less than orbit. Head compressed; eye large, orbit 3^ in head; inter- 

 ovbital space evenly convex, 4^ in head; cranial ridges nearly obsolete; 

 parietal ridges very low bnt broad, brown; nasal spines small, far apart; 

 preocular rather strong, triangular; snpraocnlar and postocnlar usually 

 present, very minute; tympanic and parietal spines sometimes present. 

 Mouth moderate, oblique; maxillary very little more than 3 in head, 

 nearly reaching vertical from center of pupil, its posterior end very wide, 

 2 in orbit; lower jaw much projecting, with a prominent, forwardly 

 directed, symphyseal knob, which enters the profile; narrow bands of 

 teeth on jaws, vomer, and palatines; preorbital rather narrow, its lower 

 margin lobate, with sometimes a small spine; preopercular spines flat, 

 sharp, nearly equidistant, all directed backward, the second longest, 

 fourth and filth minute; opercular spines flat, sharp, somewhat diverging, 

 the u])per considerably larger; spines on shoulder weak ; gill rakers 29 

 on anterior limb, long, slender, very little more than 2 in orbit. Dorsal 

 spines slender, low, the fourth longest, 28 in head, the twelfth f as long 

 as longest; soft rays equal longest spines; only a slight notch between 

 the 2 dorsals ; caudal lunate. If in head; second anal spine stronger and 

 considerably longer than third, longer than soft rays, longer than longest 

 dorsal spine, very little more than 2 in head; pectorals reaching beyond 

 veutrals, bnt not to vent, a little less than head, 3.V in length of body, 

 their base narrow, equal to orbit, the lower rays not thickened. Scales 

 rather small, everywhere strongly ctenoid; accessory scales not very 

 numerous; preorbital, snout, maxillaries, mandible, and branchiostegal 

 rays scaled; all the fin rays more or less scaly. Bones of skull thin, 

 cranial ridges nearly obsolete, parietal bones meeting; interorbital spare 

 somewhat convex, 3^ in base of skull; a slight depression on each side of 

 a sharp narrow median ridge, and another just within each supraocular 

 ridge; ventral process of basisphenoid rudimentary; mesethmoid pro- 

 cesses compressed, not elevated; base of skull very strongly curved. 

 Color much as in Schasiodes oralis; dark olivaceous, tinged with reddish, 

 especially below ; a large irregular dark blotch under soft dorsal, crossing 

 lateral line; a smaller one on lateral line below posterior part of spinous 

 dorsal ; top of head and anterior part of back to about ninth dorsal spine 

 nearly uniformly dark to below lateral line; 2 indefinite dark bands from 

 behind orbit across preopercle nnd opercle; lips bhick; doi'sal fin oliva- 

 ceous; spinous dorsal dark-edged; soft dorsal darker at base; caudal and 

 pectorals olivaceous; axils dark; ventrals yellowish; anal pale; no small 

 round black spots anywhere; peritoneum black. Length of type speci- 

 men 7f inches. Monterey Bay, California; not rare; formerly confounded 

 with the young of S. oralis; more common than -the latter. (^Named for 

 Mr. Timothy Hopkins, founder of the Hopkins Seaside Laboratory.)
