third, first spine below the first soft ray of the dorsal. Ventral reaching 
the vent. Caudal about two thirds as long as the head, truncate. 
Pyloric appendages three. Air bladder large. This species has but 
twenty-four vertebre; the nearest of the known species of Sebastes 
have twenty-six. On the largest specimens there are streamers on scales 
and spines; on the smaller ones the filaments are hardly noticeable, 
if present. 
Apparently rose color in life, brownish red in alcohol, flecked with 
brown below the eye, on the side of the head, along the lateral line, at 
the base of the dorsal, and on the dorsal and the caudal. A darker area 
on the parietal region sometimes has a light centre. Some have three 
larger blotches of brown below the spinous dorsal and two more below 
the soft dorsal above the lateral line. Very small individuals are similar 
to the larger ones in color, but the bunches of teeth are less prominent.
