NO. 1351. SCORPJSNOID FISHES OF JAPAN— JORDAN AND STARKS. Ill 



Head 2 1 in length; depth 2|; depth of caudal peduncle 3| in head; 

 eye4|; snout 4; maxillary 2|; interorbital space 4^; height of longest 

 dorsal spine 2|; longest ray 2|; anal spine S^; ray 2-}', length of pec- 

 torals 4 in length; ventrals 5; caudal 4i; D. XIII, 12; A. Ill, 7; 

 pectoral rays 10-8; scales in lateral line 51; pores 16. 



Eye moderate in size; nearer tip of snout than to posterior edge of 

 opercle, a distance ecjual to its diameter. Snout ecjual in length to 

 diameter of eye. Lower jaw projecting; sy mphysial knob scared}' 

 noticeal)le. Maxillar}'^ extending to a vertical through posterior edge 

 of or])it. Bands of teeth on jaws, palatines, and vomer; palatine ])ands 

 as wide as those on lower jaws. Gill-rakers, 6-17; thosci on upper part 

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

 a little convex; interorbital ridges very low, rounded. Head not 

 strongl}' armed, the spines all Ij'ing close to the surface; nasal, pre- 

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

 low, rounded, terminating in small, acute spines; preor))ital with three 

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

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

 Preorbital area, maxillary, lower jaw, and branchiostegals naked; sub- 

 ope rcle and lower and posterior edges of preopercle with cycloid scales; 

 other pa-rts of head with small ctenoid scales; those of the interorbital 

 area extending forward to na.sal spines; breast and belly with cycloid 

 scales; other parts of bod}' with ctenoid scales, the edges of which 

 have minute bristles; most of body with minute accessor}- scales 

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

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

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

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

 interspinous 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. Pectoi-al rounded, the 

 lower eight rays simple. Ventrals pointed when depressed. Edge of 

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

 abl(^ irregular ])lotches on upper ]mrts; fins ])roadly edged with darker 

 color; an indistinct light band on pectoral. 



A number of smaller specimens (co-types No. 6271, Leland Stanford 

 Junior University Museum), from the same locality as the type, are 

 much lighter in color, with small, irregular brown spots scattered 

 over the body. In many individuals the spots arc collected together, 

 forming four or five indistinct lateral bands; all have three or four 

 dark lateral ]>an(ls radiating downward and backward from the orbit. 

 The fins show more or less* dark color, the pectoral and caudal often 

 being distinctly l)arred.
