This toad, the common toad of Oregon and Washington, has 

 a representative in the southern part of the Pacific Slope, Bufo 

 boreas nelsoni Stejneger. The type specimen was found in 1891 

 at Oasis Valley, Nevada. It is similar to Bufo boreas, except that 

 the skin is smoother between the warts, the toad has a longer, 

 more pointed muzzle, and the longer legs have a less-indented 

 web and a smoother sole. Bufo b. nelsoni is found east of the 

 Sierras, in the high altitudes of southeastern California and west- 

 ern Nevada.
