55. PARALABRAX HUMERALIS ( Cuvier and Valenciennes). 



Nuinort)ns specimens were collected at Callao, Peru, from 1(» to 85 

 cm. in length. TIk^ young of 1(» or 12 cm. in length have 7 cross bars, 

 composed of small dark-l)ro\vn spots scattered over a dusky ground 

 color. These are regular in form and position on lower half of sides, 

 Init on middle of sides a longitudinal band more or less interrui)ts them, 

 and their upper ends are more indefinite and do not always coincide in 

 position with their lower ends. A dusky ])and runs downward from 

 eye o])liqiiel3^ across cheek. The soft dorsal, anal, and caudal haxc 

 round ])rown spots scattered over them. On specimens 15 cm. in 

 length all of these markings are indistinct, and on large specimens 

 they are altogether lost. A white spot is usually present on the hack, 

 between the lateral line and base of dorsal, opposite the notch between 

 dorsals, both in young and adult examples.
