 single flexible point. Lower jaw with a conical tubercle in front, 

 and with about nineteen stronger posterior teeth. The length of 

 the pectoral fin is about one-eleventh of the total, and more than

 posterior half of the pectorals. The first dorsal commences just 

 above the extremity of the pectoral, but behind the root of the
