probably having a total length of not less than 0*45. Body slender 
and elongated ; head with opercular apparatus occupying about one-

first consisting of very stout rays and situated slightly in advance 
of the pelvic pair, the second consisting of more numerous slender 
rays ; principal caudal fin comprising 12-14 stout rays above and 
below. Jugular plates tapering in front, three to three and a half
