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. 
SCELOPORUS OCCIDENTALIS. 
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 @raciosus. (Baird and Girard.) 
Slender Fence Lizard. n 
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. 
URADELA (TAILED BATRACHIANS). 
TARICHA TOROSA. (Gray. Cat. Brit. Mus. 11-1656, p. 25.) 
The Warty Salamander. 
A widely-distributed species found east and west of 
the Cascades, and on the western slope of the Rocky
