 bone large, oblong, conspicuous, and silvery. Mouth rather small, hor- 

 izontal, the lower jaw included, the edge of the premaxillary below the 

 level of the eye, the maxillary not reaching to the vertical from the

 murred much as in C. amblops, the tip of the snout thickened. forming a 

 -,<>rt of pad. Lateral line decurved. iiows of scales along the back 

 converging behind the dorsal where the upper scries run out, as in 

 Minniliifi cornutus. Fins rather higher and more falcate than in G. 

 biyuttatux. The dorsal fill inserted well forward, over ventrals. Pec- 

 toral fins pointed, not reaching ventrals, ventrals not reaching vent. 

 Teeth -4-4, hooked, without grinding surface. Translucent greenish
