a mile from the banks of the Elwah river, and some seven miles 

 from Port Angeles. Unlike the generality of toads, it takes 

 readily to the water, in which its long, slender, webbed, frog-like 

 hind feet are admirably adapted. It grows to a large size, 

 and the bold markings of the belly make it a very conspicuous 

 object." (D. G. E.) 



REPTILIA. 

 Thamnophis pickeringi B. & G. 



Preorbital retains its width to middle of orbit, then slightly 

 narrows ; middle postorbital slightly the larger. No. 489 has a 

 small scale just behind lower and middle postorbital, evidently 

 a part of first temporal ; head is fairly well differentiated from 

 the body ; lower row of scales on each side larger than on second, 

 especially on middle portion of the body, only a few being 

 slightly carinated ; most of the scales on tail carinated. 



Color in alcohol, dark greenish above, bluish below ; a dorsal 

 bluish band covers one, and half of two other rows of scales; lateral 

 stripe on 2d and lower half of 3d row of scales. These three 

 stripes less prominent on the posterior part of the body, and 

 disappear on the anterior half of the tail. About 76 orange bars 

 on body, which do not extend on the tail ; these bars are irregular, 

 about one scale wide, and on 3d, 4th, 5th, and 6th rows of scales. 

 Very few can be seen on No. 489. No stripe behind the eye, and 

 no black spots on the body ; belly not marbled with darker. 



"Snakes are not common in the Olympic Mountains, and no 

 poisonous species is found there. The specimens given in this 

 paper are all the species we saw, and were taken at various 

 heights from 500 to 5,000 feet and it is probable that they 

 represent all that inhabit at least that portion of the range ex- 

 plored by myself and party." (D. G. E.)
