DESCRIPTION OF A NEW ROCK-FISH OF THE GENUS 

 SEBASTODES FROM CALIFORNIA. 



B}^ Barton Warren Evermann and Edmund Lee Goldsborough, 



Of the United States Bureau of FisJieries. 



In connection with our recent studies of the fish fauna of Alaska and 

 the geographic distribution of the species of fishes known to occur in 

 the waters of that district, we examined and studied many specimens 

 in various collections from the coasts of Washington, Oregon, and 

 California. 



Among those from the California coast we find a species of Sehnstodefi 

 which appears to us to be new. The description of the type is here 

 given, together with a drawing by Mr. A. H/ Baldwin.
