as wide as those on lower jaws. Gill-rakers, 0-17; those on upper part 

 of areh short and blunt; others long and slender. Interorbital space 

 a little e-onvex; interorbital ridges very low, iKDunded. Head not 

 strongly armed, the spines all lying close to the surface; nasal, pre- 

 ocular, postocular, and tympanic spines minute, sharp; occipital ridges 

 low, rounded, terminating in small, acute spines; preorbital with three 

 flat, sharp spines which project downward; preopercle with five flat, 

 rather blunt spines; two opercular and two humeral spines present. 

 Preorbital area, maxillar}", lower jaw, and branchiostegals naked; sub- 

 opercle and lower and posterior edges of preopercle with cvcloid scales; 

 other parts of head with small ctenoid scales; those of the interorbital 

 area extending forward to nasal spines; breast and belly with cycloid 

 scales; other parts of body with ctenoid scales, the edges of which 

 have minute bristles; most of body with minute accessory scales 

 wedged in between the larger ones; spinous dorsal, except a small 

 space on posterior ventral part, naked; other flns with minute scales, 

 which are closely packed at the bases, extending outward along the 

 membranes. Dorsal fins continuous, though having a dividing notch; 

 inter-spinous membranes deeply incised; first and twelfth spines con- 

 tained three and one-third times in length of maxillary; fourth to 

 seventh spines longest; tenth and thirteenth spines of equal length; 

 second and third dorsal rays longest. Anal fin rounded, first spine a 

 little less than one-half the length of second; second and third spines 

 of equal length, the second much stronger. Pectoral rounded, the 

 lower eight ra3\s simple. Ventrals pointed when depressed. Edge of 

 caudal slightly convex. Color, in alcohol, dark, with scarcely notice- 

 able irregular blotches on upper parts; fins broadly edged with darker 

 color; an indistinct light band on pectoral. 



A number of smaller specimens (co-types No. ()274, Leland Stanford 

 Junior Univ. Mus.), from the same locality as the type, are much 

 lighter in color, with small, irregular l)rown ^<pots scattered over the 

 body. In many individuals the spots are collected together, forming 

 four or five indistinct lateral l)ands; all have three or four dark lateral 

 bands radiating downward and backward from the orbit. The fins 

 show more or less dark color, the pectoral and caudal often being 

 distinctly barred.
