ridges low and not much crested, but quite discernible; occipital 
ridge long, about as high as in S. nebulosus, irregularly serrated, and 
not ending in any very distinct spine; the upper two preopercular 
spines rather sharp, the next two flattened and serrated on the end, 
the anterior one blunt; opercular spines flat ; humeral and scapular 
small. Second and third anal spines about equal in height and size. 
Spinous dorsal higher than the soft portion. Posterior margin of 
the caudal nearly even. Colour nearly uniform light crimson, lighter 
beneath. 
This is the species described by me in 1854 (Joc. cit.), but is not 
the one to which the name is referred by Girard (P. R. Rep. x. 
p: 78) as asynonym of S. rosaceus. The two have little close re- 
semblance, except in colour. The points of difference will be given 
when speaking of Sebastodes rosaceus. 
S. ruber is not at all rare. It grows to decidedly a greater size 
than any of the other species, reaching occasionally a weight of 
twenty-five pounds, and, as the fishermen assert, even greater still, 
while those of from ten to twelve pounds are quite common.

Sebastichthys ocellatus, Gill (loc. cit.). 
Upper surface of the head quite strongly ridged. Nasal and an- 
terior supraorbital spines sharp, quite prominent; posterior supra- 
orbital forming a crest, which ends in commonly two prominent 
sharp spines ; intraorbital fossa well marked, with two intraorbital 
ridges ; postorbital spine appearing like a continuation of the poste- 
rior supraorbital, prominent, very sharp ; occipital ridge somewhat
