Body rather robust, eov^ered with moderate ctenoid scales; lateral 

 line complete or incomplete; mouth moderate, the jaws equal; no ten- 

 tacle on nape; no hook on shoulder girdle; eyelarge; dorsal fin divided 

 into ;3 tins, the lirst of 3 or 4 slender spines, the second of 10 to 24, 

 the soft dorsal of 7 to 15 rays; caudal rounded; anal tin lontr; pectoral 

 long, the lower rays simple and thickened. Small tish of the rock- 

 pools of the Tropics, found in most seas. 



This group has Ijeen divided into four subgenera on minor characters. 

 These may ])e thus defined: 



a. Orbit without filament above. 



6. I^ateral line said to be complete; dorsal rays III-XVII-12; scales rather small, 



40 Tripterygion. 



66. Lateral lines well developed anteriorly, becoming obsolete posteriorly; dorsal 



rays III-X to X V-7 to 10; scales large, about 35 Emieapterygius. 



666. Lateral line almost obsolete; dorsal rays lII-X-7; scales large, rough, about 



35 Enneanecie.'t. 



aa. Orbit with a fleshy filament above. 



c. Lateral line interrupted, weakly developed liehind; dorsal rays IlI-XII to 



X VII-7 to 12; scales large, 33 to 40 Gillias. 



cc. Lateral line said to be complete; dorsal rays V or V1-X\'1I1 to XX-12 to 14; 

 scales small, 40 to 50 (nigripinne. ) 



The two Japanese species belong to the division called GiUia.'^. 



a. Gillias: Orbital tentacle present; lateral line incomplete. 



6. Dorsal IlI-XIV-lO; A. 21; body with dark vertical bands etheosfoma, 1.
