52; of caudal vertebra 1 , 29: total, 81. The ribs and epiplcural spines arc 

 numerous, long and slender : the green colour of the osseous texture is a 

 peculiarity of this fish, which is still exhibited in the skeleton ; but it fades by 

 long exposure. Mta. South.

The bodies of the rertebne are elongated and excarated at their middle ; they
