. The natural history of Washington territory, with much relating to Minnesota, Nebraska, Kansas, Oregon, and California, between the thirty-sixth and forty-ninth parallels of latitude, being those parts of the final reports on the survey of the Northern Pacific railroad route, containing the climate and physical geography, with full catalogues and descriptions of the plants and animals collected from 1853 to 1857 . pon the inter-femoral region without beingcontinuous. I obtained numerous specimens of this singular animal in the vicinity of the Yakima river,in August, and saw them as far as latitude 48° 30 north, on the open plains, usually amongrocks and sand. They all had the gray color which they retain in alcohol, excepting one,which was of a brick red on the back, but beneath white, like the rest. These colors resemblethose of the stones among which they live, and it is supposed by some that they have thepower of changing their hue like the chameleon, and like the better known tree toad of theAtlantic States. Though ferocious in appearance they are perfectly harmless; j^et the Indiansbelieve them to have the power of producing a poisonous wound with their blunt spines, andit is possible that such a wound, if made, might sometimes be troublesome. They do notattempt to bite, and are so slow in motion as scarcely to get out of the way. They are, no T^S.^RE. E^. i SiirveAfs: Rppties: [-uiXn Xll. Ex. & Surveys; 47^rarallel Reptfles: Plate [V,
