Sumass, and on the trail that crosses the Cascade range 

 from Fort Hope to Colville. 



All the Grarter snakes found along the course of Bndy. 

 Line are very similar to each other, not only in habit 

 but in the distribution of the markings ; all are harm- 

 less, and may be handled with impunity. 



PETUOPHIS WILKESII. (Baird and Gfirard.) 

 Oregon Bull Snake. 



This snake attains a much larger size than any other 

 species in this district; I have frequently seen them 

 three or four feet long. The snake is common on 

 both sides of the Cascades ; in the spring it keeps on 

 the grassy prairie land, but in the hot weather retires 

 to the shores of lakes and ponds, or the margins of 

 streams, and spends much of its time in the water. 

 Although quite harmless, it assumes a most menacing 

 attitude when suddenly surprised on the open plain, 

 curling itself up into a spiral, and hissing furiously. 

 I obtained one very large specimen near Colville, 

 another at Sumass, and a third near the foot of the 

 Gralton Mountains. I never saw it on Vancouver Island, 

 although I think it is very likely that it lives there in 

 the open valley land. 



I obtained another species of Petuophis, but it has 

 not yet been determined or named. 



ELGARIA GRANDIS. (Baird and Girard.) 

 Banded Elgaria. 



I obtained this beautiful lizard at the Blacksmith's 

 Camp, on the Chelukweyuk river; I also saw it at
