green, becoming lighter on sides, leaving a dark postocular line extending from eye to preopercular 
spine and a dark spot on lower margin of preopercle, everywhere very finely marked with white and 
bine; a white spot with a brown center just in front of first dorsal; throat and belly a very light 
bluish-green, shading into a faint yellow behind pectorals, and a brownish-green on each side of 
anal; all the fins, except ventrals, light brownish-green barred with dark brown; caudal light 
reddish-brown, anal and tip of pectorals tinged with pinkish. A young example is lighter and more 
brilliantly colored. This species is most closely allied to Dialarchus snyderi, from which it differs in 
presence of a third preopercular spine, greater depth and comparative length of head, larger eye and 
nasal spines, and arrangement of cirri. Many specimens taken at Monterey Bay, but not recorded 
from any other locality. The most brilliantly colored of the tide-pool fishes, inhabiting only deep 
pools rich in plant life.

Ground color brown, tinged with olive and broken by many white spots below, lower row shading 
into yellow of ventral side, leaving a scalloped margin ; body crossed by several lavender bands, the 
extent of which is extremely variable, depending on color of algae; usually a broad baud extending 
front just behind eye’s to the middle of first dorsal, and reaching edge of opercle on sides, with two or 
three less distinct bands behind this; a spot of same color at end of soft dorsal, continued on the two 
sides; another more distinct spot on base of caudal at end of lateral line; three or four smaller spots 
along lateral line which embrace a corresponding number of broad lamellaj-skaped cirri, much larger 
than the rest; a blotch of pink at base of pectorals, with very fine vermiculations of same color on 
soft dorsal; spinous dorsal reddish ; soft dorsal brown, shaded with red and irregularly spotted with
