IX. RESULTS OF AN ICHTHYOLOGICAL SURVEY ABOUT 

 THE SAN JUAN ISLANDS, WASHINCxTON. 



By Edwin Chapin Starks. 



The following pages embody the results of a study of a collection 

 of fishes made about the San Juan Islands in the summer of 1909 

 by the author while a member of the Puget Sound Marine Station. 



The San Juan Islands are situated just north of the Strait of Juan 

 de Fuca, and opposite the lower end of Vancouver Island. The 

 marine station is located at Friday Harbor on San Juan Island, but 

 during the summer it was temporarily moved for a part of the time 

 to Olga on Orcas Island. 



Part of the equipment of the biological station was one of the 

 powerful little steamers regularly employed as dredging boats in the 

 shrimp-fishery. She was equipped with a shrimp-dredge or trawl, 

 measuring twelve feet across the mouth, and with a hoisting engine 

 and sufificient steel cable to dredge in depths up to forty-five fathoms. 

 By this means all of the deep-water species were taken. 



The author wishes to express his obligations to the individual 

 members of the station for their interest and help in obtaining and 

 preserving these specimens, as well as for the many courtesies and 

 privileges of the station extended to him. 



He wishes further to express his obligations to Dr. Bashford Dean 

 for financial aid through the American Museum in New York, en- 

 abling him to carry on seining operations on the beaches and also to 

 the two students of Stanford University, Messrs. Launce Scofield 

 and Henry Poor, who gave assistance to that end. 



Acknowledgment is also due to the members of the Department 

 of Zoology of the University of Kansas, who contributed a collection 

 of fishes largely made on the shrimp-boats, while the latter were 

 pursuing their regular occupation of dredging for shrimps. Among 

 these was a new species of Sebastodes. 



Besides the methods already indicated collecting was done with 

 the aid of set-lines and gill-nets, and several species were only taken in 

 pools left by the receding tide, and under the rocks, at low tide.
