THE SHORE FISHES OF PERU 323 



gill rakers at angle scarcely as long as pupil, 12 on lower and 5 on 

 upper limb of first arch; lateral line strongly arched, becoming hori- 

 zontal over posterior rays of anal; scales very small, firm, strongly 

 ctenoid, extending forward on interorbital and on all the vertical fins, 

 exclusive of the spinous part of dorsal, and slightly on base of pectoral; 

 dorsal fin continuous, the fifth or sixth spine highest, 2.1 to 3.2 in 

 head, soft part much higher, the longest rays nearly twice the length 

 of the longest spines, its margin nearly straight, the lobe anteriorly 

 rounded; caudal slightly concave, the upper lobe slightly the longer; 

 anal fin similar to soft part of dorsal, though somewhat shorter, the 

 spines moderately well developed, the second longest, 3.25 to 5.8 in 

 head; ventral inserted behind base of pectoral, rather broad, the second 

 and third rays longest, 1.1 to 1.5 in head; pectoral broadly rounded, 

 not quite reaching tip of ventral, 1.25 to 1.3 in head, 3.6 to 4.0 in 

 length. 



Color of a specimen 210 mm. long pale yellow, with six very dark 

 (nearly black) bars, nearly or quite encircling the body; the first across 

 eye, forming a V with its fellow at nape; the second broader than the 

 first, crossing back in front of dorsal, and bases of pectoral and ventral; 

 the third still broader, lying under middle of spinous part of dorsal; 

 the fourth of about same width as the third, crossing body between 

 anterior half of soft part of dorsal and anterior half of anal ; the fifth on 

 anterior part of caudal peduncle, and extending on and covering most 

 of the soft portions of the dorsal and anal fins ; the last one at base of 

 caudal; the pale interspaces of about the sam^e width as the dark bars, 

 these marbled with dark areas; a jet-black V at nape, with limbs ex- 

 tending downward and backward, expanded distally; dorsal and anal 

 fins of about same color as the dark bars; caudal dark, with pale mark- 

 ings; basal half of ventral pale, distal half black; pectoral dark at base, 

 the rest of fin olivaceous, with dark spots. In the largest specimen, 

 500 mm. long, the bars have become rather obscure and the pale 

 "ground color" has become dark and is spotted with white. These 

 white or pale spots have spread sparingly into the "dark bars." The 

 fins are rather dark, especially the ventrals, and all, exclusive of the 

 ventrals, are spotted with white. The margin of the opercle is very 

 dark. The juveniles, 33 and 40 mm. long, are plain yellowish, with 

 the dark bars very definite. 



Four specimens, 144 to 500 mm. (112 to 380 mm. to base of caudal) 

 long, and two juveniles, 33 and 40 mm. (25 and 30 mm. to base of 

 caudal) long, are included in the Peruvian collections studied. Four of 

 these were collected by the Mission, one in Lobos de Tierra Bay, one 

 in Lobos de Afuera Bay, one in Paita Harbor, and a juvenile in 

 Samanco Bay, off Mount Campaiia. The others, an adult and q. 

 juvenile, were obtained by R. E. Cpker at Lobos de Afuera.
