no. 2075. FISHES FROM SOUTHERN CALIFORNIA— GILBERT. 



335 



Spinous dorsal low, the spines rather strong, the membranes not 

 deeply incised. Second anal spine decidedly longer and stronger 

 than the third, equal in length to the first soft ray, its length equaling 

 distance from tip of snout to posterior margin of orbit. Caudal 

 gently concave. Pectoral rather short, barely attaining vertical from 

 vent, the longest ray 1.2 in length of head; 17 rays are present, the 

 lower 8 thickened and simple, the others slender, all but the upper- 

 most divided. 



Color in spirits generally light, the opercles, breast, and ventral 

 region white. Rather faint dark bars along upper profile, one on 

 occiput, one at beginning of spinous dorsal, one at its middle and 

 one near its end, two under second dorsal, and one on back of caudal 

 peduncle ; a narrow brownish-red streak or line runs below the lateral 

 line and nearly parallel with it to opposite end of anal fin. The dark 

 blotches along base of dorsals extend on the basal portions of these 

 fins ; membranes of caudal fin with a few dark streaks ; fins otherwise 

 unmarked. Mouth and gill cavity white. Peritoneum black.

A single paratype, 105 mm. long, from station 4518, Monterey Bay, 

 depth 66 to 140 fathoms. 



I take pleasure in naming this species for Prof. C. B. Wilson, in 

 recognition of his valuable contributions to our knowledge of the 

 crustacean parasites of fishes.
