This differs from both the preceding in having 

 the body nearly round, or at least iso obscurely 

 cornered as to appear round on a cursory view : it 

 is also entirely destitute of a tail-fin, the body 

 terminating in a naked point : it grows to the 

 length of two feet, and is chiefly found in the 

 Northern and Baltic seas. 



BIACULEATED PIPEFISH. 



Syngnathus Biaculeatus. S. ferrugineus, corpore tetragono, 



capite supra biaculeato. 

 Ferruginous Pipefish, with quadrangular body, and two spines 



above the head. 



Syngnathus biaculeatus. S. corpore quadrangulato, aculeis 

 duohus ad caput. Block, t. 121. 



Length six or eight inches : body somewhat 

 broader in proportion to its length than in the pre- 

 ceding kinds : dorsal fin placed low on the back : 

 tail hexagonal at its origin^ gradually becoming 

 tetragonal in its progress, and terminating in a 

 finless point or tip : colour of the whole animal 

 rufous brown. Native of the Indian seas, and also 

 said to be found in the Baltic.
