ZOOLOGY. 177 



AH the species are held iu high estimation as food ; they 

 Ihey are mostly marine, only resorting to fresh waters to 

 deposit their spawn; in search of situations proper for this 

 purpose, they ascend rivers, particularly such as abound with 

 rapids or falls, to overcome which, they throw themselves 

 out of the water to the height of many feet ; some of the 

 kinds are caught in nets, placed near the falls, and are 

 only accounted in season previous to their shooting (as it is 

 usually termed,) their spawn.

 spines on the back and abdomen. 



9. Teuthls. Head truncate ; gill membrane five rayed ; 



teeth equal, rigid, placed near together in a single row. 



10. Fislularia. Tobacco-Pipe Fish. Snout cylindrical; 

 jaws distant from the eyes ; gill membrane seven rayed ; 

 bodj/ round, gradually lessening from the head to the 

 tail. 



11. Essox. Pike. Upper jaw shorter than the ^otaer one ; 



teeth numerous, sharp, placed in the jaws, on the 

 tongue and palate ; dorsal and analfns, situated near 

 the tail, and mostly opposite to each other. 



A most voracious tribe, feeding on fish, often their own 

 species, are exceedingly destructive' to preserves of fish, the 

 great quantity they consume, being but ill repaid by their 

 increase in size, as the large fish are usually coarse, dry, and 

 insipid ; the marine kinds are generally cut to pieces, and 

 used as baits for other fish.
