WENONA PLUMBEA. (Baird and Girard.) 

 The Wood Snake. 



Not at all uncommon on the Sumass and Cheluk- 

 weyuk prairies; frequents dark shady spots, or long- 

 grass round the edges of pools. I never met with any 

 east of the Cascades. 



WENONA ISABELLA. (Baird and Girard.) 



Much the same in habits and distribution as the 

 above ; common in the woods along the bank of the 

 Chelukweyuk river. Both these snakes are also found 

 on Vancouver Island. 



BATRACHIA. 



ANOUEA (TAILLESS BATEACHIANS). 

 BUFO BOREAS. (Baird and Girard.) 



This toad is common east and west of the Cascades, 

 on the Sumass and Chelukweyuk prairies, in the valley 

 of the Columbia, and on the Spokan prairies ; fond of 

 lurking in damp, dark underbrush and long grass found 

 also on Vancouver Island. 



BUFO COLUMBIENSIS. 



The Columbian Toad. 



Very common along the banks of the Columbia, and 

 extending up the western slopes of the Eocky Moun- 

 tains ; fond of damp shady situations, especially the 

 wooded edges of pools and lakes ; in the summer time 

 it frequently goes into the water.
