COMMON SWORDFISH. 



lower : this part, which is commonly called the 

 sword, is flattish above and beneath, and sharp on 

 the sides : it is of a bony substance, covered by a 

 strong skin or epidermis : down the middle of the 

 upper part runs an impressed line or furrow, and 

 three similar ones on the lower surface : the tongue 

 is free or unconnected with the palate, and is of a 

 strong texture, and in the throat are certain rough 

 bones : the nostrils are double, and seated near the 

 eyes, which are moderately large, and protuberant : 

 the body is covered by a thin skin, having a thick 

 fatty membrane lying beneath : the lateral line is 

 placed near the back, and is formed of a series of 

 longish black specks : the dorsal fin is very high at 

 its commencement, and sinking suddenly, becomes 

 very shallow, and is continued to within a small di-

 process: the vent -fin is placed nearly opposite this 

 part beneath, and is moderately small, and much 

 wider at each extremity than at its middle: the 

 pectoral fins are rather small, and of a lanceolate 

 shape : the tail is large and crescent-shaped, and 

 on each side the body, immediately before the tail,
