»Length of head 3°/,,, of caudal fin 51/,, height of body 67/, 
in the total length. Diameter of eye 6'/, in the length of 
head, */, of that of snout, and ?/, of the interorbital space... 
The height of the head is °/, of its width, which is equal to 
its length behind the middle of the eye. Upper jaw so much 
the longer that the lower closes entirely inside the maxillary 
teeth; the width of the gape of the mouth is */, of the length 
of the head. Median longitudinal groove shallow and indistinct ; 
occipital process narrow, the width of its base being one half 
of its length, the sides are convergent behind to immediately 
in front of the basal bone of the dorsal fin round which they 
bend outwards; posterior part of the head granulated. The 
maxillary barbel reaches to the lower angle of the opercle, 
the external mandibular to the base of the pectoral. A broad 
band of obtusely conical villiform teeth on the jaws; the 
vomerine teeth form two small square patches, about their 
own length apart, and contiguous with the divergent palatine 
bands, which are thrice as long as broad. The dorsal fin is 
higher than the body, the spine as long as the head excluding 
the snout; it is roughened on its lower part anteriorly, weakly 
serrated on its upper half and posteriorly; the length of the 
base of the adipose dorsal is '/, more than that of the rayed 
fin; the pectoral spine is shorter than that of the dorsal, and 
is weakly serrated on both sides; the ventrals do not reach 
the anal fin. Caudal deeply forked. Colors, brown above, 
yellowish below; an oblong white spot on the middle of the 
occiput. Length of the specimen described 317 mm.” [After
