posterior border of orbit ; occipital ridges spineless, temporal ridge broken 

 into 2 or 3 tubercles, sometimes ending in a small suprascapular spine. 

 Cheeks nearly vertical, the suborbital ridge but sslightly developed; usu- 

 ally a spine at lower l)order of orbit, 3 or 4 small ones on inferior border 

 of preorbital, a moderate one on suborbital, a rather large one, and beneath 

 it, a smaller one on the preopercle ; 3 or 4 moderately developed plates, or as 

 many smaller ones with numerous minute plates or prickles, on cheek 

 below ridge;, nasal spines minute, converging behind maxillary pedicles; 

 median rostral plate absent. Mouth oblique, a little less so than in 0. 

 dodecaedron, the lower jaw protruding; maxillary reaches to opposite front 

 of pupil. Teeth present on jaws, few and small on vomer, few or none on 

 palatines. One barbel at tip of each maxillary. Dorsals long, moderately 

 separated; anal long, beginning under posterior end of first dorsal; pecto- 

 rals 4^ in length of body, their width at base 3 in their length, are rounded, 

 the lowermost rays ra])idly shortening ; ventrals of female a little less than 

 2 in pectorals, those of male much longer, reaching beyond front of anal, 

 longer than pectorals; the membrane broad. Caudal 3 times as long as 

 wide at base. Color dark grayish or brownish, pale below; the young 

 Avith distinct cross bars, a broad one in front of lirst dorsal, 1 under the 

 front end and 1 behind middle of first dorsal, 1 between dorsals, 1 under 

 second dorsal, and 2 on peduncle; bars indistinct in adults ; dorsals dusky, 

 faintly barred with darker, caudal dark ; anal dark on membrane, white- 

 edged (dark only on posterior end in young, as in 0. dodecaedron) ; pecto- 

 rals washed with orange, 2 dark blotches near base, the terminal part 

 with 2 (sometimes confluent) or 1 large dark patch (these patches in the 

 young appearing as partially confluent bars, more like O. dodecaedron) ; 

 ventrals of female pale, of male bright orange yellow, with n large black 

 spot inside of first ray and 2 small ones at tiji. Length 8 inches. Coast 

 of California and Oregon, south to 8an Francisco, in 11 to 36 fathoms.
