i. tr. 5 + 18; Vert. 15 + 52 = 67. 
Length of head 4.4, height of body 6.4 in the length: diameter 
of eye 3.4, length of snout 2.7 and interorbital width 4.2 in the 
head. 
Snout long and very acute, whether viewed from above or in 
profile; longer than the eye; the latter is placed in the middle 
of the length of the head; the mouth lies below the space between 
the posterior nostril and (nearly) the hinder edge of the orbit, 
the gape is somewhat less than its length: the barbel is short, 
less than half the diameter of the eve: the nostrils lie near 
together close in front of the eye, the anterior one is an oval pore, 
the posterior one a long sub-vertical slit, rostro-infraorbital ridge 
nearly straight and strongly marked, the nasal ridge, which 
terminates between the eyes, is but slightly marked, the inter- . 
orbital ridges, at first parallel, diverge, and joining the origin 
of the lateral line distinctly mark off the head scales from those 
of the body; the supraorbital ridges are continued to the upper 
angle of the opercle and a temporal ridge arising above the 
posterior angle of the eye is continued to and in the same direc- 
tion with the lateral line. 
The body is compressed throughout its length and tapers 
evenly to the end of the tail. 
Fins —The dorsal commences at a point one and a half 
diameters behind the orbit, its first spine is minute, the second 
is slightly shorter than the succeeding and longest ray, and is 
not serrated; the space between the two fins is equal to the 
diameter of the eye and to the length of the base of the first 
fin; the rays of the second fin are short and le in a groove: 
the anal commences below the middle of the space between the 
two dorsals and is comparatively deep, its rays being equal to 
the eye; the pectoral extends to nearly below the origin of the 
second dorsal; the ventral arises beneath the hinder insertion 
of the pectoral and the outer lengthened ray reaches the base of 
the second anal ray.
