Young, 18 to 34 mm.: Background color light tan, with a dark 

 brown band about width of pupil extending from upper end of gill 

 opening to caudal fin base, then fading posteriorly; sometimes black 

 band with roundish black spots, from which vertical bars develop; 

 black spot over pectoral base usually more intense than other spots; 

 upper part of spiny dorsal clear, basal two-thirds dusky. 



Young and half grown, 25 to 50 mm.: First trace of round white 

 spots on throat observed at 25 mm. standard length, these white 

 spots occur in largest adults; black band replaced by 10 to 12 dark 

 brown bars on sides; at a length of 35 mm. one specimen had the black 

 band and vertical dark brown bars; usually the light spots become 

 distinct at 36 to 40 mm. and from 42 to 45 mm. occur on sides of 

 head, at 36 to 55 mm. the vertical bars are very distinct; usually 

 the pectoral spot is distinct at lengths up to 40 mm.; at 45 or 46 mm. 

 the convoluted dermal pads on first two anal spines begin to develop 

 and are grayish in color; from 50 to 60 mm. this stage overlaps with 

 the next. 



Over 55 mm.: Background color very dark or blackish; vertical 

 bars obscured or absent; white spots, size of pupil occur on throat, 

 breast, side of head, behind pectoral base; sometimes these markings 

 are marbled; adult males, beginning at about 75 mm., have tiny 

 silvery white spots or short lines on the sides; pel vies dark, distal 

 edge of spiny dorsal pale; dorsal part of caudal fin pale; first dorsal 

 spine of adult males elongate, white; distal part of caudal pale or clear. 



Ecology. — This species was commonly taken in the Lithothamnium 

 ridge area in the surf or where wave action was strong. 



Remarks. — Salarias (Cirripectes) polyzona Bleeker is referred as 

 a synonym of C. sebae since it represents the barred stage of coloration. 

 C. variolosus and C. sebae occur together in the collections made at 

 Bikini; they are distinguished by the 33 to 42 cirri in sebae and 29 

 to 37 in variolosus and by the differences in color pattern — chiefly 

 the lack of vertical bars, white spots, and black band in variolosus.
