smaller; dorsal surface of tail with a few very small spinous tubercles, which also form series on caudal 

 rays; iris surromided by a ring of small spines, a mnnbcr of scattereil uncs outside this ring. Lateral 

 line miming in a shallow groove; each pajiilla is inelo.«ed between 2 (laps, with narrow ba.ses and 

 fimbriate margins, the flaps flanked by a ]iair of spines; 3 acce.ssory pai)ill;e of the mandibular series, 

 as in 1). /•riithritiiix, placed on anterior margin of groove opposite interval between lirst and second, 

 fourth and fifth, and bc^tween fifth and sixth papilla' of the regular series. 



Distance from hase of caudal to origin of dorsal half the distance from latter to front of orbit; 

 when declined, the dorsal extends .(i (lie distance from its origin to ba.se of caudal; ba.se of dorsal .12.5 

 length of lieail; origin of anal tin slightly nearer vent than base of <"Uldal; pectoral tin reaching base 

 of subojiercular spine, the short ventrals reaching but hall'-way to its tip.

 on each side the middle of disk, and a tliinl pair above and in front of each gill-opening; a vertical dark 

 shade immediately behind doi-sal fin; a faint dark bar on terminal jiortion of dor.sal and one on 

 caudal; lining membranes of buccal, branchial, and abdnminal cavities all white; Im'c lunnarked.
