the front series in the upper jaw slightly directed anteriorly, 
the posterior rows slightly directed backward, give the im- 
pression of being recurved; on the palate a similar band of 
granular teeth. Some of the teeth are yellow or brown tipped. 
12 gillrakers on the lower branch of the first branchial arch, 
which has a rather high membrane at its innerside, decreasing 
anteriorly. Uniform brown. Head and anterior part of body 
darker. Length 120 mm. 
Habitat: British New Guinea (Inawi on the St. Joseph- 
or Paumomu-river !).

Height nearly equal to length of head, about 6. Profile from 
first dorsal sloping downwards in a straight line. Head nearly 
as high as broad. Skin of head finely granulated. Eye 5'/, in 
head, 2'/,—2'/, in convex interorbital space, about 2 in snout. 
Lips thick, irregularly papillated, the prominent upperlip partly 
laminated. Nasal barbels extend at least one eye diameter 
farther than the eye and may nearly reach to the hindborder 
of the operculum. Mandibular barbels reaching the middle of 
the base of the pectorals or a little farther. Mental barbels '/, 
shorter, maxillary barbels still shorter. Origin of first dorsal a 
little before origin of ventrals; its spine weakly serrated in 
front and behind, about as high as length of snout and eye, 
its soft rays as long as head without snout. Highest part of 
anal a little longer than snout; caudodorsal above the last 
third of the anal, represented by a low pad of fat from which 
the rays emerge and increase gradually in size. Ventrals 
rounded, extending to the anal, as long as postorbital part 
of the head. Pectorals as long as head without snout, nearly 
extending to the base of the ventrals, their spine shorter than 
that of the dorsal, weakly serrated along the hindborder. 
Maxillary teeth in a nearly continuous band of three rows; 
those of the mandibulary in two triangular patches of about 
5 rows, the vomerine ones in a semilunar patch of about 
5 rows. All teeth white. First branchial arch with a well 
developed membrane. 12 gillrakers on the horizontal branch 
of the first branchial arch, shorter than branchial filaments,
