12 + 6; L. lat. 94. 
Length of head 4.8, height of body 1.8, length of caudal 5.1; 
diameter of eye 7.6, length of snout 3.8 in the head. 
The rostral hook does not extend beyond the level of the 
lower eye, mouth small, lower lip with a fringe of ten rays on 
the coloured side only; lower eye half a diameter in advance of 
the upper one, interorbital space narrow, half the vertical 
diameter of the eye: gill membranes moderately united below, 
gill rakers very short, reduced to a mere fringe. 
Teeth. A narrow band of small teeth on the lower side of 
both jaws. 
Fins.—The dorsal rays commence at the tip of the snout, the 
first seven or eight being quite free, the rays on the head are 
elongate, those of the body are moderately uniform in length and 
short, the longest not exceeding a third of the head: the anal is 
quite similar and is coterminal with the dorsal, quite close to 
the base of the outer caudal rays; the right ventral corresponds 
to the anterior dorsal rays and the left, which lies opposite to 
the vent, has the rays similarly produced: the pectorals are very 
short, the right one being 1.8 and the left one 2.3 in the head; 
they are evenly rounded, the longest rays being in the middle: 
the caudal is short and boldly rounded. Owing to the juxta- 
position of the dorsal and anal rays there is no distinct peduncle, 
the depth at this point being 3.2 in the height of the body. 
ales.—Strongly etenoid on the right, smooth on the left side, 
entire head on both sides, including the interorbital space, scaly ; 
lateral line with a low arch over the pectoral, thence straight to 
the base of the caudal rays; the dorsal and anal fins are 
sheathed, the sheaths being more extensive on the right side, but 
there are no scales on the rays, the basal third of the caudal 
is wholly sealy, and scales are continued up the separate rays for 
another third. 
Colours.—General colour above brownish grey, each scale 
with a black mark on its outer edge; these form longitudinal lines
