NC.1484. JAPANESE FLOUNDERS AND SOLES— JORDAN & STA RKS. 233 



Head, 5i to 5f in length to base of caudal; depth, 2i to 2|. Upper 

 eve, 6i to 7i in head. Dorsal, 72 to 76; anal, 63 to 66. Scales from 

 opposite gill opening to caudal, 89 to 96; 15 or 16 on head between 

 upper eye and gill opening. 



Mouth terminal and curved, but the tip of upper jaw scarcel}- 

 hooked. Small teeth in bands on blind side of jaws. Eyes separated 

 by a narrow, scaly interorbital space, less than half the diameter of 

 upper eye. Anterior fourth to two-tifths of upper eye a])ove front of 

 lower eye. 



Upper 3 or 1 rays of pectoral of eyed side produced but not 

 abruptly, the lower outline concave and the length of the rays from 

 the first to the last graduated, its length of the produced rays variable, 

 from li to 2i in head. Ventrals nearly S3Mumetrical and Avell sepa- 

 rated from the anal. Last rays of dorsal and anal reaching to tips of 

 caudal rays, so that the outline is continuous around the caudal. 



Fig. 20.— Zebrias zebrinus. 



Length of last dorsal ray li in head, equal in length to that of anal. 

 Caudal rounded narrowly; its length nine-tenths of that of head. 

 Scales everywhere ctenoid. Pores of lateral line equal in number to 

 series of scales; the lateral line extends onto the head over (> or 7 

 scales. 



Head and body light gray crossed with l)lack bars more or less defi- 

 nitely ai-ranged in pairs. These may be uniform black or a little 

 lighter in the middle, but never conspicuously lighter as in Z. japoni- 

 rus. A bar across gill opening, involving base of pectoral, its pos- 

 terior edge just behind base of pectoral. Behind this are 8 pairs of 

 bars, the posterior one of the last pair much the widest, its posterioi- 

 edge just at or somewhat anterior to base of caudal. Base of caudal 

 rays of the gray body color; the greater part of the caudal, iiu-luding 

 the tips of the dorsal and anal rays, marked with a large round di>ad 

 black spot two-thirds of the length of the head in diameter anil bear- 

 ing several milk-white, clear-cut oblong spots of irregular size, often
