308 APPENDIX. 



Walla-walla on the banks of the Columbia. The hot 

 sandy plains about Walla-walla seem to be a favourite 

 haunt for several species of lizards. The wild sage grows 

 about in tufts or patches, and under the roots live the 

 lizards: the sand is covered with their tracks; they are so 

 sharp and active that it is very difficult to catch them. 



SCELOPOEUS OCCIDENTALS. 



Western Fence Lizard. 



This lizard is very common on the sand plains along 

 the banks of the Columbia river. I also obtained it at 

 Colville (altitude above sea level 1,268 feet). I never 

 saw it west of the Cascades, although Dr. Suckley 

 mentions it as being found at Steilacum. Its habit is 

 to frequent dead timber and to hide under stones and 

 fallen logs ; it often climbs into the pine trees, and all 

 its motions are very agile and graceful. 



SCELOPORUS GRACIOSUS. (Baird and Grirard.) 

 Slender Fence Lizard. 



This lizard is very common on the large masses of 

 basaltic rocks * that start up like ogres' castles on the 

 sand plains between Walla-walla and Colville. I saw 

 a great many of them at the Snake river ferry, on the 

 rocks about the Pelouse river. 



UBADELA (TAILED BATEACHIANS). 



TARICHA TOROSA. (Gray. Cat. Brit. Mus. 1 1-1656, p. 25.) 



The Warty Salamander. 



A widely-distributed species found east and west of 

 the Cascades, and on the western slope of the Rocky
