sheath on base of soft part of dorsal and anal, extendmg somewhat 

 on bases of caudal, ventral, and pectoral, six complete rows between 

 lateral line and first dorsal spine, five oblique series on cheek; spinous 

 part of dorsal notably longer than soft part, third or fourth dorsal 

 spine longest, 2.4, 1.8, 2.3 in head; caudal rather deeply forked, the 

 lobes pointed, the upper one longest; anal spines moderately strong, 

 the second a little longer than the third, though not reaching beyond 

 its tip if deflexed, 2,6, 2.8, 3.4, the soft part similar to that of dorsal, 

 though somewhat lower, coterminal with it; ventral mserted a little 

 behind base of pectoral, with a moderately strong spine contained 

 2.0, 1.8, 2.3 in head; pectoral long, especially in adult, equal to or a 

 little shorter than head in small specimens, longer than head in adult, 

 3.5, 3.1, 2.8 in length. 



Color grayish above, silvery below; side with seven dark cross bars, 

 distinct in small specimens, less so in the largest one (disappearing 

 with age according to Panama specimens), the first and broadest bar 

 extending from nape across eye and cheek, second bar somewhat in 

 front of dorsal, and extending down on side behind base of pectoral, 

 next four all under base of dorsal and all of about equal width and 

 equally spaced; last bar on caudal peduncle; opercle slightly blotched 

 with dusky; pectoral with a small dark spot at base of upper ray, the 

 fin otherwise plain translucent; other fins with dark spots and blotches, 

 forming indefinite bars on the caudal (these fins becoming quite plain 

 in large specimens from Panama). 



This species, which is new to Peru, is described here from three 

 specimens, respectively 30, 45, and 180 mm. (23, 35, and 135 mm. to 

 base of caudal) long, collected by the Mission at Lobos de Tierra 

 Island and in Independencia Bay at Lagunilla. The proportions 

 and enumerations are given m order of size, beginning with the small- 

 est one. The specimens seem to agree with examples from Panama 

 Bay and the Gulf of California, with which they were compared. 

 The species probably is not numerous, though apparently known to 

 local fishermen, as the collectors furnished a name for the largest 

 specimen taken at Lobos de Tierra Island. 



Range. — Gulf of California to Peru. Previously reported from only 

 as far south as Guayaquil, Ecuador.
