ern Bering Sea, through the Gulf of Alaska, to southeast 

 Alaska. Other documented records extend its range south 

 to Johnstone Strait, British Columbia (Peden and Wilson, 

 1976; Fig. 4). It is common throughout its range in shallow 

 rocky habitats, and our material was collected at depths 

 from 5 to 160 m, its total recorded depth range. 



Sebastes ciliatus is commonly collected with S. melanops 

 by trawl and hook-and-line gear in shallow waters, where 

 S. ciliatus is commercially fished as part of the "black 

 rockfish" fishery and has been often misidentified as S. 

 melanops. In deeper (>100 ml trawls in Aleutian and Gulf 

 of Alaska waters. S. ciliatus is commonly found in asso- 

 ciation with S. alutus (Pacific ocean perch), S. polyspinis 

 (northern rockfish), and S. variabilis (dusky rockfish). Less 

 frequently, S. uariegatus (harlequin rockfish), S. zacentrus 

 (sharpchin rockfish), and S. proriger (redstripe rockfish) 

 are also captured with S. ciliatus. A large (320 mm; UW 

 47417) S. ciliatus was found in the stomach of a Pacific cod 

 (Gadus macrocephalus) collected in the Aleutian Islands. 



Females captured in summer (May- July) trawl surveys 

 are most often ripe with eyed larvae. Near-term females 

 and males were observed in July in shallow waters off 

 southeast Alaska in contrast to individuals of S. variabi- 



lis, which were all immature at this time (Orr, personal 

 observ.). 



Etymology 



The specific name ciliatus is derived from the Latin word 

 "cilium" for "eyelid" or "eyelash" and alludes to the numer-
