are larger than about half the area of the orbit; most are smaller. 

 The spots are darkest along- the midline of the side and largest in the 

 area between and under the posterior half of the spinous and anterior 

 half of the soft dorsal fin. From this area the spots decrease in size 

 and increase in number anteriorly to the pectoral axil, where they 

 are smallest. The spots decrease in size and number posteriorly to 

 the caudal peduncle. The spots also decrease in size and intensity 

 both dorsally and ventrally to the dorsal and ventral body contours. 

 The darkest spots cluster in about five areas on the body, which may 

 indicate that the spots are derived from a bandlike pattern (evident 

 in specimens from other collections). The venter is pale. 



The side of the head is variably dusky with an irregular, slender, 

 somewhat vertical dark stripe posterior to the orbit, and separated 

 from the orbit by a distance half the orbital diameter. A faint 

 second stripe extends from the ventral midmargin of the orbit to the 

 upper lip. The top of the head is not noticeably marked. The 

 underside of the head in males varies from almost uniformly dusky to 

 having a pattern of dusky chevrons separated by pale stripes; the 

 underside of the head infrequently has a pattern of numerous dusky 

 spots. In females the underside of the head is marked as in males 

 but the pale stripes are more obvious and the dusky chevrons are 

 intruded by small pale spots. The upper lip is faintly dusky. 



The spinous dorsal fin of males is dusky with two or three rows of 

 pale spots coursing through it; that of females marked with diffuse 

 dusky and pale spots, a pattern which can be derived from that of the 

 males. The soft dorsal fin of both sexes bears dusky stripes coursing
