418 SNODGRASS AND HELLER 



Gill from Cape San Lucas specimens. A specimen in the Stanford 

 University museum from San Luis Gonzales Bay shows indications 

 of the dark markings of the Galapagos specimens. In the Galapagos 

 specimens the body color is light yellowish-brown, the tip of the lower 

 jaw, snout, interorbital and median line of the back dark-brown, nape 

 and occiput spotted with dark brown ; sides from pectoral to caudal 

 with a broad band, 3 scales wide, of dusky-brown following the 

 lateral line ; a lighter brown band beginning at anal and extending on 

 each side of fin to caudal ; these lateral bands separated by light stripes 

 of the body-color about one and one half scales wide ; sides of head 

 above the level of opercle brown-spotted ; cheek with a golden spot 

 below the eye; caudal, pectoral and dorsal fins dusky spotted. Scales 

 146 to 498. Some of the specimens, presumably males, have the 

 pectorals greatly elongated extending much past the curve of the lateral 

 line to about the middle of the body.
