THE FISHES OF ALASKA. 



289 



Head 2.9; depth 2.9; eye 4; snout 4.1; maxillary 2; mandible 1.9; interorbital 5.25; dorsal xm, 

 12; anal m, 6: gillrakers 8+19, rather stout, longest 2.75 in eye; scales 57, pores 48; longest dorsal 

 spine 1.8 in head: longest dorsal rays 2.1 in head. In other specimens the gillrakers were 10+ 21 or 

 10+19. 



Body short, stout, and deep; mouth slightly oblique, lower jaw net projecting, maxillary nearly 

 reaching posterior border of orbit; mandible and maxillary not scaled; nasal, preocular, postocular, tym- 

 panic and parietal spines present; nuchal, coronal, and supraocular spines absent; preorbital with 2 

 broad, low points, not spine-like. 



This species is known to range from Monterey to Sitka in lather deep water, being abundant north- 

 ward. It reaches a length of about 2 feet. It was also recorded from Sitka by I!ean (1882) as 

 ■s'< bastichthys maliger. 



89. Sebastodes nebulosus | Ayres). 



A small specimen (no. 112), 2.5 incites long, from station 4204. off Fort Rupert. We have also 2 

 others, 11 and 12 incites long, taken by Mr. II. <'. Fassett at Klawak in 1905. Bean (1884) records it 

 from Mary Island. The following measurements an- taken from the small example from station 4204: 



Head 2.75; depth 3.6; eye 2.9; dorsal xm. L3; anal in. 6; scales 15 t.. 47. about 42 pores; gill- 

 rakers long and slender; nasal, preocular, postocular, tympanic, and parietal spines present. The color, 



however, does not exactly agree with that L'i\en for this species. < tin specimen in alcohol is clayey 

 white, mottled with large, irregular brown blotches, about 1 along side above lateral line. 2 or ;{ 

 immediately below it, and :i along lower part of side, spinous and soft dorsals similarly mottled. 



90. Sebastodes nigrocinctus i Ayres i. Black-banded Rockfish. 



Two specimens, 13 and H inches long, taken by Mr. H. ('. Fassett at Klawak in 1905, and one 

 specimen (no. 2863), 12 inches long, taken by Mr. Chamberlain on hook and line at Xaha Hay. Loring, 

 July 7, 1903, where he states that the species is common. This specimen gives the following meas- 

 urements: 



Fig. 39.— Sebastodes nigrocinctus (Ayres t. 



Head 2.65; depth 2.67; eye 4; dorsal xm, 14; anal m, 7; scales 52; pores 44; snout 4.5; gillrakers 

 9 + 21, stiff, rough, clavate, the longest 3.5 in eye, the terminal ones of each arm reduced to tubercles. 

 It differs from typical examples in the following respects: There is a small supraocular spine on the 

 left side; the mandible is pretty well covered with very minute, thin cycloid scales; the nuchal spines 

 coalesce with the parietal. 



< 'olor in life: Body blood red; cheek with a black stripe downward from front of eye to lower edge 

 of cheek; another from eye backward and downward to branchiostegals; a large black blotch on upper
