THE FISHES OF ALASKA. 287 



The red rockfish is one of the largest of the family. It attains a length of more than 2 feet and a 



weight of many pounds. Ah a f 1 fish it is of considerable importance, the flesh being fairly firm and 



of good flavor, and it takes the baited hook freely and possesses some game qualities. It is known to 

 occur from San Diego to Boca de Quadra and Loring in southeast Alaska in moderate depths. 



84. Sebastodes rosaceus iGirardi. Oramic-rrtl Rockfish. 



Two specimens (no. 2822 and 2823), 5.2 and 9 inches long, seined near Marrowstone Point, June 29, 

 and 1 example (paper tag no. 105), 9.5 inches long, collected by the Albatross al station 2887, off the 

 coast of Oregon, October 19, 1888. 



The membranes of the dorsal and anal fins are deeply incised, being very different from all other 

 species with which we are acquainted. In the soft dorsal and anal the interradial membranes do not 

 reach more than two-fifths of the length of the rays. We have compared our specimens with 9 others 

 from Santa Barbara and find thai .-one- of the latter show tie- same structure, though the majority Bhow 

 little or no incision of those membranes. 



This species reaches a length of a fool or more and is a good pan Iish. Its range extends limii San 

 Diego to Puget Sound. 



85. Sebastodes rupestris (Gilbert I. 



The collection contains 3 specimens 4.75 to (>' inches long I nos. 2906 s ' from station 425;:. in Stephens 

 Passage, and one 6 inches long from station 42:'. 1 in Behm (anal. The last specimen has 14 Bpines in 

 the dorsal, but in all other respects it agrees with the other specimens. Maxillary in all three specimens 

 reaches to posterior margin of pupil; gillrakers 9 4-lfi ( 4-4 tubercles), more numerous than usually given 

 in descriptions. 



Comparison of our specimens with the types shows no imporant differences. The black on the tins 

 in the types has faded, while in ours it is still very distinct. < >urs also have a large dark opercular spot 

 not mentioned in the description of t fie types. We nave also compared our specimens with the types of 

 Seba&tichthys aurora and find them to agree fully. We are mmble to discover any characters by means 

 of which they can lie distinguished, and an' therefore compelled to unite these two nominal species. 

 5. rupestris as here understood ranges from the Santa Barbara Islands northward to Southeast Alaska 

 (Stephens Passage and Behm Canal).

86. Sebastodes dalli (Eigenmann & Beeson). 



A single specimen (no. 2820), 8 inches long, taken on hook at 1 nion Bay, June 23. It appeal- to 

 agree with 5. dalli, except that the- maxillary is closely scaled on the posterior half. 



Gillrakers 7+18, longest 2 in eye, the first 5 on ih short limb blunt and rough-tubercular, the last 

 8 on the long arm similar. Scales til or 62, about 15 in oblique series along lower portion of side; head 

 3; depth 3: eye I 5; snout 4.5; interorbital a little less than eye. 



Dorsal 13; anal 6; dorsal spines L.75 in head; nasal, postocular, pr :ular, tympanic, and parietal 



spines present; coronal spine on right side and nuchal -inn.- on right side present; a small humeral spine 

 present; preorbital with one broad spine. Mandible naked; maxillary closely sealed on posterior half. 



The only specimens previously known are the type (from San Francisco) and another from Vancouver 

 Island. 



87. Sebastodes caurinus I Richardson). 



We have 15 specimens 2 to 5.5 inches long collected by Osgood and Heller at Queen Charlotte 

 Island, July, 1900; one specimen l no. 1820), 10.5 inches long, collected in 1895 in Klemtoo Harbor; one 

 11.5 inches long obtained by the Albatross at Sitka in 1S9H; one 9.5 inches long by Luttrell al Sitka; one 

 20 inches long collected at station 34 19 off Washington; 19 specimens collected near Seattle in 1903 by
