It seems doubtful whether the true P. insidiator is found in Japan. The eyes of the figure 
before us, as well as those of the so-called P. insidiator in the Faun. Jap., are much smaller 
than those of the true kind, besides other differences. The range, from the Red sea to Japan, 
seems too great for such a delicate fish. It will probably be found that Schlegel’s species is a 
new one. 3

The characters necessary to determine the position of these two Sebastes are not sufficiently 
distinct in the drawings, which are no doubt quite correct as to color. They may be different 
sexes of S. marmoratus, though the first one, in its number of fin rays, seems to agree with 
the S. variabilis of Pallas, which however has no spines over the eyes. The second one seems 
to correspond in its number of fin rays and colors with the S. albofasciatus of Lacépéde, Cuv. 
Val. IV. 344, which is supposed by Schlegel to be only a variety of the marmoratus, 
The colors of figure 1 are as follows: Of a general dull carmine, with broad cloud-like spaces 
of bluish dusky, and blotches of dusky brown on the sides and abdomen. Head of the same 
ground color, with smaller blotches of dusky. Lower part of opercles lighter, with dots and 
bars of brown. Irides red and brown. Dorsals dull brownish carmine, with numerous small 
spots of brown on the spinous portion ; the spots on the soft portion being arranged in four series 
parallel to the back. Caudal brown at the base, ending with orange, the rays annulated with 
brown in four concentric series like spinous dorsal with tinges of orange. Pectoralslight. Anal 
orange, brown at base; the rays annulated in three series with brown. Ventrals dull reddish. 
The second figure differs considerably from the first in color, and somewhat in its form and 
fin rays, enough probably to constitute a different species, were it possible to compare actual 
specimens. The drawings no doubt represent large fish, though the notes do not give the size 
of life. 
This last figure shows a fish of a general vermilion red color, blackish along the back of 
body and head. The head with irregular bars or blotches of dark dusky. Irides, red and 
yellow. Body marbled with indistinct blotches of dusky, the red ground color being varied with 
tinges of yellow. First dorsal blood red with a few spots of dusky on membrane. Second
