latter 5| in head, longest ray 3 in head; pectorals reaching somewhat 

 beyond ventrals. Top of head and back chiefly black, lateial line ver- 

 milion, a blackish band just below lateral line, much wider forward 

 extending on sides below the fifth dorsal spine; a large opercular spot, a 

 broad band downward and backward from eye, a narrow one across 

 cheek below eye, lips and tip of lower jaw chiefly black, rest of head and 

 sides chieily vermilion; anal and ventrals vermilion, pectorals and caudal 

 blackish, dorsal nearly black, axils dusky. Peritoneum, black. Length 

 24 inches. San Diego; not seen by us. (Eigenmann & Eigenmann.)

Head 2; depth 34. D. XIII, 14; A. Ill, 7; scales 86 or 87, 51 tubes. 

 Body elongate, compressed, its greatest width ^ length of head; caudal 

 peduncle short, its least depth of its length from end of soft dorsal to 

 base of middle caudal rays; head similar in shape to that of S.proriger. 

 Cranial ridges almost obsolete, except on the occiput, where the spines 

 are long and depressed, nearly as long as the eye; preocular and supra- 

 ocular spines present; no tympanic spines. Mouth large, the broadly 

 expanded maxillary reaching beyond the middle of the eye; length of the 

 upper jaw (intermaxilla and maxilla) almost | length of head; lower jaw 

 much projecting, its length equaling that of eye and postorbital part of 

 head; upper half of the maxilla covered with very fine scales; the man- 

 dible also has fine scales along its middle and posterior portions; mandible 

 with a well-developed knob at the symphysis; eye f as long as snout, 

 rather more than 4- length of head, and about equal to width of the 

 nearly flat interorbital space; width of preorbital less than - length of 

 eye ; preopercular spines short and sharp, second longest, about as long 

 as the eye, the first, fourth, and fifth very small ; the points of the fourth 

 and fifth directed obliquely downward and backward. Gill rakers mod- 

 erately long and slender, 11 -f- -3, the longest at the angle i as long as the 

 snout or f as long as the eye. Spinous dorsal low, the first spine $- as long 

 as the second, and rather more than f as long as eye; the fourth to the 

 sixth spines longest, rather more than ^ length of head. Membrane of 

 soft dorsal and to some extent that of the spinous dorsal scaly; longest 

 soft ray of dorsal rather shorter than the longest spine; the last soft ray 

 as long as the first spine; first anal spine very short, f as long as the sec- 

 ond, or as long as the eye; the second spine shorter and stouter than 

 the third, equal to the snout in length; the third spine nearly H times as 

 long as the eye; longest soft ray exceeding length of longest dorsal spine 

 and nearly equal to the postorbital part of the head; pectorals shaped 

 very much as in S.proriyer, the lower 4 or 5 rays slightly exserted at the 

 ends, the middle rays longest, slightly longer than the head without the 

 postorbital part; ventrals not extending as far back as the pectorals,
