The general color is pale straw. Five of these have three black spots with 

 white centres on the top of head, one of the spots is behind each eye and one of 

 occiput just before first dorsal; another (the smallest) has the three black dots 

 similarly situated but^without the white centre; another (the largest) has but 

 one black spot, it is on the occiput and lacks the white centre; a short black 

 cross-bar at posterior base of isthmus in front of ventral, another on belly just 

 back of base of ventral; a black dot at base of each soft dorsal ray and two on 

 top of caudal peduncle and two on its lower edge; base of each anal ray black, 

 this color joined to the ray behind it by a black line; a black line across base of 

 caudal. 



The largest of these seven specimens shows traces of dusky bars on caudal 

 fin. 



Jordan and Evermann (loc. cit.) state that the anal is II, 11 (misprinted II, 

 17) in the original description. This could not be verified from the fact that 

 the Type can not be found. The present specimens, if correctly identified, show 

 that the original count was probably correct.
