pressed. Jaws covered by lips. Preorbital pentagonal or triangular, its apex directed upwards. Opening 
of mouth large : lower jaw with a knob at its extremity, received into an emargination in the end of the 
upper jaw. Cirri four ( Barilius , Ham. Buch.) on the snout; or two ( Bendilisis , Bleeker) on the maxillae, 
or none (Pachystomus, Heck el). Eyes with free lids. Pharyngeal teeth in three rows, pointed and 
curved. Dorsal fin without scales at its base, and placed above or behind the commencement of the ventral. 
Anal with more rays than the dorsal. Scales large or of medium size. Lateral line strongly concave. 
a. Without cirri (Pachystomus , Heckel).

Length of head \, of pectoral V of base of dorsal of base of anal ^, of caudal § of the 
total length. Height of head of body f, of dorsal , of anal of total length. 
Eyes—Diameter about ^ of length of head, 11 diameters apart, 1 diameter from end of snout. 
Profile more convex on the ventral than on the dorsal aspect. 
Gape of mouth large, directed forwards, and compressed from side to side. Lower jaw slightly 
the longest, terminating in a knob, which is received into the apex of a triangle formed by the 
meeting of the intermaxillaries. Lips not fleshy ; jaws entirely covered ; some pores exist along 
the margin of the lower lip, on the snout, and on the anterior margin of the preorbital. Sulcus 
single, not deep : snout rather enlarged at its extremity, and divided by a small fissure from the 
margin of the preorbital, which is pentagonal, its inferior border being the longest. Nostrils 
rather closer to the orbit than to the end of the snout, divided from one another by a membraneous 
valve, the posterior broad and open, the anterior with raised margins. Upper surface of head 
rather convex from side to side. 
Fins—Dorsal commences nearly midway between the snout and the base of the caudal, 
opposite the middle of the ventral, and extends backwards as far as opposite the fourth ray of 
the anal. Caudal deeply forked, the lower lobe the longest. Anterior margins of the dorsal and 
anal the highest, the former with a slightly convex, the latter with a concave margin. Base of 
dorsal scaleless, of anal scaled ; two long free scales at the base of the ventral; some scales at the 
base of caudal. 
Scales—Large and lineated. 
Lateral line—In single tubes on each scale. It descends nearly as low as the abdominal 
profile, and is continued nearly parallel with it. 
Teeth—Pharyngeal in three rows, curved, pointed, and slightly hooked at their extremities. 
They are arranged in the following order :—5,4,2 | 2,4,5. 
Colours—Back bluish grey, fading to white on the abdomen. Some metallic silvery blue 
spots along the sides. Dorsal, anal, and pectoral fins margined with white; their bases dark grey. 
Caudal grey in the centre and whitish externally.
