FAMILY IX. TiENIDiE. 



Very similar to the Scombridse. They often have the elongated dorsal fin, 

 as well as the anal when it exists, united to the caudal. The articulated rays 

 are generally simple. The ventrals are frequently a single ray, or less than 

 five ; the position of these fins beneath the throat causes them to resemble the 

 Blennius. 



GENUS I. STYLEPHORUS, Shaw. 



Body very long, compressed. Snout lengthened, directed upwards, retrac- 

 tile towards the head by means of a membrane. Mouth without teeth. Eyes 

 pedunculated, standing on a short, thick cylinder. Branchia?, three pairs 

 beneath the throat. Pectorals small ; dorsal nearly as long as the back.
