and prepectoral area with cycloid scales, much less than | the size of 

 those on sides; scales elsewhere ctenoid; 10 or 11 scales in an oblique 

 series between lateral line and the one above it; uppermost lateral line 

 forking on the nape, the branches running to opposite the middle of the 

 second dorsal; the second lateral line to upper edge of tail; the third to 

 middle of tail; the unbrauched fourth to a little beyond the middle of 

 anal; the fifth to lower edge of tail; the fourth beginning near the lower 

 edge of the pectorals and undulating opposite the ventrals, the lowermost 

 on & each side joining just in front of the vent, and proceeding on the 

 median line to the middle of the breast. Pectorals and ventrals large; 

 caudal slightly emarginate; membranes of soft dorsal and caudal densely 

 scaled for more than height of fin. Two pairs of cutaneous flaps on 

 head, the usual supraocular pair, less than \ diameter of pupil, and a 

 much smaller occipital pair which is present in no other species; dorsal 

 high, deeply notched; caudal emarginate when closed, slightly convex 

 when Avidely spread. Adults brightly colored, the males with large sky- 

 blue spots, the females with smaller red or orange spots. Young sometimes 

 plain brown, with dark plain humeral spot. Males clear brownish olive 

 of varying shade, often tinged with bluish or coppery and vaguely blotched, 

 often with small blue spots ; head and anterior part of body with rather 

 large sky-blue spots, each surrounded by a rusty ring, these smaller and 

 more numerous on the top of the head; lips with bluish spots; upper fins 

 brown, mottled; ventrals and anal dusky bluish; pectorals dark, both 

 ravs and membranes crossed by sharply defined whitish reticulations, so 

 that the fins appear to be profusely spotted with white. Females brownish , 

 somewhat tinged with reddish, closely covered with round spots of a red- 

 dish brown; these spots usually quite small and uniform over the whole 

 back and sides ; dorsal fin spotted on the scaly part, the fins otherwise 

 plain reddish or bluish, the ventrals usually dusky ; pectorals light orange, 

 without markings. Other females ("maculoseriatus") have the ground color 

 slaty blue, with rows of round orange spots considerably larger than usual, 

 and becoming vermiculations on the head; dorsal fin orange, clouded at 

 base with blue; soft dorsal edged with bluish; pectorals plain orange; 

 belly white. These vary into the ordinary type. Both types were found in 

 abundance at Sitka. Length 18 inches. North Pacific; abundant from 

 Point Concepcion to Kadiak Island, Alaska ; especially about San Fran- 

 cisco, a common food-fish; the sexes very unlike, the females varying much 

 in color; the males very uniform, (dena, ten; ypajujutf, line.)
