the barbel is shorter, the caudal region more slender, the rostral angles are 
much more prominent, and the rostrum hardly extends beyond the mouth.

The shape is somewhat like that of JZ. asper, but there is rather more 
distinction between body and tail. Body and head massive; head convex 
on all sides, bluntly pointed or rounded off in front with a low promi- 
nence and the common rosette of small spines, curvature slight from nape to 
end of snout, crown nearly flattened transversely. The ridge below the eye 
is a trifle swollen, but not angular. Depth of body nearly one sixth and 
length of head about one fifth of the total length. Snout short, blunt, 
rounded, three fourths as long as the eye, length from intermaxillary one 
half the orbital length, prenarial angles scarcely noticeable. Suborbital 
ridge low, rounded, marked by rough scales along its lower edge, vanishing 
before reaching a vertical from the hind border of the orbit. Interorbital 
space very little arched, width four fifths of the length of the eye. Eye 
large, two sevenths of the head, three fourths of the snout. Mouth large, 
length one and one fourth times that of the eye; maxillary extending below 
four fifths of the orbit. Teeth small, in villiform bands, outer series on the 
upper jaws larger. Barbel as long as the eye, slender. Preopercular ridge 
bent backward to form a rounded loop at the lower angle. Gill rakers 
short, rounded, rough with small spines, anterior series small, seven to eight 
on the first arch. Second dorsal spine above the opercular angle, including 
the filament three fifths as long as the head. First ray of dorsal above the 
base of the pectoral, second ray beset with sharp prickles on the forward 
edge; base less than the length of the eye, distant from the second dorsal 
less than twice this length. Rays of second dorsal short, feeble. Origin of 
anal below the third scale behind the base of the first dorsal. Ventrals 
small, first ray with a filament, length equal the distance from tip of snout 
to hind edge of orbit. Caudal small, slender. Vent distant from the anal
