 yellowish, darker above (doubtless bright red in life) ; 4 short faint cross 

 bands on upper part of sides, 1 under second, third, and fourth dorsal 

 Bxiines, a second under sixth and seventh sj)iues, a third under ninth, tenth, 

 and eleventh spines, and the fourth under the soft dorsal ; a black spot on 

 upper part of opercle; membrane of spinous dorsal black-edged; dorsals 

 and pectorals a little dusky, fins otherwise pale; inside of mouth a little 

 dusky at the sides and in front of tongue; inside of gill cavities dusky in 

 front of pscudobrauohia- ; peritoueuia dark brown. Coast of Alaska ; only 

 the type, 6^ inches long, known. (Named for Mr. Frank Cramer, of Leland 

 Stanford Jr. University, in recognition of his work on the genus 

 Sebmtodcs.)

D, XII-I, 13; A. Ill, 7. Head 2,'^ to 3; body slender, the depth 3| to 3| 

 in length. Mandible with a moderate sympliyseal knob, which projects 

 to enter the profile. Maxillary scarcely reaching vertical from middle of 

 pupil, 2f to 2?^ in head. Eye averaging smaller than in S. saxicola, 3i to 

 31 in head (rarely 3 in head). Interorbital space of moderate width, flat, 

 with a slight median lengthwise groove bounded by a pair of low rounded 

 ridges, the groove and ridges sometimes not evident. Preocular, supra- 

 ocular, and occipital ridges low, but sharp and evident, terminating in 

 strong though slender spines. Nasal, pi-eoculai-, postocular, tympanic, and 

 occipital spines present, the preocular the strongest, directed outward 

 and backward so as to project over the orbit. Parietals not in contact; 

 preorbital narrow, with 2 triangular or rounded lobes, with or without 

 slight spinous tips. Preopercular spines with compressed triangular base, 

 the upper 2 usually nearest together, directed backward or slightly 

 upward, the others backward and downward ; a subopercular and an inter- 

 opercular spine closely approximated; 3 humeral spines. Gill rakers 

 long, slender, very numerous, developed as movable rakers to the extreme 

 anterior end of the arch; 10 or 11 gill rakers on vertical limb of anterior 

 arcli, 27 on horizontal limb, the longest slightly less than diameter of eye. 

 Fifth dorsal spine highest, 2^ to 21 in head, longer than the soft rays, the 

 membranes between spines not deeply incised; the notch between dorsals 

 rather shallow, the twelfth spine f to 4 length of thirteenth ; caudal emar- 

 ginate; second anal spine strong, longer than third, usually not reach- 

 ing tips of soft rays when fin is declined; length of second spine I 

 that of head; ventrals usually reaching to or beyond vent; the pectorals 

 varying from slightly behind A'ent to slightly behind origin of anal. 

 Scales on breast cycloid or weakly ctenoid, elsewhere on body rough 

 ctenoid; head completely scaled, the scales on top of head and on cheeks 

 ctenoid, those on snout, maxillary, mandible, and branchiostegal rays 

 much reduced in size and smooth, 46 to 48 tubes in the lateral line; about 

 95 vertical transverse series above the lateral line, each series under the
