Form bearing some resemblance to F, cafenalus. Elongate, stout, com- 
pressed. Head about one fourth of the total length, crown flat. Snout 
broad, blunt, one and one half times the length of the orbit. Mouth of 
medium size; lower jaw longer, upper protractile. Teeth conical, in bands, 
outer series larger; pharyngeal with a shoulder, many of the median becom-

in advance of half way from snout to end of tail, about six rays forward of 
the origin of the anal; base extending several rays farther back than that 
of the latter; upper margin convex; hind angle acute. Anal elongate, 
lower angle acute, hind margin concave. Caudal broad, length slightly 
greater than that of the base of the dorsal, two thirds of the head, trun- 
cate. Ventrals small, not reaching the anal. Pectorals medium, reaching a

end of anal fin.
