HOWE : NORTH AMERICAN WOOD FROGS. 
N 
Ventral surfaces. Pale, light grayish white sometimes tinged 
with yellow or greenish. Throat mottled with dusky. 
Ilind legs. Faint yellowish. 
The distribution of this species does not, as far as known, extend 
north of Quebec, Can., south of South Carolina, or west of the 
Great Plains. Prof. E. D. Cope, Bull. 34, U. S. nat. mus., in his 
table of localities, includes one specimen each from the Selkirk 
Settlements, Can. (5381), Athabasca River, Can. (9384), Moose 
River, British Amer. (5922). Although I have not seen these 
specimens, I doubt very much their being Hana silvatica ; they 
are more probably liana cantabrigensis Baird.
