THE SHORE FISHES OF PERU 231 



prominent canines on anterior part of upper jaw, and a few slightly- 

 enlarged teeth in outer series in lower jaw, those on vomer in an 

 anchor-shaped patch, with a long backward extension, those on 

 palatines and tongue in narrow bands; margin of preopercle serrate, 

 the serrae at angle somewhat enlarged, the margin slightly indented 

 just above angle; gill rakers moderate, those at angle about as long 

 as pupil, 11 more or less developed on lower and 6 on upper limb of 

 first arch; scales strongly ctenoid, rows above lateral line parallel 

 with it, six between it and base of first dorsal spine, those below it 

 horizontal; small scales extending on bases of soft dorsal, anal, and 

 caudal fins; dorsal fin scarcely notched, the fourth spine longest,though 

 scarcely exceeding the fifth and sixth in length, 2.4 in head; caudal 

 moderately concave; anal spines strong, the second stronger but 

 scarcely reaching tip of third if depressed, 2.2, 3.1 in head; ventral 

 inserted directly under base of pectoral, reaching beyond vent, with 

 a rather strong spine contained 2.4, 2.7 in head; pectoral rather 

 broad, reaching scarcely as far back as ventral, 1.35, 1.4 in head, 3.5, 3.8 

 in length. 



Color grayish brown above; silvery gray below; upper part of side 

 with obscure dark crossbars; an obscure dark stripe extending from 

 snout through eye to shoulder; rows of scales obscurely marked with 

 dark streaks; fins mostly plain translucent, the base of dorsal with 

 suggestions of dark spots; base of pectoral with a dark band. 



The description is based on two small specimens, 56 and 57 mm. 

 (44 and 44 mm. to base of caudal) long, seined by the Mission in 

 Lobos de Afuera Bay. These specimens were compared with some 

 of about equal length and larger ones from Panama Bay, with which 

 they agree almost perfectly. In large specimens the snout becomes 

 proportionately longer and more pointed, being contained 2.5 to 2.75 

 in the head. The pectoral fin, too, becomes proportionately longer, 

 being contained 1.15 to 1.2 in head, and 3.2 to 3.4 in length. The 

 larger specimens do not have dark crossbars, nor the dark band 

 through the eye, but have a narrow dark line (blue in life) below the 

 eye. 



Range. — Baja California to northern Peru, and the Galapagos 

 Islands. Previously recorded from the coast from only as far south 

 as Guayaquil, Ecuador.
