extraordinary powers, I must recommend the de- 
scription by Dr, Garden in the Philosophical 
Transactions, and the highly accurate anatomical 
survey of the animal by the late Mr. John Hun- 
ter in the same work. 
After these examples of the first tribe or apo- 
dal fishes, I sliall proceed to those which Lin mens 
terms Jugular, as having the ventral or belly- 
fins placed before the pectoral or breast-fins. 
Of this division the genus called Trachimis, 
or Weever, may aftbrd an example. It is charac-
