stone."

This species agrees in many respects with Litoria Americana of Bibron. It 

 differs, however, in the toes being much less palmate, at least according to the 

 generic character given by that excellent naturalist, and in the existence of 

 numerous thick glands on the posterior part of the thighs. The very slight 

 degree to which the extremities of the toes are dilated in the other species of this 

 genus, and which would at first sight lead to their allocation amongst the Rani- 

 form rather than the Hyliform group, is in the present species even more strongly 

 exhibited ; and it can scarcely be said that any dilatation exists at all. 



The colours in the only specimen brought by Mr. Darwin are much obscured. 

 The upper parts are apparently of an uniform brown, the under parts whitish, 

 dotted with brown. 



It was taken by Mr. Darwin at Concepcion, in Chile.
