NOTES ON THE FISHES OF CRAB CREEK, WASHING- 

 TON, WITH DESCRIPTION OF A NEW V 



SPECIES OF TROUT.* V'^/^/'' ' 



BY BARTON WARREN EVERMANN AND 

 JOHN TREADAVELL NICHOLS. 



Reports having come to the Bureau of Fisheries from time to 

 time of the presence of a peculiar and interesting trout in Crab 

 Creek, Washington, it was decided to secure specimens of it 

 whenever a suitable opportunity presented itself. 



In the summer of 1908, while Mr. Nichols was engaged in 

 studying the operation of the salmon wheels on the Columbia 

 River, advantage was taken of his presence in that part of the 

 country to visit Crab Creek, make a study of the local condi- 

 tions and collect specimens of the trout and other fishes inhabit- 

 ing that stream. Accordingly on July 29 Mr. Nichols, accom- 

 panied by Mr. Ruskin Lhamon as temporary assistant, drove 

 from Ritzville northward al)out 12 miles to Rocky Ford where 

 Crab Creek was examined and collections made. The road from 

 Ritzville is through a very dusty rolling grain country. At the 

 point visited Crab Creek runs in the bottom of a coulee appar- 

 ently cut ))y a much larger stream. Along its immediate banks 

 is a green strip of small trees and shrubs, willows, poplars and 

 alders, but the rocky slopes and ledges of the coulee rise toward 

 the upland, uncultivated and scantily clothed with grey -green, 

 rank-smelling sage brush, dazzling to the eye under the desert 

 sun. The water of the stream was clear and cold, about 53° 

 Fahrenheit. Its shallows were overgrown with water crowfoot 

 in flower. 



Several species of wading birds were observed, such as kildeers
