Pectorals narrow, inserted under the base of first dorsal. In tbo 

 smaller specimen they reach to the perpendicular from the niuth raj of 

 the second dorsal, in length equalling the greatest height of the body. 



Ventrais inserted at a distance from tip of snout equal to half the 

 length of anal base ; the second ray nearly twice as long as the first, and 

 in the smaller specimen, in which it is unmutilated, nearly as long as the 

 head. 



Radial formula :— D. 4, 53 ; A. 40 ; C. 5, 20 or 21, 5 ; P. 1, 19 ; V. C.
