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-

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 ! / 4 in 

 head, 2 ! / 4 2'/ 3 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 '/4 

 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,
